ORGANIZATIONAL TROUBLESHOOTING - CONTINUED
MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
25. ALL TURN SIGNALS DO 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 turn signal switch (1) as follows: Disconnect batteries (page 2-424). Pull apart wire connectors (2
and 3). Push turn signal switch handle (4) to left turn position. Set multimeter to ohms scale and adjust to
0 ohms. Connect red test lead to wire terminal (5) and black test lead to wire terminal (6). Check for O
ohms on multimeter. Move black test lead to wire terminal (7). Check for O ohms on multimeter. Push
turn signal switch handle (4) to off position. Disconnect test leads.
a.
If multimeter reads no continuity on wire terminals (6 and 7), replace turn signal switch (1) (page 2-
744).
b.
If multimeter reads 0 ohms on wire terminals (6 and 7), go to step 9. Step 9. Push turn signal switch
handle (4) to right turn position. Connect red test lead to wire terminal (5) and black test lead to wire
terminal (8). Check for 0 ohms on multimeter. Move black test lead to wire terminal (9). Check for 0
ohms on multimeter. Push turn signal switch handle (4) to off position. Disconnect test leads.
Step 9.
Push turn signal switch handle (4) to right turn position. Connect red test lead to wire terminal (5) and black
test lead to wire terminal (8). Check for 0 ohms on multimeter. Move black test lead to wire terminal (9).
Check for 0 ohms on multimeter. Push turn signal switch handle (4) to off position. Disconnect test leads.
