TEST OR INSPECTION
23. BOTH HEADLIGHTS DO NOT WORK - CONTINUED.
Although KEY SWITCH must be on and battery ground cable connected to test electrical circuit
voltage, turn off KEY SWITCH and disconnect battery ground cable before doing resistance tests
or replacing parts. This will keep you from getting shocked and prevent damage to parts and
Scrape painted surfaces to bare metal before connecting test leads to ensure correct multimeter
Steps 24, 25, and 26 apply to malfunction of both hi beams.
To ensure correct multimeter reading, headlight beam selector switch (1) may have to be pressed to direct current to
terminal being tested.
Test headlight beam selector switch (1) as follows: Disconnect batteries (page 2-424). Remove center
instrument panel (page 2-424). Pull apart wire connectors (2 and 3). Set multimeter to ohms scale and
adjust to 0 ohms. Connect red test lead to wire terminal (4) and black test lead to wire terminal (5) on wire
connector (3). Check for 0 ohms on multimeter. Disconnect test leads.
a. If multimeter reads no continuity, replace headlight beam selector switch (1) (page 2-
b. If multimeter reads 0 ohms, go to step 25.
Unscrew and take off two wing screws (6) and junction box cover (7). Check two 52 wires (8 and 9) and
52A wire (10) for loose, corroded, frayed, or broken condition.
a. If two 52 wires (8 and 9) and 52A wire (10) are loose, tighten nut (11) using 3/8-inch
