On the latest models of motorcycles Planet 5-01, Planet 6, a 12-volt electrical system with a permanent magnet generator and an ignition system independent of the presence of a battery is used (Fig. 5.2). The new ignition system also provides automatic control of the engine ignition timing depending on the crankshaft speed.

Over the 50 years of IZH motorcycle production, the electrical system has fundamentally changed three times.

The 6 V electrical system with a 45 W DC generator was used on motorcycles from IZH350 to IZHPZ, IZHYUZ inclusive.

The increased intensity of the traffic flow and the emergence of special requirements for motorcycle lighting devices required a transition to a 12 V electrical system with an alternator with a power of 100-140 W. The disadvantage of this system in comparison with the previous one is a significant complication both in the number of devices and in switching. In addition, it requires a charged battery to start the engine, which is its disadvantage, both technical and economic for motorcycle consumers. Such a system is used on models IZHYu4, IZHP4, IZHYu5, IZHP5 (Fig. 5.1).

Note. On a motorcycle with a side trailer, the tail light of the side trailer is connected to the green and red wires that go to the tail light of the motorcycle (shown in dotted lines in the diagram). The wire from the turn signals of the side trailer is connected instead of the right rear turn signal of the motorcycle. The direction indicators on the right side of the motorcycle are moved to the side trailer. On motorcycles with joint lubrication pos. 4, 25 are not installed.

Depending on the functional relationships of individual devices and their intended purpose, the electrical equipment of motorcycles can be divided into the following main systems:

1. Power supply system (accumulator battery, generator, rectifier-regulator unit).

2. Ignition system (ignition coils, candles, candle tips, breakers).

3. Lighting system, light and sound signaling (headlight, side lights, brake lights, direction indicators, direction indicator interrupter, retroreflectors, sound signal).

4. Control and measuring devices (speedometer, light-optical signaling devices).

5. Switching and protective equipment (switches, circuit breakers, fuses).

6. Installation electrical products (tips, electrical wire connectors, electrical wires).

On motorcycles IZH-Planet, Izh-Jupiter, a single-wire electrical circuit is used, that is, the second wire connecting consumers to power sources is the mass of the motorcycle. The negative terminals of power sources and consumers are connected to the ground. The interconnection of all devices and assemblies of the electrical equipment of the motorcycle is carried out according to the wiring diagram (Fig. 5.1).

On motorcycles Planet 5, Jupiter 5, the ignition switch (lock) ensures that electrical equipment is turned on according to Table. 5.1.

Rice. 5.2. Electric circuit of the motorcycle IZH-Planet 5-01:

On a motorcycle with a side trailer, the rear side trailer light is connected to the connector of the green and red wires going to the rear light of the motorcycle (shown in dotted line in the diagram).

The operation and inclusion of all systems are controlled by the corresponding switches and switches. The supply voltage to all consumers is supplied through the ignition switch (lock).

Since 1995, on motorcycles IZH, instead of the switch 14.3704, the ignition switch 7.107-3704 has been used, which has 8 connection terminals. At the same time, on motorcycles Planet 5, Jupiter 5 (except Planet 5-01 and Planet 6), terminals 1 and 2 are not used, the wire from terminal 1 of switch 14.3704 (according to the wiring diagram) is connected to terminal 3 of switch 7.107-3704, from terminal 2- to terminal 5, from terminal 3 to terminal 6, from terminal 5 to terminal 7, from terminal 6 to terminal 8, respectively.

The battery and consumers of electricity on motorcycles IZHP5, IZHYU5 are connected in parallel to terminal X8 of the rectifier-regulator, that is, to the common point of the regulated voltage of the generator set. Such inclusion in separate circuits improves the conditions for charging the battery during motorcycle operation. The battery circuit is protected by a 10A maximum fuse. The fuse is located in the left tool box.

The ignition system of both models of motorcycles is battery, contact with mechanical interrupters.

The system is equipped with an engine kill switch located in the right combination switch.

The main difference in the electrical equipment of motorcycles is determined by the number of ignition coils, the design of the breakers and the circuit of the emergency engine switch.

