4. A gap in a wire between the lock of ignition, a control bulb of a charging and the generator
5. A gap in a wire connected to weight, between the generator and the engine block
6. Graphite brushes were erased
7. The tension regulator is faulty
8. The generator is faulty
9. After too intensive washing of the engine the moisture which has got into it formed isolating film of greasing between
contact rings and graphite brushes


Start the engine an auxiliary wire or tow off the car
Check wires and accumulator plugs

Replace
Check conductivity a control bulb

Check a wire

Replace graphite brushes
Replace a regulator
Repair in a workshop the generator
If after a short trip there is no improvement, blow the generator the compressed air or wipe contact rings and graphite brushes

Century. The control bulb of a charging burns or decays at the working engine 1. The belt or defect in a tension roller is weakened poliklinovy
2. Insufficient contact in connecting knots of wires or wires are interrupted
3. See. And 6–8
Replace a belt or check the tension device
Check connection of wires and a wire
S.Poverkhnost of the accumulator the damp 1. The accumulator is overflowed
2. Accumulator jams got littered
3. See. And 7
Too large amount of the filled-in distilled water leaves with gases at the expense of a superfluous charging. Do not suck away acid
Clean ventilating openings
D. The accumulator strongly increases speed See. And 7
