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.
09900-25008: Multi-circuit tester set
Tester knob indication: Resistance (W)
Ignition coil resistance
: 0.1 – 0.7 W (Terminal – Terminal)
Primary
Secondary : 14 – 20 kW (Spark plug cap – Terminal)
CKP SENSOR PEAK VOLTAGE
• Remove the seat. (
NOTE:
Make sure all of the couplers are connected properly.
• Disconnect the CDI unit coupler 1 .
Measure the CKP sensor peak voltage in the following proce-
dure.
• Connect the multi-circuit tester with the peak volt adaptor as
follows.
CKP sensor: + Probe...Brown lead wire
- Probe...Black/White lead wire or ground
09900-25008: Multi-circuit tester set
When using the multi-circuit tester and peak volt
adaptor, refer to the appropriate instruction manual.
• 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.
