If the traction relay is damaged, the starter pinion does not engage the flywheel ring gear. As a result, the starter cannot start the engine. This malfunction is more common than a starter motor malfunction.

Check without removal



1. Set the gear shift lever to neutral position.

2. Test condition: The battery must be charged.

3. Short-circuit terminal 30 (thick positive cable) and 50 (thin cable to ignition switch) starter. The starter pinion should move forward (click) and the starter should start. If this does not happen, remove the starter and test it while it is removed.

Check with removal



1. Remove the starter.

2. Connect the battery with an auxiliary cable (starter) as follows to the starter and traction relay. Connect the negative pole of the battery to the starter housing. Briefly apply the cable from the positive terminal of the battery to terminal 50 of the relay. The starter gear should come forward.

Warning: The positive cable must be connected to terminal 50 for no more than 10 seconds, otherwise the relay coil will burn out.


3. If the pinion moves forward and the starter does not rotate, the starter motor must be repaired.

4. If the pinion does not move forward, replace the traction relay.

Removal



1. Remove the starter.

2. Unscrew the 2 bolts securing the traction relay.

3. Disconnect and remove the traction relay from the starter.

Installation
