Symptoms of malfunctions

1	The starter does not turn a bent shaft of the engine
2	The starter engine quickly rotates
3	The bent shaft of the engine rotates slowly
4	The control lamp of charging burns at the working engine
5	The discharged rechargeable battery
6	Admissions of ignition

The starter does not turn a bent shaft of the engine
STEP	CHECK		ELIMINATION METHOD
1	Check whether the bent shaft of the engine at completely charged rechargeable battery is turned	Yes	Check system of charging
		No	You watch the following step
2	Check whether tension on the plug B of the traction relay moves	Yes	You watch the following step
		No	Check a condition of wires
3	Check whether tension of the rechargeable battery to contact S traction relays moves at the pressed coupling pedal (on cars with the mechanical transmission) or at installation of the lever of the selector in a Park position (on cars with the automatic transmission) and turn of a key in the ignition lock in situation START	Yes	Replace a starter
		No	Check the switch of blocking of a starter of provision of a pedal of coupling (on cars with the mechanical transmission) Check the switch of range of transfers (on cars with the automatic transmission) Check the ignition lock Check a condition of wires

The starter engine quickly rotates
STEP	CHECK		ELIMINATION METHOD
1	Check whether the gear wheel of the obgonny coupling at inclusion of a starter will mix up	Yes	Remove a starter and check a condition of teeths on the obgonny coupling and a gear wreath of a flywheel
1		No	Replace a starter

The bent shaft of the engine rotates slowly
STEP	CHECK		ELIMINATION METHOD
1	Check the speed of rotation of a bent shaft at completely charged rechargeable battery	Yes	Believe system of charging
1		No	You watch the following step
2	Check reliability of fastening of wires of a starter and lack of corrosion for them	Yes	Repair or replace wires
2		No	Check lack of jamming of the engine of a starter. Repair or replace a starter

The control lamp of charging burns at the working engine
STEP	CHECK		ELIMINATION METHOD
1	Check tension of the rechargeable battery at an idling rotation frequency Voltage is 14,1 – 14,7 V	Yes	Check a condition of the wires connecting the rechargeable battery and contact of the L generator, the generator and a control lamp
1		No	Believe system of charging

The discharged rechargeable battery
STEP	CHECK		ELIMINATION METHOD
1	Believe system of charging	Yes	Include ignition and check current size, as shown in the drawing Current: less than 20 мА
1	Believe system of charging	No	If necessary, replace or repair details

Admissions of ignition
STEP	CHECK		ELIMINATION METHOD
1	In turn disconnect wires from each spark plug and check presence of a spark at an engine provorachivaniye a starter	Yes	Check spark plugs If spark plugs as it should be, a condition of electric system are normal If spark plugs not as it should be, clear or replace them
1		No	Check system of ignition

Diagnostics of malfunctions of system of charging and methods of their elimination

STEP

CHECK

ELIMINATION METHOD

Check the rechargeable battery

Tension: about 12,4 In

Yes

You watch the following step

Check the rechargeable battery

Launch the engine and check whether the control lamp of charging of the rechargeable battery burns

Yes

You watch a step 4

You watch the following step

Check, whether the correct tension on generator plugs

Specification

Contact	Ignition is included by ON, V	Tension, In
B	About 12	14,1 – 14,7
L	About 1	14,1 – 14,7
S	About 12	14,1 – 14,7

Yes

Check a condition of the wire connecting the rechargeable battery and contact In the generator

Check a condition of wires
Replace the generator

1. Turn on the ampermeter (with a limit of measurement at least 80 And) between the plug B and the plug In wires
2. Launch the engine
3. Switch off everything electric consumers and press a brake pedal
4. Check that the device shows current 65 A or more with ^{a frequency of rotation of 2500-3000 min.-1}

Prevention

Do not connect to "weight" contact In

Yes

You watch the following step

Make sure that a generator drive belt tension as it should be

Yes

Replace the generator

Adjust a generator drive belt tension