On the Izh-Planet 5 motorcycle, equipped with a single-cylinder engine, one ignition coil and a G36M1 breaker are installed. Sat. 5 (Fig. 5.3, 5.12). The engine kill switch is connected to the negative terminal of the ignition coil and to the motorcycle ground. When the engine is stopped by the emergency switch, the low-voltage circuit of the ignition coil (primary winding) is connected to ground, sparking stops.

On Izh-Jupiter motorcycles equipped with a two-cylinder engine, two ignition coils and a G36M2 breaker are installed. Sat.Z with two pairs of contacts (Fig. 5.4, 5.13). The engine kill switch is connected to the negative terminals of the ignition coils. When the engine is stopped by an emergency switch, the ignition interrupters are electrically connected to each other, sparking stops. The emergency switch on the "Jupiter" functions normally with gaps between the contacts of the breakers within 0.4 ... 0.6 mm. With gaps of 0.7 mm or more, it is impossible to stop the engine with an emergency switch, since in this case the electrical connection between the breakers is not provided.

To connect electrical equipment components into a common circuit on motorcycles, flexible low-voltage wires of the PGVA type are used with a conductor cross section of 0.75, 1.0 and 2.5 mm in PVC insulation of the following 10 colors: blue, yellow, green, brown, red, orange, pink, grey, purple, black. The wires are connected to the electrical equipment units with automotive-type plug-in connectors, single plugs and lugs for screw terminals.

To connect the electrical equipment of the side trailers to the on-board network of motorcycles, single plug-in connections are provided, the connector of which includes the wires of the lights of the side trailer.

A feature of the wiring diagram of motorcycles Planet 5-01, Planet 6 with a permanent magnet generator is an ignition system that ensures engine operation regardless of the battery (Fig. 5.2). The ignition switch on motorcycles IZHP5-01, IZHP6 provides the inclusion of electrical equipment according to table. 5.2. A feature of the electrical circuit of the IZHP5-01 motorcycle is the presence of additional devices: a sensor and an ignition switch, as well as an extremely simplified scheme of the ignition system: a generator with a sensor - a switch - a coil - a spark plug. The ignition switch has 8 connection terminals (Fig. 5.14).

Possible malfunctions, ways to detect and eliminate them.

When the engine is not running and the ignition is on, the control lamp on the headlight burns with a weak glow. Check the degree of charge of the battery, connect to its terminals a brake light lamp from the rear light or a large headlight lamp. If the battery is in good condition, the lamp should glow normally. Check the reliability of the connection of the contacts of the electrical wires in the battery - central switch circuit.

The control lamp burns at all engine speeds with an even glow. First of all, check the operation of the generator, for which the “Sh” terminal of the generator is connected to “ground” and the lamp is connected to the “I” and “Sh” terminals. If, when the engine is running, the lamp does not light or burns with a weak glow, then the generator is faulty, and in this case it is necessary to check:

1. Ease of moving the brushes in the brush holder. In case of jamming, clean the brush holder.

2. The presence of contact between the brush and the current-carrying wire - external examination. Replace brush if necessary.

3. The presence of contact between the brushes and the commutator, the absence of the brush hanging in the brush holder on the wire - external inspection, if there is no contact due to heavy wear, replace the brush.

4. The condition of the collector surface - external inspection, in case of contamination or oiling of the surface of the lamellae, rinse the collector with gasoline or clean it with glass sandpaper.

5. Check the serviceability of the excitation coils of the generator stator. Disconnect the wires coming from the bundle from the terminals "M", "I", "Sh" of the generator without removing the output wires of the excitation coils from the terminals "I" and "Sh". Disconnect the output wire of the excitation coils (additional resistance) from the ground. Then connect one terminal of the battery to the terminal of the generator "I" or "Sh". Connect any motorcycle lamp in series to the second terminal of the battery, and the second contact of the lamp to the free terminal "I" or "W".

If the lamp does not light up, then there is an open in the excitation coils (usually due to the lack of contacts at the junctions of the excitation coils). It is necessary to check the joints of the coils, and if necessary - solder.

