(1) Measure insulation across one of the solder terminals and the core of the rotor.
(2) Measure between stator leads as follows: BLUE lead and core; WHITE lead and core;
YELLOW lead and core: and BROWN lead and core.
WARNING: DO NOT USE ANY PART WITH INSULATION RESISTANCE OF LESS THAN 1 MΩ
ΩΩ
Ω.
LOW INSULATION RESISTANCE IS AN INDICATION THAT THE PART IS FAULTY
INSULATION AND MAY CAUSE ELECTRICAL LEAKAGE AND POTENTIALLY
FATAL ELECTRICAL SHOCK. REPLACE ALL FAULTY PARTS.
5-5 Troubleshooting Charts
(1) This section provides the instructions for generator checkout and fault isolation. The
troubleshooting procedures are presented in Table 5-2. The table lists typical faults, presents
probable cause, and provides the remedy for the majority of generator operational faults.
