Electrical Troubleshooting (Contd)
MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
NOTE
Battery voltmeter located on instrument panel is not always
accurate and should not be used to adjust voltage. Indicator
needle in voltmeter located on instrument panel should cover the
white dot at edge of green area when battery voltage is
28.0 0.2 Vdc.
If voltage across batteries cannot be adjusted to 28.0 0.2 Vdc, go to malfunction 5, test 3
and check voltage.
END OF TESTING!
7. BATTERIES HOT OR BOILING, CORRECTED SPECIFIC GRAVITY OF ALL CELLS IS 1.280
NOTE
If STE/ICE-R is available, perform NG50 Charging Circuit Tests
Test charging voltage (malfunction 5, test 2).
END OF TESTING!
8. BATTERIES USE EXCESSIVE WATER
NOTE
If STE/ICE-R is available, perform NG81 Battery Test or NG50
Charging Circuit Tests (WP 0017 00).
NOTE
If STE/ICE-R is available, perform NG81 Battery Test or NG50
Charging Circuit Tests (WP 0017 00).
9. BATTERIES RUN DOWN IN OPERATION
NOTE
If STE/ICE-R is available, perform NG50 Charging Circuit Tests
Test 1. Check for loose or missing fan drivebelt.
Adjust or replace fan drivebelt (WP 0084 00).
Test 2. Test charging voltage (malfunction 5, test 2).
NOTE
If proper voltage is indicated, problem is not in charging system.
Refer to battery system troubleshooting (malfunction 1).
END OF TESTING!
CHARGING SYSTEM (100 AMP)
10. NO ALTERNATOR OUTPUT (BATTERY GAUGE IN LEFT-HAND RED)
NOTE
If STE/ICE-R is available, perform NG50 Charging Circuit Test
Test 1. Check for loose alternator mounting or missing drivebelt.
a. Tighten loose mounting hardware.
b. Replace missing drivebelt (WP 0084 00).
Test 2. Test charging system output voltage.