If there is no open circuit in the excitation windings, i.e., the lamp is on, then it is necessary to additionally check that the excitation windings are not shorted to ground. To do this, connect one terminal of the battery to the "mass" of the generator, and the second - through the lamp to the terminal "I" or "Sh". If the lamp does not light, then there are no short circuits and the generator stator is working. If the lamp is on, then you should find the place of the circuit. To do this, remove the stator from the engine and re-check the absence of a short to ground in the stator coils as indicated above. If the short circuit is eliminated after removing the stator, then it was caused by the contact of the screws securing the generator to the excitation coil due to insulation failure or by the contact of the screws with the wires of the excitation coils at the joints. Troubleshoot. If the lamp is on when the stator is removed, then the excitation coil is closed by contact with the pole. To determine the location of damage, alternately disconnecting the excitation coils from each other, check each for the absence of a short circuit with the "ground" in the above way. Put the damaged coil back to rest by unscrewing the screws securing the pole, and put insulation on the damage site, securely fasten the coil with the pole to the stator.

It should be borne in mind that if the screws for fastening the pole are not tightened enough, it may touch the anchor. If the stator is good, but the generator is not working, then the armature is faulty. The anchor needs to be replaced.

The generator is working, but the control lamp burns with an even glow at all engine speeds. Check the operation of the relay-regulator. First, with the engine running, check whether the contacts of the reverse current relay are closing. If there is a contact closure, i.e., the armature is pulled up, then it is necessary to turn off the engine, turn off the ignition and, with the battery disconnected, clean the contacts of the reverse current relay with a safety razor blade. It is unacceptable to clean the silver contacts of the relay with emery or glass sandpaper, since in this case the abrasive cuts into the metal and breaks the electrical contact.

If the relay contacts do not close, and the armature is attracted , then you should check the adjustment of the gaps and the moment of operation (section "Relay-regulator"). In the event that the armature is not pulled up and the contacts do not close, check the adjustment of the regulator, since the reverse current relay may not work at low voltage.

The control lamp goes out only at high engine speeds. The reason is the low voltage maintained by the relay-regulator. Check and adjust voltage regulator.

When the engine speed increases and the light is on, the lamps burn with overheating or burn out - due to the high voltage maintained by the relay-regulator. Check and adjust voltage regulator.

The control lamp at increase in turns of the engine burns with overheating . The battery is connected incorrectly (reverse polarity of the battery terminals) or the alternator is reversed.

Check and, if necessary, correctly connect the battery to the electrical circuit. If the battery is connected to the electrical circuit correctly, then the generator is reversed. To reverse the polarity of the generator, it is necessary to open the relay-regulator and, with the ignition on, but the engine not running, briefly close the contact of the reverse current relay.

When the ignition is turned on without pressing the button, a signal sounds. The signal wire is shorted to ground. Remove the light switch from the steering wheel and, if the signal continues to sound, find the short circuit of the signal wire. If the sound of the signal stops when the light switch is removed from the steering wheel, then a short to ground occurs in the switch.

When you press the foot brake pedal, the rear brake light does not come on. Check lamp. If it is working, check the correct installation or adjustment of the brake light switch.

At one of the positions of the central switch and the light switch, the lamp corresponding to this position does not light.The reason is a lamp burnout or a broken contact at the junction of the wires. Check the lamp with the battery, replace if necessary. If the lamp is in good condition, using the electrical circuits, check the presence of contacts in the lamp sockets and the reliability of the wires at the junctions.

Reverse current relay. In the electrical system of a motorcycle, the battery and alternator are connected in parallel. With an increase in the number of revolutions of the crankshaft of the engine, the number of revolutions of the generator armature increases, and hence its voltage. Therefore, if there is no regulating device in the generator-battery circuit, then the battery will be systematically recharged when the generator voltage increases, which will lead to its failure. If the generator voltage is lower than the battery voltage, then the latter will be discharged through the generator, which may also become unusable.

The functions of such a control device are performed by a reverse current relay (ROT). To ensure the normal operation of consumers installed on the motorcycle, as well as a rational mode of charging the battery within the specified limits, a special voltage regulator (PH) device is included in one unit with a reverse current relay.

The reverse current relay consists of an electromagnet core 4, an armature 3 with a spring 12, two contacts 1, 2 and a yoke 13. Two windings are wound on the core: a thin shunt (SHO) and a thick serial (CO). In the free state and at idle (low) engine speed, the contacts are in the open state and all consumers are powered by batteries. With an increase in the number of revolutions of the generator armature, the voltage in the network increases. Accordingly, the current passing through the thin winding (SW) increases, the core attraction force overcomes the spring force, the armature is attracted to the core, the contacts close, and the electric current from the generator goes to charge the battery and to other consumers. As soon as the generator voltage drops below the battery voltage, the relay contacts will open under the action of the spring.

