Magnetic Switch Hold-In Test

Fig. 5 Magnetic Switch Inspection:

1. Disconnect field coil wire from "M" terminal of magnetic switch, Fig. 5.

Magnetic Switch Hold-In Test:

2. Connect a 12 volt battery between "S" terminal and body ground, Fig. 7. This test must be performed in less than ten seconds to prevent coil from burning out.
3. If pinion remains out, magnetic switch is operating correctly. If pinion moves in, hold-in circuit is open and the magnetic switch must be replaced.
