TEST . . .
1. Start and run engine at 1000 to 1200 rpm (high idle)
2. Set voltmeter switch
to 10-volt position
3. Turn rheostat knob
slowly clockwise until ammeter
reads 20 amperes
4. Now look at voltmeter
. It should not indicate more than 0.1 volt
5. Set switch
to the 1-volt position for a more accurate reading
6. Place switches and knobs in OFF position. Move black
voltmeter cable C2 from generator frame and ground
to regulator frame. With ammeter
showing 20
amperes again, voltmeter
should not read more than 0.1 volt
7. If voltmeter
shows more than 0.1 volt on either test,
look for loose generator or regulator mount, a loose,
corroded, or bad battery to ground cable