Voltage regulator consists of an electromagnet core 7, an armature 6, fixed and moving contacts 5, a return spring 8 and resistances 9, 10. Three windings are wound on the core of the voltage regulator: shunt - SHO, compensation - KO and serial - CO. When the generator armature does not rotate or rotates at a low number of revolutions, the two-way movable contact of the voltage regulator is pressed against the upper fixed contact connected to ground by the force of the armature spring. In this case, the excitation winding 11 of the generator is connected to ground through the compensation winding KO and contacts 5 of the regulator.

With an increase in the number of revolutions of the generator armature, the electric current passing through the serial winding magnetizes the core of the electromagnet and attracts the armature 6 of the regulator and its two-sided contact 5 moves to the middle position, that is, it opens. In this case, resistances 10 and 9 connected in series at 4.4 and 1.2 ohms are included in the circuit of the excitation winding of the generator and the compensation winding. With a further increase in the number of revolutions of the armature, the additional resistance is not enough to prevent an increase in the generator voltage in excess of the specified limit. Armature 6 is strongly attracted to the electromagnet and double-sided contact 5 is pressed against the lower fixed contact, short-circuiting the excitation winding of the generator. The generator voltage decreases, the voltage regulator armature returns to the middle position or closes with the upper fixed contact. Vibrating, armature 6 with double-sided contact maintains the generator voltage in the range of 6.5-7 V.

When the generator is overloaded, the serial winding of the regulator, additionally magnetizing the electromagnet, limits the maximum generator current.

Possible malfunctions of the voltage regulator and care for it. The voltage regulator is adjusted at the factory and this setting should not be violated unnecessarily. Care comes down to monitoring the condition of the wires attached to the relay terminals and keeping it clean.

A malfunction of the voltage regulator disrupts the operation of the entire electrical system. The main signs of a malfunction are: bright burning of lamps or their burnout. The electrolyte boils away and the battery drains quickly, especially when the motorcycle is used at night. During operation of the motorcycle, control over the operation of the regulator is carried out by the red control lamp located in the headlight.

Turning on the control lamp at speed (1100 - 1200 rpm) indicates a malfunction of the regulator or generator.

Operating the motorcycle with the warning light on will drain the battery. The relay-regulator is a very sensitive device and you can entrust its adjustment to a highly qualified specialist.

Checking and adjusting the voltage regulator is carried out at idle speed of the generator, that is, without any loads. Therefore, between contacts 1 and 2 of the reverse current relay, it is necessary to lay an insulating gasket made of paper. In this case, the ignition coil will be powered by the battery. Connect a voltmeter to terminals "I" and "M". Start the engine. At medium engine speeds, the voltage should be in the range of 7.3-7.8 V. If the voltage goes beyond these limits, then first you should clean the contacts 5 with a steel plate (razor blade), 0.05-0.1 mm thick, but in no case with an emery cloth. Cleaning should only be done with the engine off. If the stripping did not give positive results, you should check the gap between the armature and the core of the electromagnet 7 (0.9-1.1 mm), as well as between contacts 5.

The gap between the contacts 5 is checked as follows: between the armature 6 and the core of the electromagnet 7, insert a probe 1 mm thick and press the armature to the core. At this moment, the gap between contacts 5 should be 0.25-0.30 mm (checked with a second probe). If the gap is not maintained, it is necessary to bend the holder of the upper contact. Check clearances and tension again. If necessary, the voltage can be adjusted by changing the tension of the armature spring 8 by bending the lower spring holder. With increasing spring tension, the voltage in the circuit will increase, with weakening, it will decrease. It is necessary to bend the spring holder when the engine is not running, and when checking the voltage with a voltmeter, the engine must run at high speeds.

After completing the adjustment of the voltage regulator, remove the insulating gasket from the gap between the contacts of the reverse current relay.

Checking and adjusting the reverse current relay. To check and adjust the reverse current relay (ROT), you need an ammeter with the zero position of the arrow in the middle of the scale (scale 5-0-5A). The voltmeter is connected in the same way as when adjusting the voltage regulator, and the ammeter is connected in series to the battery.

