VOLTAGE (Wiring Harness Side)
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester to the orange wire; then
connect the black tester lead to the red/blue wire.
3. The meter must show battery voltage.
 NOTE: If the meter shows no battery voltage, trouble-
shoot the battery, fuse, switch, or the main wiring harness.
 NOTE: If the meter shows battery voltage, the main
wiring harness is good; proceed to test the
switch/component, the connector, and the switch wir-
ing harness for resistance.
RESISTANCE (Switch Connector)
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to one black wire; then
connect the black tester lead to the other black wire.
