3. Set control panel system switch to
AUTO
and push
MANUAL
OVER-RIDE
to start unit.
• If spark jumps the tester gap, the ignition system
is functioning properly. The color of the spark is
not important.
• If there is no spark during this test, but there was
spark during Step 2, replace the spark plug and
test again. If still no spark, see
Single Cylinder
OHV Repair Manual #276781
for further
troubleshooting.
TEST 3 - Check Fuel Delivery System
1. Ensure that adequate fuel supply is available to
operate the system.
2. Verify that the main fuel supply valve and any in-line
fuel valves are open. Ensure that all gas appliances
are hooked up and operational.
3. Correct any fuel supply problems.
4. Reset the fault code detection system. See
Resetting
the Fault Code Detection System
.
5. Set control panel system switch to
AUTO
and push
MANUAL OVER-RIDE
to start unit.
6. If the unit still does not start, proceed to
TEST 4-
Check Fuel Supply Pressure.
TEST 4 - Check Fuel Supply Pressure
1. Turn OFF fuel valve supplying fuel to generator.
2. Remove test port plug (
A
, Figure 23). The installer
supplied test port should have been installed with the
fuel supply system during the original installation
process.
3. Install Briggs & Stratton Vacuum Tester #19495 (
B
),
in fuel supply line, as close to the generator as
possible, to verify that the fuel pressure is available
to the fuel solenoid.
Figure 23
4. Turn ON manual fuel valve.
5. Measure generator inlet fuel pressure. Fuel pressure
should measure
7-11 in.wc (LP)
or
5-7 in. wc (NG)
with all gas appliances turned on and operating.
• If the proper fuel pressure is not present, repair
or replace the fuel delivery system, then retest the
fuel pressure as described above.
• If fuel pressure is acceptable, proceed to
TEST 5-
Check Fuel Solenoid
.
TEST 5 - Check Fuel Solenoid
1. Set meter to read DC Volts.
2. Connect positive (+) test lead to wire #14, at fuel
solenoid (
A
, Figure 24).
3. Connect negative (-) test lead to ground.
4. Measure DC Volts at fuel solenoid while the engine is
cranking. No voltage will be present when the
system pauses between cranks.
Figure 24
• If no voltage is present, proceed to
Step 8
.
• If voltage is present at the fuel solenoid, proceed
to
Step 5
.