Before proceeding with the adjustment, it is necessary to check the compliance of the gaps, the value of which should be: between contacts 1 and 2-0.25-0.35 mm and between armature 3 and the core of the electromagnet - 0.6-0.8 mm. If it is necessary to adjust the gap between the armature and the core, the contact holder must be moved with the screws loosened.

The gap between the relay contacts is adjusted by bending the contact post. To check the voltage, you need to start the engine and, gradually, adding speed, notice the voltage at which contacts 1 and 2 close. At the moment of closing the contacts, the needle of the voltmeter shudders slightly. The contacts should close at a voltage of 6.0-6.4 V. The reverse switching current of the relay with correctly set gaps and switching voltage should be within 0.5-4 A. If the contacts close at a higher voltage, then the lower spring holder 12 must be bent upwards, weakening the spring force. If it is less, then bend the spring holder down. Adjustment is made at low speeds.

The main visual difference between the two motorcycles of the IZH family is the number of engine cylinders. The Jupiter 5 model has two of them, while the Planet 5 has only one.

In all other respects, the models are maximally unified with each other, with the exception of electrical components.

For reference: another design feature of the IZH Jupiter of the last 5 years of production is the use of water cooling.
And Planet 5 has all air-cooled engines.

Despite the unification of parts with other models, the IZH Yu5 wiring diagram was selected for battery use..

We are talking about a contact ignition system, which, with a “dead” battery, immediately creates problems for the owner:

1. Starting the engine is difficult;
2. The engine runs intermittently;
3. Driving at low speeds further drains the battery.

For reference: unlike the Jupiter model, a new wiring and an electronic ignition system were installed on the modified IZH Planet 5.
The methods proposed below are just designed for simplified work - not requiring a major replacement of components.

Transition to contactless ignition system

But there is a more advanced way, in which:

1. The generator and wiring on IZH Jupiter 5 remain;
2. Minor alterations are made to the electrical circuit;
3. The battery is left to service auxiliary systems.

We are talking about the modernization of the ignition system with the combined use of elements from the VAZ-2108 car and the Planet 5 motorcycle.

At the same time, the wiring diagram for IZH Jupiter 5 is preserved:

1. Two Hall sensors are installed;
2. Two electronic switches are connected to them (points 1 and 2 - with VAZ). Each pair of sensor-commutator services 1 cylinder;
3. Two ignition coils from a motorcycle of the IZH family.

In the diagram above, the numbers indicate:

1. Spark plug;
2. Coils Planet 5;
3. Switches from the "eight";
4. Hall sensors from the "eight";
5. Egnition lock;
6. Accumulator battery.

Refinement of the generator

This technology for switching to a contactless ignition system is interesting in that the motorcycle owner does not need to buy a new generator designed to work in an electronic ignition system. Accordingly, the cost of alteration will be minimal.

Enough:

1. Make a modulator that will interrupt the circuit;
2. And install it on the generator (on the rotor shaft).

A metal plate with a hole drilled in it for a mounting bolt can serve as such a modulator-interrupter.

The order of installation of the modulator is as follows:

1. The modulator plate (in the diagram below under No. 2) is installed under the mounting bolt;
2. Slightly attracted to him;
3. By rotating the crankshaft, set the piston to TDC;
4. We set the ignition timing;
5. Tighten the plate with the fixing bolt.

For reference: in addition to the modulator, it is installed under the engine cover and two Hall sensors (in diagram No. 1). There are places to mount them.

Improvement of the regular system

For those owners who do not want to switch to a contactless ignition system, there are other ways to improve sparking.

At the same time, the wiring of the IZH Jupiter 5 motorcycle is analyzed for problem areas, and most often:

1. The primary circuit from the battery to the coil is diagnosed;
2. Places of voltage drop caused by operating conditions are identified.

A simple inspection of the primary circuit will demonstrate several problem areas at once:

1. four plug connectors;
2. emergency ignition switch;
3. contacts of the central switch;
4. interrupter contacts.

Under ideal operating conditions, such a complex section of the chain will work flawlessly.

