3. Checking the insulation resis-
tance between the pr imary ter-
minal and the coil case.
(Megohmmeter 500 volt)
Normal resistance: 10 megohms +
The coil should be replaced
should it not meet the resis-
tance values given above.
Checking Overspeed Module
1. with gener ator running, manually move the throttle lever to full
open. Generator set should stop.
2. Depress ON and START switches. Generator should not start.
3. Depress STOP switch to reset overspeed module circuit.
depress ON and START~ the generator should start properly.
Then
4. To bypass the overspeed module to check safety circuit, disconnect
the black with white stripe wire from the distributor at the con-
nector in the harness. Use a jumper wire to connect this to the
B+ of the coil. Remove all four wires from the overspeed module,
ensuring that they do not touch each other or ground.

SAFETY WARNING:
Over speed module MUST be proper ly reconnected and
functioning BEFORE operating generator.
The voltmeter in the remote instrument panel can be a useful instru-
ment in determining the status of your electrical system and warn you
when an abnormality occurs. The voltmeter will indicate differently,
depending when the readings are taken.
Fully charged batteries that are in a static state should read between
12.3 and 12.6 volts on the dial. The term static means that the bat-
tery has not been charged or discharged for at least 2 hours. If the
reading is between 11 and 11.5 volts, then the battery is about half
discharged and should be charged to insure its usefulness. If the
engine is started and the needle does not go up, this would indicate
that no charge is being delivered to the battery.
When the battery is being charged, the needle should be between 12.6
and 13 vol ts • The needle may move up to about the 14.6 volt range
toward the end of the charge cycle, at which time the needle drops
back to the 12.6 to 13 volt range, as voltage regulation controls this
function. If the battery voltage exceeds 15 volts, this indicates
