Reverse Switch Operation and Testing

Special Instructions

The reverse switch is a normally open ball switch. When the transmission is shifted into reverse, a ramp on the reverse shift yoke contacts and raises a pin. The pin depresses the ball on the switch, which closes the switch contact, allowing current to flow through the switch and light up the vehicle’s backup lights.

Special Tools

• Ohm Meter

Procedure -

1. Disconnect the wiring from the switch by lifting the connector locking tab and pulling the connector out of the switch.

2. Connect an ohm meter to test for continuity.

3. Place the transmission shift lever in any position except reverse. If the switch is working properly, the ohm meter should read open or infinity. If it is not, remove the switch and recheck it for continuity. Replace it as necessary.

4. Place the transmission shift lever in the reverse position. If the switch is working properly, the ohm meter should register continuity, or a small reading. If it does not, remove the switch and recheck it for continuity. Replace it as necessary.

Also, check for the presence of the reverse pin. Neutral Switch
