2. Remove instrument panel to access the back of the key switch but do not disconnect wires. See Instrument
Panel Removal on page 4-10.
3. With the key switch in the OFF position:
– The green wire should show battery voltage coming to the switch.
– The brown/white wire should show zero (0) volts. If it shows battery voltage, the switch has failed CLOSED
and must be replaced.
4. With the key switch in the ON position:
– The brown/white wire should show battery voltage passing through the key switch to sonic weld 3, the 5-amp
fuse, the solenoid, and the 4-pin connected car plug. If it does not show battery voltage, the switch has failed
OPEN and must be replaced.
TEST PROCEDURE 3 – Key Switch (START Position)

– The gray wire should show zero (0) volts. If it shows battery voltage, the switch has failed CLOSED and
must be replaced.
