11-4-6 CHECK THE DC COIL

Check the resistance between two brown leads from stator with a circuit tester.

MODEL		SPECIFICATION	RESISTANCE

RGV2800	60 Hz	120V, 120V/240V	0.25 Ω

RGV4100	60 Hz	120V, 120V/240V	0.18 Ω

RGV6100	60 Hz	120V, 120V/240V	0.13 Ω

		Table. 11-3

If the resistance reading is much larger or smaller than the specified value, the DC coil of the stator is faulty. Replace stator with a new one.

11-5 IDLE CONTROL

11-5-1 ENGINE SPEED IS NOT INCREASED WHEN A LOAD IS APPLIED

(1)Inspect the solenoid bracket. Check the bend angle of solenoid bracket. If the bracket is dis- torted, correct the angle with proper tool.

(2)Check the wattage of load applied to the gen- erator. If the generator is loaded over the rated wattage, the engine speed can not be in- creased. Most induction loads such as elec- tric motor or electric tools or welding machine require three to five times large wattage of their ratings at starting. This starting wattage must not exceed the rated output of the generator.

(3)Check the slow set r.p.m.

The normal idling speed by the IDLE CON- TROL is as follows :

RGV2800 .................. 1900 to 2100 r.p.m. RGV4100, 6100 ........ 2000 to 2200 r.p.m.

The above speed setting is for cold engine con- dition. If the engine speed is out of adjusting range of the adjusting screw, move the sole- noid backward.
