is different from a conventional receptacle. In the
event of a ground fault, the GFCI will trip and
quickly stop the flow the flow of electricity, to
prevent serious injury. A ground fault is defined as
a condition where electricity does not follow its
normal path, but passe s through a person’s body
to reach ground. A defective power tool can cause
a ground fault.
The GFCI receptacle designation is a NEMA 5-
20R, and will accept either a NEMA 5-15P or a
NEMA 5-20P electrical plug. This receptacle is
powered from a separate circuit-not the generator,
and will not work during a utility power outage.
This receptacle is rated for 125 volts at 20 amps
and will power most portable hand tools.
Reference 23: GFCI Test Button . This button
tests the operation of the GFCI receptacle. When
pressing the TEST button, the receptacle will trip.
Then press the reset button to reactivate the
GFCI. Test the GFCI receptacle every month.
Reference 24: Circuit Breaker
. A 125-volt, 20-
amp push to reset circuit breaker protects the
GFCI receptacle. If this circuit breaker trips, the
black center post will be extended. Allow the
circuit breaker to cool for 1 minute and press the
black post beak into the housing.
Reference 25: GFCI Reset Button . If the GFCI
trips, press the reset button to reactivate the
receptacle.
Section 4
Theory of Operation
When starting the 165952A generator in manual
mode (Section 3, Reference 17), the following
sequence of events occur:
1 : 12 volts (dc) is delivered from the battery “+”
terminal on the engine starter to the on/off/auto
three position switch located on the control panel
via lead wire “012” which is located inside the
engine wiring harness.
2
: If the three position switch is in the manual
mode, 12 volts (dc) is then delivered to the system
control board which is located inside the control
box via lead wire “01A”.
3
: Simultaneous to delivering 12 volts via lead wire
“01A” the three position switch closes a circuit
between lead wires “06A and 07”. The closure of
lead wires “O6A and O7” tells the system
controller to send 12 volts (dc) to the engine start
solenoid via lead wire “O3”. Lead wire “O3” is
located inside the engine wiring harness.
Trouble Shooting Hint : When the system control
board inputs (leads “O7 and O6A”) are connected
together, the engine will attempt to start if 12 volts
is present between lead wires “01A” and “G2B”.
System Control Board
4
: At the same time the engine is cranking, both
the LP/NG fuel lock off valve and compartment fan
are energized by 12 volts via lead wire “O4”. Lead
wire “O4” exits the control box inside the engine
wiring harness.
5
: As the engine cranks, the pistons create
vacuum. The vacuum will influence the secondary
gas regulator to open and allow fuel to flow. The
secondary regulator reacts to a minimum of 4
ounces per square inch of vacuum.
Trouble Shooting Hint : It is crucial to have both
correct gas inlet pressure and fuel mixture for
quick starting. There is a 1/8” NPT port on the side
of the regulator that provides a convenient point to
measure inlet pressure.
6
: As the engine comes up to operating speed
(3600 rpm), the engine continually sends an
electrical signal through a black with red stripe
lead wire that exits the engine. The black with red
stripe lead wire is connected into lead wire “O5A”.
Lead wire “O5A” is located inside of the engine
wiring harness and terminates at the system
control board. The importance of this signal is that
once a stable frequency is measured from the
magneto, the system control board takes the
engine starter off line. Secondly, if the frequency
exceeds 4080rpm for a time interval of 5 seconds
or greater, the system control board will alarm and
shutdown the engine down as a result of an over
speed condition.
7
: During start up, the control board disregards low
oil pressure for 15 seconds. If after that period of
time, oil pressure has not developed, the system
control board will alarm and shut down the engine
as a result of low oil pressure.
