(1) Combination Light Switch
Connector Voltage
1. Measure the voltage with a voltmeter across the connector B2
terminal and chassis when key switch is at "OFF" position.
2. Measure the voltage with a voltmeter across the connector B3
and chassis, B4 terminal and chassis when key switch is at
"ON" position.
3. If the voltage is different from battery voltage, battery, slow blow
fuse, fuse, key switch or wiring harness is damaged.

Checking Hazard Light Function
1. Measure the resistance with an ohmmeter across B2 terminal
and F terminal when hazard switch is at "OFF" position.
2. Measure the resistance with an ohmmeter across B2 terminal
and F terminal when hazard switch is in "ON" position.
