GENERAL
CAUTION
When troubleshooting
a generator
set, always consider
the
simplest
causes first.
Narrow
the problem
down
to a func-
tional
system, such as fuel or ignition.
To operate efficient-
ly,
an engine
must
have sufficient
fuel,
a good
ignition
spark
and
good
compression.
All
adjustments
must
be
correct.
For a generator
to produce the required
electricity,
all parts must be clean, all connections
tight,
and all com-
ponents
in working
order. See Table 4-l
for Engine Trou-
bleshooting
and Table 4-2 for Generator
Troubleshooting.

RV SYSTEMS
CHECK
The "RV
Systems Check"
is designed to check the electri-
cal status of an RV generator
set prior to connecting
and
testing
with the controller.
If the generator
does not check
out in each step, correct the malfunction
before proceeding
to the next step.
Do not push the V.B.U.
button
after the "GEN
ON"
lamp is on. Voltage
regulator
damage may
resu It.
CAUTION
Do not use the RV Systems Check as a replace-
ment for the controller.
The hi-temp
and low
oil pressure switches will not shut the machine
down
in the event of a malfunction.
Generator
damage will result.
1. Make sure the battery
is properly
connected
and oil is
at proper level.
CAUTION
Do not push the CRANK
button
after the en-
2. Check
the three fuses in the RV Systems Check tester
gine is running.
Starter damage will result.
(Figure 4-l).
Replace any blown fuses.
