7-3 MEASURING INSULATION RESISTANCE
● CONTROL PANEL
Connect a megger tester to one of receptacle out-
put terminals and the ground terminal, then mea-
sure the insulation resistance.
An insulation resistance of 1 megohm or more is
normal. (The original insulation resistance at the
time of shipment from the factory is 10 megohms or
more.)
If it is less than 1 megohm, disassemble the gener-
ator and measure the insulation resistance of the
stator, rotor and control panel individually.
● STATOR
(1)
Measure the insulation resistance between
BLUE lead and the core.
(2) Measure the insulation resistance between
WHITE lead and the core.
(3) Measure the insulation resistance between
YELLOW lead and the core.
(4) Measure the insulation resistance between
BROWN lead and the core.
● ROTOR
Measure the insulation across one of the soldered
terminals of the rotor and the core.
Any part where the insulation resistance is less than 1 M
Ω has faulty insulation, and may cause electric
leakage and electric shock.
Replace the faulty part.
