Electrical
Most electrical system problems show up as a burned out
light or fuse, or inoperative electrical component. Wiring,

symptom in this section that best identifies your electrical
problem. Check out each possible problem under that
symptom. If the problem cannot be located, see an
automotive electrical specialist. For maintenance
procedures, see
“Electrical System” on page 4-5.
