HOUR GAUGE CIRCUIT
The hour gauge circuit consists of the fuel/hour gauge, key switch, solenoid, and connecting wires (Figure
11-12, Page 11-13).
LIGHTING CIRCUIT
The headlights receive power through the fuse block when the light switch is pulled to the ON position (Fig-
ure 11-13, Page 11-13).
CIRCUIT TESTING
Read DANGER and WARNING on page 11-1.
Before testing the electrical circuits to determine the source of an electrical problem, test the vehicle battery
to determine whether or not it is the source of the problem. A hydrometer, multimeter, and 160 ampere load
tester will be required. See Test Procedure 1 – Battery on page 11-20.
