Malfunction | Cause | Remedy |
The battery charging indicator lamp does not light when the ignition is on and the engine is stopped. | Control lamp burnt out | Disconnect wire "masses" from the battery, replace the lamp, connect the wire "masses" to the battery |
Broken circuit between generator (terminal D+) and control lamp (terminal 61) | Turn on the ignition, close the wire terminal 61 of the control lamp on "mass". If the lamp is on, repair open in the wire between the D+ terminal and the test lamp | |
Open circuit between alternator and control lamp | Disconnect blue wire (terminal D+) from the generator. Connect it to "mass". If the lamp is now on, replace the wire | |
Worn carbon brushes | Remove voltage regulator, replace carbon brushes | |
Break in the excitation winding or short circuit of the diodes | Replace rotor | |
Closed to "mass" wire between generator (terminal D+) and control lamp | Disconnect the blue wire from the alternator and turn on the ignition. If the lamp is on, replace the blue wire between the alternator and the 8-pin connector. If the lamp does not light, check the alternator and voltage regulator | |
Closed to "mass" wire between 8-pin connector and test lamp | Disconnect 8-pin connector (Tb) and turn on the ignition. If the lamp is on, replace the wire between the connector and the test lamp. If the lamp does not illuminate, replace the central wiring harness | |
Faulty voltage regulator | Have the regulator checked by a specialist workshop | |
Starter does not rotate when ignition is turned on | Low battery | Charge the battery |
The wire from terminal 50 of the starter to the ignition switch is broken, the starter switch is faulty | Connect terminals 30 and 50 of the starter: the starter should run. Find and fix the break, replace faulty parts | |
Broken wire or no contact with "weight" | Check the wires going to the battery and their connections | |
No voltage at the terminals of the excitation winding of the electromagnetic starter | Replace starter | |
Too little voltage at terminal 50 starter (less than 7 V) | Check the voltage at the ignition switch. If there is no voltage, replace the lock | |
There is no voltage at the terminals of the excitation winding of the electromagnetic relay | Replace relay | |
The starter turns too slowly and does not start the engine | Low battery | Charge the battery |
Wrong oil filled into the engine (summer winter) | Fill the engine with winter or all-weather oil | |
Poor current conduction due to poor terminal contact or oxidation | Clean battery leads and terminals, tighten connections | |
Clamped carbon brushes | Clean brushes and brush holder guides | |
Worn carbon brushes | Replace brushes | |
Collector dirty | Clear manifold | |
The collector has scratches and burn marks | Replace manifold | |
Armature or excitation winding defect | Repair starter | |
Starter works but engine does not start | Starter drive does not work or does not work properly | Replace drive. If necessary, repair the flywheel ring gear or replace the flywheel |
Starter motor not working | Drive thread dirty or damaged | Clean drive, replace if necessary |
Faulty magnetic starter | Replace starter |
