Magnetic Switch Pull-In Test

Magnetic Switch Pull-In Test:

1. Disconnect the field coil wire from the M-terminal of the magnetic switch.
2. Connect a 12 V battery between the S-terminal and M-terminal.
3. Manually pull out the pinion as far as the pinion stopper position.


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


4. If the pinion moves out, the pull-in coil is good. If it doesn't replace magnetic switch.
