TROUBLESHOOTING AND ELECTRICAL SYSTEM:
KEY-START WITH NEUTRAL REV GAS VEHICLE
Test Procedures
11
TEST PROCEDURE 15 – RPM Limiter
See General Warning on page 1-1.
1.
Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in the NEUTRAL position.
Chock the wheels.
2.
Disconnect battery and spark plug wire(s).
See Disconnecting the Battery – Gasoline Vehicles, Section
3.
Disconnect both of the bullet terminals
.
4.
Using a multimeter set to 200 ohms, place the red (+) probe on the brown ground wire and place the black (–)
probe on one of the black wire female bullet connectors. The reading should be no continuity. If the reading
is not correct, replace the RPM limiter.
5.
This test will find most bad RPM limiters. Some of them may bench test okay but fail under a load due to heat
while operating. Another method of testing is to replace the RPM limiter and then run the engine. If the engine
runs properly, keep the new RPM limiter in the circuit.
TEST PROCEDURE 16 – Ignition Coil
See General Warning on page 1-1.
The following test procedures will properly detect a coil that has failed in most cases; however, in rare cases, some
ignition coils can fail to operate at normal (warmer) operating temperatures. If the ignition coil has tested okay in
the vehicle and on the bench, but fails to operate reliably, replace the coil with a known good coil and operate the
engine for several minutes to ensure that the coil functions at normal operating temperature. If the new coil functions
properly, keep the new coil in the circuit.
