See Key Switch Removal, Section 12, Page 12-13.
3. Use a multimeter set on 20 volts DC, place alligator clips on the multimeter probes. Connect the black
(–) probe to the terminal block under the front body
(Figure 11-46, Page 11-43)
.

CAUTION
• Before connecting battery cables, make sure none of the electrical components touch the
front body trim or other parts of the vehicle frame. Place a dry towel between the body trim
and the center dash to prevent an electrical short.
4. Connect battery cables, positive (+) cable first, and tighten hardware to 12 ft-lb (16 N·m).
5. With the light switch in the OFF position, the reading should be zero volts. With the light in the ON posi-
tion, the reading should be between 11 and 12.5 volts. If there is no voltage reading, check continuity of
the 10-gauge red wire from the fuse block to the solenoid. Check continuity of the 14-gauge yellow wire
from the light switch to the fuse block. Check the fuse.
See Test Procedure 2 – Fuse on page 11-17.
If the wires and fuse show continuity and the readings are still incorrect, replace the switch.
