2. Connect the black meter lead to the black wire (B);
then connect the red meter lead to the white/red wire
(A). then turn the key switch to the on position and
turn the light switch to the lights position. Then
repeat the test for low beam and high beam. Voltage
should be present.
NOTE: If no voltage is present on any setting (lights,

low beam, high beam) check the lights fuse, lights
switch, battery connections, battery, wiring harness,
lights relay. If no voltage is present on certain light
switch settings, check lights switch.
RESISTANCE (Headlight Switch)
1. Remove the plug from the center of the light switch;

VOLTAGE (Taillight)
NOTE: Perform this test at the socket end of the

taillight-brake light harness (pigtail). The ignition
switch must be in the ON position and either the
lights, high beam or low beam selected on the light
switch.
1. Set the meter selector to the DC Voltage position.
2. Connect the black tester lead to the black wire; then
connect the red tester lead to the white/red wire.
3. With the ignition key in the on position and the lights
on, the meter must show battery voltage.
 NOTE: If battery voltage is not shown and the head-
lights are illuminated, inspect the lights fuse. If bat-
tery voltage is shown on the meter, replace the bulb.
VOLTAGE (Brake Light)
NOTE: Perform this test at the socket end of the

taillight-brake light harness (pigtail). The ignition
switch must be in the ON position.
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the red/blue wire; then
connect the black tester lead to the black wire.
3.With the brake applied, the meter must show battery
voltage.
NOTE: If the meter shows no voltage, inspect the

10-amp lights fuse, brake light switch, wiring harness,
or connectors.
