Starter Solenoid: Testing and Inspection

Magnetic Switch Pull-In Test

Magnetic Switch Pull-In Test:

1. Disconnect field coil wire from M-terminal of magnetic switch.
2. Connect a 12 V battery between S-terminal and M-terminal.

CAUTION: This test must be performed quickly (in less than 10 Seconds) to prevent coil from burning.

3. If pinion moves out, then pull-in coil is good. If it doesn't, replace magnetic switch.

Magnetic Switch Hold-in Test

Magnetic Switch Hold-In Test:

1. Disconnect field coil wire from M-terminal of magnetic switch.
2. Connect a 12 V battery between S-terminal and body.

CAUTION: This test must be performed quickly (in less than 10 Seconds) to prevent coil from burning.

3. If pinion remains out, everything is in order. If pinion moves in, hold-in circuit is open. Replace magnetic switch.

Magnetic Switch Return Test

Magnetic Switch Return Test:

1. Disconnect wire from M-terminal of magnetic switch.
2. Connect a 12 V battery between M-terminal and body.

CAUTION: This test must be performed quickly (in less than 10 Seconds) to prevent coil from burning.

3. Pull pinion out and release. If pinion quickly returns to its original position, everything is in order. If it doesn't, replace magnetic switch.
