(3)Check the insulation resistance between sta- tor 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.

11-1-3 CHECKING ROTOR

(1) Remove rear cover and stator.

(2) Using a Dr. Robin or a circuit tester, measure
the resistance of the field coil at the terminals.						Fig. 11-4
					( Ω)

	MODEL	RGV2800	RGV4100	RGV6100

	RESISTANCE	1.75 Ω	1.77 Ω		1.60 Ω

Table. 11-2

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

[Remedy]

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