ORGANIZATIONAL TROUBLESHOOTING - CONTINUED
TEST OR INSPECTION
20. ALL LIGHTS DO NOT WORK - CONTINUED.
Although key switch must be on and negative battery cable connected to test electrical
circuit voltage, turn off key switch and disconnect negative battery cable before doing
resistance test or replacing parts. This will keep you from getting shocked and prevent
damage to parts and equipment.
Scrape painted surfaces to bare metal before connecting test leads to ensure correct
Test 8 wire (3) as follows: Disconnect batteries (page 2-424). Using 5/8-inch open-end wrench, unscrew
and take off nut (1), lockwasher (2), and 8 wire (3). Set multimter to ohms scale, and adjust to 0 ohms.
Connect red test lead to wire terminal (4) and black test lead to circuit breaker strip feed stud (5). Check
for 0 ohms on multimeter. Disconnect test leads.
If multimeter reads no continuity, 8 wire (3) must be replaced. Notify Direct Support
If multimeter reads 0 ohms, place wire terminal (4) and lockwasher (2) in position
and screw nut (1) onto terminal (6) of secondary magnetic switch (7) and tighten
using 5/8-inch open-end wrench. Connect batteries (page 2-424) and go to step 5.
Open left side hood panel (page 2-424). Set multimeter to 20 vdc scale. Connect red test lead to terminal
(8) on primary magnetic switch (9) and black test lead to ground. Check for 11 to 13 vdc on multimeter.
Disconnect test leads.
If multimeter does not read 11 to 13 vdc, install instrument panel pad (page 2-424)
and go to step 7.
If multimeter reads 11 to 13 vdc, go to step 6.
