ELECTRICAL SYSTEM 6-21
IGNITION COIL RESISTANCE
• Disconnect the ignition coil lead wires and spark plug cap,
and remove the ignition coil.
Measure the ignition coil resistance in both the primary and sec-
ondary windings with the multi-circuit tester. If the resistance is
not within the standard range, replace the ignition coil.

V Tester knob indication: Resistance (W)
Ignition coil resistance
Primary : 0.1 – 0.7 W (Terminal – Terminal)
Secondary : 14 – 20 kW (Spark plug cap – Terminal)
CKP SENSOR PEAK VOLTAGE
• Remove the seat. (

Measure the CKP sensor peak voltage in the following proce-
dure.
• Connect the multi-circuit tester with the peak volt adaptor as
follows.

Probe...Black/White lead wire or ground
\ 09900-25008: Multi-circuit tester set
• 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 CKP sensor peak voltage.
