8-20 ELECTRICAL SYSTEM
IGNITION COIL RESISTANCE
• Remove the left front inner fender. (7-5)
• Disconnect the ignition coil lead wires and spark plug cap,
and remove the ignition oil.
Measure the ignition coil resistance in both the primary and sec-
ondary windings using the multi circuit tester. If the resistance in
both the primary and secondary windings is close to the speci-
fied values, the windings are in sound condition.

Tester knob indication: Resistance (Ω)
Ignition coil resistance
Primary : 0.05 – 1.0 Ω (+Terminal – -Terminal)
Secondary : 10 – 20 kΩ (Spark plug cap – +Terminal)
PICKUP COIL PEAK VOLTAGE
NOTE:
Make sure all of the couplers are connected properly.
• Disconnect the CDI unit coupler 1.
Measure the pickup coil peak voltage in the following procedure.
• Connect the multi circuit tester with the peak volt adaptor as
follows.
Pickup coil: + Probe...Green/White lead wire
- Probe...Black/Yellow lead wire

• Shift the transmission to the neutral position, turn the ignition
switch to the “ON” position.
• Press the starter button and allow the engine to turn for a few
seconds, and then measure the pickup coil peak voltage.
