Magnetic Switch Pull-In Test

Fig. 5 Magnetic Switch Inspection:





1. Disconnect field coil wire from "M" terminal of magnetic switch, Fig. 5.
2. Connect a 12 volt battery between "S" and "M" terminals. This test must be performed in less than 10 seconds to prevent coil from burning out.
3. If pinion moves out, then pull-in coil is operating correctly. If pinion does not move out, replace magnetic switch.
