3. Check For Short To Ground
Turn ignition off. Remove 15 amp METER fuse. Disconnect kickdown switch harness connector. Check continuity between
Black/Yellow wire terminal of interior fuse holder and ground. If continuity exists, inspect and repair short circuit as needed. If
continuity does not exist, replace 15 amp fuse. Go to next step.
4. Check Power Supply To Kickdown Switch
Ensure ignition is off. Disconnect kickdown switch harness connector. Turn ignition on. Measure voltage between Black/Yellow wire
terminal of kickdown switch harness connector and ground. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less,
