CORRECTIVE ACTION
35. ONE FRONT TURN SIGNAL DOES NOT WORK - CONTINUED.
WARNING
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
equipment.
NOTE
Scrape painted surfaces to bare metal before connecting test leads to ensure correct multimeter
readings.
Step 8.Test ground as follows: Using multimeter, set to ohms scale and adjust to 0
ohms. Connect red test lead to wire terminal (1) on wire connector (2) and black
test lead to ground on front turn signal assembly (3). Check for 0 ohms on
multimeter. Disconnect test leads.
a.
If multimeter reads no continuity, go to step 9.
b.
If multimeter reads 0 ohms, connect batteries (page 2-
779) and
go to step 12.
Step 9.Unscrew and take off two wing nuts (4) and junction box cover (5). Check two
11 wires (6 and 7) for loose, corroded, frayed, or broken condition.
a.
If two 11 wires (6 or 7) are loose, tighten nut (8) using
7/16-inch
open-end wrench.
b.
If two 11 wires (6 or 7) are corroded, using 7/16-inch
open-end
wrench, unscrew and take off nut (8) and two 11 wires (6
and 7).
Clean wire terminals (9 and 10) using wire brush. Place
wire ter-
