Subaru Robin Power Products R1300 manual Measuring Insulation Resistance

8-4 MEASURING INSULATION RESISTANCE

Use a “Dr. Robin”generator tester in megger tester mode or use a megger tester to check the insulation resistance. Connect a megger tester to one of recep- tacle output terminals and the ground terminal, then measure the insulation resistance. An insulation re- sistance of 1 megohm or more is normal. (The original insulation resistance at the time of shipment from the factory is 10 megohm or more.)

If it is lessthan 1 megohm, disassemble the gener- ator andmeasure the insulation resistance of the stator, rotor and control panel individually.

0STATOR

(1) Measurethe insulation resistance between BROWN lead and the core.

(2)Measure the insulation resistance between YEL- LOW lead and the core.

(3)Measure the insulation resistance between

-BLACK leadand the core.

0ROTOR

Measure the insulation acrossone of the soldered terminals of the rotor and the core.
