reads below this value, refer to the appropriate
generator technical manual for generator
troubleshooting instruction. A correct reading
on the voltmeter indicates that the current
regulator may be at fault. To check the
regulator, turn the regulator control switch to
the OFF position.
Disconnect the output
connectors from the lighting circuit and
connects an alternating current ammeter of
proper range directly across the output. Refer
to the appropriate generator technical manual
for ammeter access instructions. Adjust the
regulator for full brightness. If the ammeter
reads approximately 6.6 amperes, the
regulator is operating satisfactorily and the
probable cause will be found in item number 2
below. If the ammeter reads low or high or
fails to read at all, check the leads from the
connections. If the ammeter still reads an
incorrect value, check the appropriate current

and/or damaged cables.
The open circuit voltage of the regulator and
at the ends of a broken cable can be in excess 'j
of 300 volts. Handle and repair portions of the
series circuit proper in the voltage off condition
