Onan Motor Generator
motor generator receptacle. Both of these com-
ponents are located in the external utilities com-
partment on the left side of the vehicle . Be sure
the crankcase has been filled with oil to the "F"
full mark on the dipstick. Check oil only when
the motor generator is not operating.
The remote START-STOP switch is a three-
position rocker switch. By pressing the top half
of the switch the starter on the motor generator
will be activated, hold in the switch until the
unit is started. The switch should then be re-
leased . When the motor generator is running the
small amber light next to the switch will be lit.
To stop the unit depress the bottom half of the
switch, and hold in until the unit comes to a full
stop. The START-STOP switch on the unit itself
operates in a similar manner.
IMPORTANT : If the motor generator has been
running with a load connected, disconnect the
load and allow it to run for a few minutes (with
no-load connected) before pushing STOP button .
The circuit breaker on top of the unit will trip
when the demand for electricity in amperes ex-
ceeds the motor generators capabilities. If the
circuit breaker does trip, remove part of the
electrical load and reset the breaker .
HOUR METER
Located to the left of the START-STOP
switch is the HOUR METER. The HOUR-
32
METER indicates total amount of hours motor
generator has operated. This gauge will aid in
determining when the motor generator should
receive periodic inspections, maintenance and
service parts replacements in conjunction with
the Maintenance Schedule folder.
HIGH TEMPERATURE OPERATION
Make sure that nothing obstructs air flow to
and from the unit.
Keep cooling fins clean. Motor generator
housing should be unaltered and undamaged .
LOW TEMPERATURE OPERATION
1 . Use correct SAE No. Oil for temperature
conditions
(see SERVICE AND MAINTE-
NANCE section later in this manual to deter-
mine proper weight oil) . Change oil only when
engine is warm.
2 . Keep fuel system clean and battery in well
charged condition.
LOW OIL LEVEL
If motor generator suddenly stops during a
tight turn or sudden stop of the MotorHome, the
cause is most likely a low oil level . The unit is
designed to shut-down when oil level is ab-
normally low. Before attempting to restart unit,
check oil level and correct as necessary .
DUSTY AND DIRTY OPERATION
1. Keep unit clean . Keep cooling system
clean.
FUEL
2 . Service air cleaner as required .
3 . Change crankcase oil and filter more often
than normal .
4 . Keep governor linkage clean.
'The motor generator's fuel is supplied from
the vehicle's main fuel tank .
NOTE: The motor generator may be operated
while the vehicle is underway . However, the
vehicle's gasoline supply will be depleted at a
faster rate .
