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 the M-terminal.

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




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