Ignition Coil – In Vehicle Test
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in the NEUTRAL posi-
tion. Chock the wheels.
2. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning on page 1-2.
3. Using a multimeter set to 200 ohms, measure the primary coil resistance.
3.1. Disconnect both of the bullet terminals at the RPM limiter
(Figure 11-23, Page 11-23)
. 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 11-24, Page 11-24)
.
3.2. If the resistance is not between 0.6 - 1.7 ohms, bench test the ignition coil.
See Ignition Coil –
Bench Test on page 11-26.
4. Using a multimeter set to 20k ohms, measure the resistance of the secondary coil and spark plug cap
together.
4.1. Place the red (+) probe of the meter into the end of the spark plug cap that normally connects to
the spark plug and place the black (–) probe on a clean unpainted surface of the engine or frame
(Figure 11-25, Page 11-24)
.
4.2. If the resistance is between 12.0k - 14.0k ohms, the secondary coil and spark plug cap are within
acceptable limits; proceed to step 7 on page 11-26. If the resistance is not between 12.0k - 14.0k
ohms, the spark plug cap and secondary coil must be tested independently from each other.
5. Test the spark plug cap separately from the secondary coil.
5.1. Remove the rubber gasket (1) on the plug cap (2) by rolling back the gasket onto the spark plug wire
(3)
(Figure 11-26, Page 11-25)
.
5.2. Remove the cap from the wire by turning the cap counterclockwise three or four revolutions while
gently pulling it off the wire
(Figure 11-27, Page 11-25)
.
5.3. Using a multimeter set to 20k ohms, place the red (+) probe of the multimeter into the end of the
