TEST PROCEDURE 15 – 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.
Ignition Coil – In Vehicle Test
1. Disconnect battery and spark plug wire(s). See Disconnecting the Battery – Gasoline Vehicles, Section
1, Page 1-3.
2. Using a multimeter set to 200 ohms, measure the primary coil resistance.
2.1. Disconnect both of the bullet terminals at the RPM limiter (Figure 12-19, Page 12-22) . 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
12-20, Page 12-23) .
2.2. If the resistance is not between 0.6 - 1.7 ohms, bench test the ignition coil.
