Starter Solenoid: Testing and Inspection

Pull-in Test of Magnetic Switch

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.

Hold-In Test of Magnetic Switch

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.

Return Test of Magnetic Switch

Fig. 9 Testing Magnetic Switch Return Function:

1. Disconnect field coil 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.
