voltmeter switch is in 4 volt position.
5, Slowly increase engine speed from idle to
1,500 R.P.M. while observing the voltmeter. Volt
meter reading should be less than .1 volt if
regulator ground circuit is satisfactory.
NOTE: Increase engine speed momentarily
to see if the generator charges after the jumper
lead is removed If the generator charges with
the jumper lead on, but will not charge after
the jumper lead is removed, the most common
causes are: Cutout relay set too high, voltage
regulator set below closing voltage of the cut
out relay, or a defective field circuit in the
regulator.
