Performance Test

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:
Connect the battery between terminals S and M on the solenoid. If the pinion protrudes, it is working properly.

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

Holding Coil Test:

Connect the battery between terminal S on the solenoid and the body. Manually pull out the pinion until it reaches the pinion stop. If the pinion does not snap back when it is released, the holding coil is working properly.

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

Retracting Test:

Connect the battery between terminal M on the solenoid and the body. Manually pull out the pinion until it reaches the pinion stop.
If the pinion retracts immediately when it is released, it is working properly.
NOTE: Do not leave the battery connected for more than 10 seconds.
