Magnetic Switch Pull-In Test
- Disconnect the field coil wire from the M-terminal of the magnetic switch.
- Connect a 12V battery between the S-terminal and the body.
- Connect the field coil wire to the M-terminal, and then disconnect it.CAUTION: This test must be performed quickly (in less than 10 seconds) to prevent the coil from burning.
- If the pinion moves out, then the pull-in coil is good. If it doesn't move out, replace the magnetic switch.
