40. ONE FRONT EMERGENCY FLASHER 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. Check for 0 ohms on multimeter. Disconnect test leads.
a. If multimeter reads no continuity, go to step 9.
b. If multimeter reads O ohms, put wire connector (2) into front turn
signal assembly (3).
Step 9. Unscrew and take off two wing screws (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 7/16inch
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 terminals
(9 and 10) in position and screw nut (8) onto terminal stud (11)
