Subaru Robin Power Products RGX3500, RGX5500, RGXI 800, RGX2400 manual Checking Field Coil

nCheck the insulation resistance between stator core and each stator lead using a Dr. Robin generator tester in megger tester mode or a megger tester. (Fig. 11-3)

If insulation is bad, replace stator with a new one.

1l-1 -3 CHECKING ROTOR

(1) CHECKING FIELD COIL

nRemove rear cover and stator.

nUsing a Dr. Robin or a circuit tester, measure the resistance of the field coil at the terminals.

NOTE I : Because a diode is soldered to the coil ends at the terminals, resistance may be measured only when tester probes touch the terminals in one combination of polarity- Therefore, if no resistance reading appears, try checking in reverse polarity.

If the resistance is not normal, replace rotor with a new one.
