Test Procedures
TROUBLESHOOTING AND ELECTRICAL SYSTEM:
KEY-START WITH NEUTRAL REV GAS VEHICLE
WARNING
• When the white/black engine kill wire is disconnected, the engine will not stop running after the key
switch is turned to the OFF position. It will be necessary to pull and hold the choke handle until the
engine stops running.
4.
If the engine does not run, connect the white/black wire at the bullet connector next to the RPM limiter and
proceed to Test Procedure 14 – Ignition Spark on page 11-22.
TEST PROCEDURE 14 – Ignition Spark
See General Warning on page 1-1.
NOTE:
Keep the battery connected while performing this test procedure.
1.
Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in the NEUTRAL position.
Chock the wheels.
2.
Remove the plug wire from the spark plug. Using an ignition spark gap test tool (Thexton 404
®
or equivalent),
check for correct spark
.
2.1. Adjust the tester probes to approximately to 18,000 volts (18 Kv) setting (SE –
Small Engine Setting
on the Thexton 404 tool). Connect the tester to the spark plug wire, and connect the alligator clip to
a solid engine ground.
2.2. Start the engine. There should be a strong blue spark between the probes of the spark gap tester. If there is
no spark, or if the spark is a faint yellow or red color, test components of the ignition circuit.
3.
If the spark gap tester tool indicates a strong blue spark, it is possible the spark plug has failed internally. Check
the spark plug gap. The gap should be set at 0.027 to 0.031 of an inch (0.69 to 0.79 mm). If the gap is correct,
replace the spark plug with a new part and test the engine for proper operation.
