4. If not previously tested, test the spark plug cap separately from the secondary coil.
4.1. Remove the rubber gasket (1) on the plug cap (2) by rolling back the gasket onto the spark plug
wire (3) (Figure 11-45, Page 11-36).
4.2. Remove the cap from the wire by turning the cap counterclockwise three or four revolutions while
gently pulling it off the wire (Figure 11-46, Page 11-36).
4.3. Use a multimeter set to 20k
Ω
(ohms) and place the red (+) probe of the multimeter into the end of
the spark plug cap that normally connects to the spark plug and place the black (–) probe into the
end of the cap with the internal screw (Figure 11-47, Page 11-37). If the resistance is not
between 4.5k - 6.0k
Ω
(ohms), the cap has failed and must be replaced. Proceed to the next step
with the spark plug cap still removed.
5. Test the secondary coil separately from the spark plug cap.
5.1. Use a multimeter set to 20k
Ω
(ohms) and place the red (+) probe of the meter into the end of the
spark plug wire and place the black (–) probe on the core (2) (Figure 11-51, Page 11-39). If the
resistance is between 6.0k - 11.0k
Ω
(ohms), the secondary coil is within acceptable limits. If the
resistance is not between 6.0k - 11.0k
Ω
(ohms), the ignition coil has failed and must be replaced.
6. If the preceding procedures indicate that the ignition coil resistance readings are within acceptable
ranges, but the coil fails to function properly, replace the ignition coil and cap.
TEST PROCEDURE 17 – KEY SWITCH (ENGINE KILL CIRCUIT)
See General Warning, Section 1, Page 1-1.
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 1-2.
3. Remove the center dash assembly. See Key Switch Removal, Section 12, Page 12-14.
4. Remove the connector from the key switch.
