Organizational Troubleshooting (continued)
MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
1.
(continued)
a. If no voltage, do step 4.
If voltage is good (22 to 26 vdc), disconnect battery,
b.
replace BATTERY VOLTAGE meter 1M4 (paragraph 4-107.b), and
perform operational check.
Step 4.
With battery connected and MASTER SWITCH on, measure dc voltage be-
tween positive (+) terminal of BATTERY VOLTAGE meter 1M4 and ground.
a. If voltage is good (22 to 26 vdc), go to step 9.
b.
If no voltage continue with step 5.
Step 5.
Measure dc voltage at slave receptacle. Disconnect battery.
a. If no voltage, replace battery terminal adapter (paragraph
4-261, and perform operational check.
b.
If voltage was good (22 to 26 vdc), continue with next step.
Step 6.
Check battery cables P33A1/0 (positive receptacle of battery terminal
adapter to starter shunt R2) and P44A1/ON (negative receptacle of
battery terminal adapter to dc ground stud) for continuity.
a.
If no continuity, replace cables (paragraph 4-26), and
perform operational check.
b.
If continuitv checks are good, continue with next step.
Step 7.
Check for continuity between the two large screws on shunt R2 (28 and
29, figure 4-18).
a. If no continuity, replace shunt (paragraph 4-30), and
perform operational checks.
If continuity, continue with next step.
b.
Step 8.
Remove battery charger access cover (5, figure 4-5), and disconnect
main harness connector P7 from control panel connector J7. Check for
continuity between P7-1R and shunt R2, and between J7-1L and positive
terminal of BATTERY VOLTAGE meter 1M4.
