HIGH RPM SHUTDOWN SWITCH
DESCRIPTION
An overspeed switch in the DC circuit shuts off the
generators engine by grounding out the ignition system if
the engine's speed reaches 2175 rpm (approximately).
After correcting the problem, this switch can be reset by
momentarily depressing the stop switch. Refer to the
WIRING DIAGRAMS in this manual.
If the overspeed switch is faulty, (resetting with the stop
switch fails to reset the circuit), lift the white/yellow wire
off the T5 terminal and connect
it
with the redJpurple wire
on the T4 terminal. Now restart the generator.
If this bypa8.s is successful, replace the faulty overspeed
switch.
NOTE:
Overspeed switches draw a small amount of amperage
(25 milliamps) at all times once the generator is connected
to its starting battery. This amounts to approximately 18
amp-hours in a month. It is not necessary to be concerned
with this slight amperage draw during normal seasonal
operation. However,
if
the generator set is to be unused for
i
many months, it is best to either remove the
8
amp ignition
I
fuse from the control panel on the generator or tum off the
generator's starting battery switch.

CAUTION:
It is very important that the overs peed
shutdown always be installed and functioning. Any
tampering with the overs peed shutdown module, which
would cause it to malfunction. could be
a
cause of
injury should the generator's belt-driven governor fail
and cause the generator to run away.
