Starter Motor: Testing and Inspection

NOTE: Before starting the following checks, disconnect the wire from terminal M, and make a connection as described below using as heavy a wire as possible (preferably equivalent to the wire used for the car).

Pull-In Coil Test:

Pull-in Coil Test:
^ Connect the battery as shown. If the pinion protrudes, it is working properly.

NOTE: Do not leave the battery connected for more than 10 seconds.
