11-1 NO AC OUTPUT

11-1-1 CHECKING CONDENSER

(1) Check the capacity of condensers using a “Dr. Robin” generator tester in capacitance meter mode.

NOTE : Be sure to discharge condensers by shorting condenser leads each other before checking their capacitance, or the accurate reading cannot be obtained.

	Table. 11-1

(2)If such an instrument is unavailable, the condenser can be checked by replacing with a new one. If the generator performs good with new condenser, the cause of trouble is defect in original condenser.

11-1-2 CHECKING STATOR

(1)Remove control panel and disconnect stator wires at the connectors.

(2)Measure the resistance between terminals on stator leads. (See Fig.11-2) Refer to Table 9-1 for normal resistance.

If stator is faulty, replace it with a new one.
