TROUBLESHOOTING AND ELECTRICAL SYSTEM: FE400 ENGINE
Test Procedure 15 – RPM Limiter, Continued:
3. Disconnect both of the bullet terminals (Figure 11-42, Page 11-34).
4. Use a multimeter set to 200 Ω (ohms) and 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, Section 1, 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 tempera-
ture. If the new coil functions properly, keep the new coil in the circuit.
Ignition Coil – In Vehicle Test
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in NEUTRAL. Chock
the wheels.
2. Disconnect the battery cables as instructed (Figure 11-1, Page 11-5). See WARNING "To avoid unin-
tentionally starting..." in General Warning, Section 1, Page 1-1.
3. Use a multimeter set to 200 Ω (ohms) and measure the primary coil resistance.
3.1. Disconnect both of the bullet terminals at the RPM limiter (Figure 11-42, Page 11-34). Place the
red (+) probe of the meter on the male bullet terminal of the wire connecting to the ignition coil
under the fan housing, and place the black (–) probe on a clean unpainted surface of the engine
or frame (Figure 11-43, Page 11-35).
3.2. If the resistance is not between 0.6 - 1.7 Ω (ohms), bench test the ignition coil. See Ignition Coil
– Bench Test on page 11-37.
