CAUTION
This test must be performed quickly (in less than
10 seconds) to prevent the coil from burning.
3. Set the switch to "ON", and the pinion will move out.

1. Disconnect the field coil wire from the M-terminal
of the magnetic switch.
CAUTION
This test must be performed quickly (in less than

2. Connect a 12-volt battery between the S-terminal and M-terminal.
3. If the pinion moves out, the pull-in coil is good. If it doesn't, replace the magnetic switch.
