Installed check
Engage neutral gear at the checkpoint.
Using an auxiliary wire, bridge contacts 30 (for thick wire) and 50 (for thin wire from the ignition switch) - the starter gear should move forward (click), and the starter should work. If this does not happen, disconnect the starter and replace the traction relay.
Withdrawal
Remove the starter and repeat the test on the removed starter using the battery. An auxiliary wire to start the engine can be used as a wire to terminal 30. If the gear moves forward and the starter does not work, have the starter checked by a workshop.
If the gear does not move forward, remove the traction relay (F) and replace it.
Installation
Installation is carried out in the reverse order of removal.
