MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
If resistance more than 2 ohms, check wire U117A16 from P17-A to TB3-19.
Repair or replace as necessary.
4.
NO ELECTRICAL POWER TO CONTROL PANEL AND DC CIRCUIT BREAKER HAS BEEN RESET.
Step 1.
Step 2.
Step 3.
Check for loose battery cable plug connector at battery.
Tighten loose connector.
Remove air baffle (paragraph 4-22a). Check for 24 Vdc at terminal board TB1-2(-) and
terminal TB1-3(+).
If 24 Vdc present, go to Step 3.
WARNING
To prevent injury, ensure that battery is disconnected
before repairing or replacing damaged wires.
If no voltage present, visually inspect for damage and perform continuity checks
on following:
P103C00 (TB1-4 to bulkhead connector)
V102H00 (TB1-2 to bulkhead connector)
P103A00 (bulkhead connector to P20(+))
V102AJ00 (bulkhead connector to P20(-))
Replace wires if damaged or no continuity.
Ensure that DC CIRCUIT BREAKER is reset. Check for 24 Vdc between DC CIRCUIT
BREAKER pin 2(+) and terminal board TB3-2(-).
If 24 Vdc present, go to Step 4.
If no voltage, check for 24 Vdc between DC CIRCUIT BREAKER pin 1(+) and
terminal board TB3-2(-). If voltage present, replace DC CIRCUIT BREAKER
(paragraph 4-78b). If no voltage, visually inspect for damage and perform continu-
ity check on wires P103E14 (20 amp shunt R1-A to TB3-4), P103B14 (20 amp
shunt R1-B to TB1-3), and V012J18 (TB3-2 to TB1-2). Replace wires if damaged
or no continuity.
