Brake Release Switch Test

NOTE: The brake release switch is part of the stoplamp switch. The stoplamp circuit must be operating correctly before testing brake release switch.

Disconnect triple wire connector at regulator. Using a suitable test lamp, ground one test lamp lead and touch other to blue wire. Lamp should not light. If it does, wire is connected to wrong side of stoplamp switch. With brake pedal depressed 1/4", test lamp should light. If not, check fuse, stoplamp switch, wiring harness to regulator or power source connection.
