Fig. 4 Pinion Gap Adjustment (Part 1 Of 3):




1. Disconnect the field coil wire from the M-terminal of the solenoid.
2. Connect a 12 V battery between the S-terminal and the M-terminal.
3. The pinion will move out.

CAUTION: This test must be performed quickly (in less than 10 seconds) to prevent the coil from burning.
