IGNITION COIL INSPECTION

CONTINUITY TEST
Remove the front fender. (Refer to the
chapter 2)
Remove the spark plug cap. (Refer to the
chapter 6)
Disconnect the ignition coil wires.
This test is to inspect the continuity of
ignition coil.
Measure the resistance between the ignition
coil primary coil terminals.
Resistance: 3.4～4.1Ω/20◦C
Remove the spark plug cap and measure the
secondary coil resistance between the spark
plug wire and the primary coil terminal.
Resistance:
(with plug cap): 19.8KΩ/20◦C
(without plug cap): 14.45KΩ/20◦C
This test is for reference only. Accurate
test should be performed with a CDI
tester.
Measure the spark plug cap resistance.
Remove the spark plug cap and measure the
spark plug resistance.
Resistance: 4.2～5.2KΩ/20◦C
Measure the resistance in the XKΩ range
of the electric tester.
