Luggage Compartment Lamp Inoperative
CAUTION : Always make sure there is an electrical
load (lamp bulb, etc.) in any circuit between battery
terminals. Do not make a short circuit between bat-
tery terminals with a jumper wire. Hazardous spark-
ing will result.
Test Description
The number(s) below refer to step(s) on the diagnostic
table.
1. Bulb test. Clip one end of a jumper wire to the neg-
ative battery terminal. Clip the other end of the
jumper wire onto one end of the bulb. Take the free
end of the bulb (the end without the jumper at-
tached) and touch it to the positive battery terminal.
Step Action Value(s) Yes No
