Test/remove and install solenoid switch

~1min read

If the solenoid switch is defective, the pinion in the starter is not pulled into engagement with the flywheel ring gear.

As a result, the starter cannot crank the engine.

This fault occurs more often than the starter motor itself being defective.

Testing with the starter installed
  • Remove the gear, shift lever in neutral position.

  • Test requirement: battery fully charged.

  • Using a auxiliary cable, briefly bridge terminal 30 (= thick positive cable) and terminal 50 (thin cable, to the ignition switch) at the starter; the starter pinion must snap forward (click) and the starter must run. If not, unbolt the starter and test it removed.

Removal
  • Remove the starter and repeat the test with the starter removed using a car battery. A jump-start cable is suitable as the supply lead to terminal 50 of the starter.

    If the pinion snaps forward without the starter running, have the starter motor overhauled by a workshop.

Ausbau

  • If the pinion does not snap forward, unbolt the solenoid switch and replace it.

Installation
Einbau

  • Seal the joint - f - to the starter with a suitable sealant.

  • Hook the solenoid switch onto the fork lever in the starter, then bolt it on.

  • Bolt on the lead for the solenoid switch.

  • Test the starter again, as described above.

  • Install the starter.
