POSSIBLE
CAUSE
I.
Fuel level is low or oil level
is low.
!.*Faulty choke operation due
to
sticking choke linkage,
incorrect choke adjustment,
open circuit in wiring between
choke heater and generator, or
defective choke heater.
3.*Vapor lock due
to:
a.high ambient air temperature
b.faulty fuel pump
4.
Contaminated or incorrect fuel.
*Gasoline sets only
1.
Weak or discharged battery.
Generator set charger will not
recharge a battery that is in
a very low state of charge.
2. Load connected to battery
while set is turned
off.
3. Disconnect the negative
(-)
battery cable at the battery
and remove lead marked F1-1
to
CR2-C from control fuse
F1
terminal
1.
Connect a DC
ammeter and
a
5-ampere fuse
in series between control fuse
F1,
terminal 1, and the disconnected
lead marked F1-1
to
CR2-C.
Reconnect battery negative
(-)
cable. With set
running, the ammeter should
read between
0
to
1
ampere.
If
meter shows battery is discharging,
fault is due
to:
a. defective generator charge
winding
b.
defective diode CR2
c. defective resistor
R1
~
CORRECTIVE ACTION
1.
Check fuel and oil level and refill
as necessary.
2.
Refer to Fuel System section for
testing and service procedures.
3a. Remove any objects or debris that
may restrict airflow.
3b.
Refer
to
Fuel System section for
testing and service procedures.
4.
Refill tank with fresh fuel.
1.
Connect a separate battery charger to
bring battery up to full charge.
2.
Turn
off
load.
3a. Refer to Generator section
for
3b. Test CR2 diode and replace
if
3c. Test resistor
