Clutch Switch: Testing and Inspection
Magnetic Switch Pull-In Test
1. Disconnect the field coil wire from the M-terminal of the magnetic switch.
2. Connect a 12 V battery between the S-terminal and the M-terminal.
CAUTION: This test must be performed quickly (in less than 10 seconds) to prevent the coil from burning.
3. If the pinion moves out, then the pull-in coil is good. If it doesn't move out, replace the magnetic switch.
Magnetic Switch Hold-In Test
1. Disconnect the field coil wire from the M-terminal of the magnetic switch.
2. Connect a 12 V battery between the S-terminal and the body.
CAUTION: This test must be performed quickly (in less than 10 seconds) to prevent the coil from burning.
3. If the pinion moves out, everything is in order. If the pinion moves back and forth repeatedly the hold-in circuit is open. Then replace the magnetic
switch.
Magnetic Switch Return Test
1. Disconnect field coil wire from the M-terminal of the magnetic switch.
2. Connect a 12 V battery between M-terminal and the body.
NOTE: This test must be performed quickly (in less than 10 seconds) to prevent the coil from burning.
3. Pull pinion out and release. If pinion returns quickly to its original position, everything is in order. If it doesn't, replace the magnetic switch.
