BY-PASSING THE OVERSPEED BOARD
An
unwanted shutdown or if the engine runs 10-15 seconds
and then shuts down can be caused by a faulty over-speed
board.
1. Refer
to
the Wtting Diagram in this manual.
2. Unplug the brown #6 wire that connects between pin #12
of the 15 pin plug connector and the ignition module. The
wire
plug connection is in the harness between the two
components.
3. Without unplugging any connections on the coil relay,
· place a jumper between connection #30 and #87.
4. Manually controlling #30 and #87, start the engine
physically controlling the actuator/throttle keeping the
engine speed at a low comfortable range. H the engine
continues to run more than 15 seconds, a faulty overspeed
board
exists.
NOTE:
The above should only be perfonned as a test. The
generator with a by-passed overspeed board should not be
run under nonnal use. This can present a hazard.