But in practice, it is exposed to dirt dust flying from under the wheels, therefore, in the circuit due to an increase in resistance at the points of contact:

1. the voltage decreases from 12 V to 7-8 V;
2. this is not enough to excite a powerful discharge of the secondary winding of the coil;
3. as a result - a low discharge on the candle, making it difficult to ignite the combustible mixture in the cylinders.

And if we add to this a “dead” battery and oily candles with burnt contacts, then the process of sparking becomes completely problematic.

Motorcyclists solve such defects as follows:

1. traditional soldering. The wiring on IZH Yu5 gets rid of plug connections and each wiring is tritely soldered by hand, followed by insulation;
2. installation of an additional toggle switch (in diagram No. 1), which turns off all consumers at the time of starting the engine. This allows you to apply the maximum voltage from the battery to the coil;
3. alteration of the ignition lock. A wire is soldered to the free connector of lock 4 (in diagram No. 2), the second end of which is fed to the positive terminal of the coil.
   The standard ignition wire from terminal 5 is transferred to terminal 6, and when this key position is activated, a simplified scheme for supplying power from the battery to the primary circuit of the coil is activated.

Conclusions: you can learn from this article not only proven ways to improve the electrical part of a motorcycle (as in the article about), but also watch video materials that clearly demonstrate the modernization work algorithm.

"Planet-sport" is the first Izhevsk motorcycle with 12-volt electrical equipment that meets all modern (as of 1982) requirements for this system.

The optical element of the Hella company in the headlight was replaced by the Soviet FG 137, and the IZH UP1 lamps of the direction indicators were replaced by unified lamps 16.3726. There are other innovations as well.

Jupiter-4 is now also equipped with 12-volt equipment. The plant is also preparing for production a new Planet-sport model, the electrical equipment of which is unified with Jupiter-4.

However, already now the owners of Planet-Sport can use a number of IZH Yu-4 electrical appliances without significant alterations. These include generator 28.3701 (if it is sold without a breaker and a capacitor, they can be taken from the old IL GP1); direction indicator lights 16.3726; optical element of headlight FG 137; rear lamp FP146; speedometer SP102; rechargeable battery 6MTS-9.

To install the turn signal interrupter IZH RP2SM-10 into the headlight housing, it is necessary to make an additional bracket from a steel strip 1-1.5 mm thick and replace the plug-in tips with round ones. After the same alteration of the tips, the combined switches IZH P101-20 and IZH P102-20 from the IZH Yu-4 motorcycle can also be used on Planet-Sport. To do this, pressing the fixing antennae with an awl or a knitting needle, remove the plug tips. They are cut off and round tips are crimped and soldered on the stripped ends of the wires. At the IZH P101-20 switch, a blue outlet wire 130-150 mm long with a plug tip is also soldered to the black wire.

The improvement of the electrical equipment of motorcycles and the use of new devices have naturally led to some complication of the electrical circuit. Let's get acquainted with its main elements using the example of the electrical equipment of the Planet-Sport scheme, which is in many ways similar to the schemes of other Izhevsk motorcycles.

Ignition system. This is perhaps the main system, because without it the motor cannot work. Let's trace and remember its electrical circuit. From the battery 24, through the fuse 25 and the rectifier 26, power is supplied to the terminal (2) of the connecting panel in the headlight housing and then to the terminal (3) of the ignition switch 9. When the key is turned to position I, the terminals (3-2 - 1 and 5 -6). Now, from the terminal (1) of the lock, the current goes to the terminal (5) of the connecting panel, from it to the emergency ignition switch 11, and through its closed contacts to the terminal (1) of the connecting panel and then to the primary winding of the ignition coil 21 (the second end of the primary winding - the "-" terminal is connected to the breaker). Thus, the circuit of the motorcycle ignition system is turned on.

If the engine does not run due to the absence of a spark at the plug, check if high voltage is being supplied to it. To do this, remove the wire from the cap and bring it to the edge of the cylinder with a gap of 2-3 mm. If no spark appears between the wire and the cylinder when the crankshaft is rotated by the kick starter, there is no high voltage. The reason for this is found as follows. When the ignition is turned on, a 12-volt test light is used to check whether power is supplied to the “+” terminal of the ignition coil. If not, then check the entire circuit, starting from the battery. A common cause of no voltage is loose or oxidized terminals, or a faulty fuse.

