FAULT	PROBABLE CAUSE		REMEDY
No AC output.		8.	Check insulation resistance between the
			stator core and each stator leads. Check
			using a megger tester. Replace the stator if it
			fails the megger test.
	Rotor fault.	1.	Check rotor.
		2.	Remove generator rear cover and stator
			(refer to COMPONENT REPLACEMENT for
			procedures).
		3.	Using a multimeter, measure field coil
			resistance. Measure resistance at the
			soldered terminals of the rotor and the core.
		NOTE: Because a diode is soldered to the coil
		ends at the terminals, resistance may be
		measured only when the multimeter probes touch
		the terminals in one combination of polarity.
		Therefore, if no resistance reading appears, try
		checking in reverse polarity.
		4.	Using a megger tester, check insulation
			resistance between the soldered terminal and
			the stator core.
		5.	Replace rotor if it does not meet the
			resistance values in Table 6.
