Battery, alternator and starter - all together they are responsible for starting the engine
In order for each node to be able to perform its task, their consistency is needed
Without a battery, the starter will not move, without a starter, the engine will remain silent and the generator will not work.
And without a generator, the battery will not be able to replenish the spent energy.
Fault and its symptoms
- Probable cause
Remedy
Generator set:
- The voltmeter needle when the headlights are turned on at an average engine speed is located on the left in the extreme zone
a) alternator belt tension is loosened;
Adjust belt tension
b) contact rings are dirty;
Wipe the rings with a cloth soaked in gasoline
c) hanging brushes;
Remove voltage regulator, remove brushes, remove brush dust
d) short circuit in the stator winding of the generator;
Replace stator assembly or repair
e) malfunction of the voltage regulator;
Replace regulator
e) rectifier diode breakdown
Replace rectifier
- Noisy operation of the generator
а) wear or seizing of bearings
Replace bearings
b) rotor touching the stator poles
Replace bearings
Starter:
- When the starter is turned on, the traction relay is activated, but the starter does not turn the engine crankshaft or rotates it very slowly
- Wear of the contact surfaces of the switching parts of the relay
Replace the traction relay
- After starting the engine, the starter drive disengages, and the armature continues to rotate
- Welded traction relay contacts
Replace the traction relay