Having achieved that a normal voltage appears on the “+” terminal of the ignition coil, carefully clean the breaker contacts, check and set a gap of 0.4-0.6 mm between them and adjust the initial ignition timing.

If the engine gives only separate flashes at start-up, and a white coating appears on the breaker contacts, it means that the capacitor has failed (rarely, but this happens).

With the correct gap, clean breaker contacts and a working capacitor, the reason for the absence of a spark on the candle may be a malfunction of its plastic cap (breakdown to ground) or the ignition coil (it is non-separable, so it is replaced). A bad spark plug can cause the engine to misfire or make it difficult to start. Alarm and lighting system

direction indicator. When the ignition is turned on (the key is in position I), electricity from the battery 24 (or rectifier 26 when the engine is running) is supplied through the terminals (3 and 1) of the ignition switch 9 to the terminal (5) of the connecting panel. The power wire of the relay 6 of the direction indicators, the sound signal 18 and the "positive" wire of the light switch 11 located on the steering wheel are connected to it. From relay 6, power is supplied to the lights through the terminal (9) of the connecting panel and then to the switch 19 of the direction indicators. From it, through the terminals (6 and 7) of the connecting panel, it goes to the lights 10 and 28 of the direction indicators. The control lamp 16 of the direction indicators is also connected to the terminals (6 and 7) of the connecting panel through the block of diodes 7.

The reason for the failure of the direction indicators most often is the lack of "mass" in the lamps when their fastening to the frame is loosened, oxidation or loosening of the connections of the tips with wires, contacts in the lamp sockets.

To speed up troubleshooting, the circuit is checked from the idle consumer to the power source. To determine the operability of the relay 6 of the direction indicators without dismantling it, you must first make sure that the terminal (5) of the connecting panel is energized, and the brown wire of the relay is securely connected to ground. Then check the continuity of the circuits going to the direction indicator lamps by connecting terminal (5) with terminals (6 and 7) of the connecting panel with a separate wire. The lights of the right (terminal 6) or port side (terminal 7) and the control lamp 16, if the circuits are in good condition, should burn without blinking. Then disconnect the pink relay wire from terminal (9) and connect it to terminals (6 and 7) of the connection board. With a working relay, the lights of the starboard or port side should flash at a frequency of 60 to 120 per minute.

The relay removed from the motorcycle is checked using two A12-21-3 control lamps (power of each 25 W) connected in parallel. Connect the “plus” of a constant voltage of 12 volts to the red wire, “minus” to the brown one, and control lamps to the pink one. With a working device, the lamps should flash at a frequency of 90 ± 30 per minute.

Farah. It contains the main part of the wiring diagram, the turn signal relay, the neutral 3 and oil pressure warning lamps 5, the lamp 8 illuminating the speedometer scale, the parking light lamp 1, the head light lamp 2, the ignition switch 9 and the speedometer.

On the latest models of motorcycles, the turn signal breaker is mounted on the frame under the gas tank.

Consider the electrical circuit of the head, parking and clearance light. With the ignition on (key in position I), power is supplied to the terminal (4) of the connecting panel, then through the contacts of the light switch 11 to the central contact of the high-dipped beam switch 19. Then through the terminals (11 and 12) of the connecting panel - to the thread of the high or low beam of lamp 2.

The position light in the headlight (bulb 1) and in the rear lamp 29 lights up when the switch 11 is activated and current flows through the contacts (5 and 6) of the ignition lock 9.

If the ignition key is turned to position II (parking), then these lamps are powered through its contacts (3 and 5) regardless of the position of the switches on the steering wheel.

Lamps that dimly glow when the engine is not running indicate that the battery is not fully charged. If this is observed in all engine operating modes, it means that the voltage in the lamp supply circuit drops sharply. In this case, check the electrical connections of the power and ground wires, clean and tighten the screw and plug connectors, the contacts in the lamp sockets of the headlights and lanterns. Check the serviceability and reliability of the contacts in the switches and fuse.

Since the motorcycle is constantly being improved during the production process and its electrical circuit changes, it is advisable to mark the differences of your motorcycle in the circuit printed here so that, using it, you can always easily and quickly find the right circuit and determine the malfunction.
