List of starter faults and their elimination (Opel Omega B2)

The main conditions for testing the starter are reliable electrical contacts without oxidation.

The starter does not rotate when the key in the ignition switch is turned to the appropriate position

The battery is discharged

• Charge the battery

Short-circuit starter terminals 30 and 50. If the starter starts, then the wire of terminal 50 leading to the ignition switch is broken or the starter switch is faulty

• Fix the break. Replace the faulty parts

Break or poor connection of the ground (-) wire. Battery is discharged

• Check the wiring and contacts. Measure the battery voltage. Charge it if necessary

Insufficient current conductivity due to weak or oxidized contacts

• Clean the battery terminals and poles. Restore the reliability of the connections between the battery, starter and "ground" (-)

No voltage at terminal 50 (traction relay)

• Wire break. Ignition and starter switch malfunction

The starter turns too slowly and does not turn the engine over

The battery is discharged

• Charge the battery

Insufficient current conductivity due to weak or oxidized contacts

• Clean the battery terminals and posts, as well as the starter wire ends. Tighten the starter wire nuts

Carbon brushes do not fit the commutator, are stuck in the guides, are worn out, broken, oily or dirty

• Check the carbon brushes and terminals, clean them or replace them. Check the carbon brush guides

Insufficient distance between carbon brushes and commutator

• Replace the carbon brushes and clean the carbon brush guides

The collector is worn out, burnt or dirty

• Turn the collector or replace the anchor

No voltage at terminal 50 (less than 10 V)

• Check the ignition switch or traction relay

The traction relay is faulty

• Replace the traction relay

The starter engages and spins, but the engine does not turn over or turns over jerkily

The gear transmission is faulty

• Replace the gear

The starter gear is dirty

• Clean the gear

The flywheel ring gear is damaged

• Straighten the ring gear and replace the flywheel if necessary

The gear transmission does not disengage

The gear or helical splines are dirty or damaged

• Clean the gear and replace it if necessary

The traction relay is faulty

• Replace the traction relay

The return spring is weak or broken

• Replace the return spring

The starter continues to rotate even after the ignition key is released

The traction relay is stuck and won't turn off

• Turn off ignition immediately. Replace traction relay

The ignition switch does not turn off

• Disconnect the battery immediately. Replace the ignition switch
