Magnetic Switch Hold-In Test

WARNING: This page is about a different car, the 2017 Mitsubishi Mirage. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect the field coil wire from the M-terminal of the magnetic switch.
CAUTION: This test must be performed quickly (in less than 10 seconds) to prevent the coil from burning.
Connect a 12-volt battery between the S-terminal and body.
Manually pull out the pinion as far as the pinion stopper position.
If the pinion remains out, everything is in order. If the pinion moves in, the hold-in circuit is open. Replace the starter motor.
