Headlight Switch
This headlight switch allows the headlights to be turned
on and off and is located on the dash (Fig. 10)..
Testing
The headlight switch terminals are marked as shown in
Figure 11. The c ircuitry of the headlight switch is shown
in the chart below. With the use of a multimeter (ohms
setting), the switch functions may be tested to determine
whether continuity exists between the various terminals
for each switch position. Disconnect wire harness con-
nector from headlight switch and verify continuity be-
tween switch terminals for each switch position.

Brake Switch
The brake switch is a normally closed switch that is at-
tached to the frame under the dash (Fig. 12). When the
brakes are not applied, the brake pedal presses the
brake switch plunger to open the switch. When the
brakes are applied, the pedal moves away from the
brake switch plunger to allow the switch to be in the nor-
mally closed state and to allow a current path to illumi-
nate the stop lights.
Testing
1. Park vehicle on a level s urface, shut engine off, re-
move key from ignition switch and apply parking brake.
Locate the brake switch (Fig. 12).
2. Disconnect the wire harness connector from the
brake switch.
3. With the use of a multimeter (ohms setting), test for
continuity across the two (2) switch terminals. There
should be continuity (zero ohms) when the brake pedal
is depressed and there should not be continuity (infinite
ohms) when the brake pedal is released.
4. After switch testing is completed, connect the wire
harness connector to the brake switch.
