IGNITION COIL RESISTANCE
• Remove the fuel tank. (6-3)
• Remove the frame head covers. (3-3)
• Disconnect the spark plug caps.
• Measure the ignition coil resistance in both the primary and
secondary windings. If the resistance is not within the stan-
dard range, replace the ignition coil with a new one.
 Ignition coil resistance
Primary: 2 – 6 Ω (+ terminal – - terminal)
Secondary: 15 – 30 kΩ (Plug cap – + terminal)
 09900-25008: Multi-circuit tester set
 Tester knob indication: Resistance (Ω)
CKP SENSOR PEAK VOLTAGE
• Remove the right frame cover. (8-4)
NOTE:
Be sure that all couplers are connected properly and the battery
used is in fully-charged condition.
• Disconnect the ECM coupler 1.
• Connect the multi circuit tester with peak volt adaptor as fol-
lows.
• Insert the needle pointed probes to the ECM coupler.
• Measure the CKP sensor peak voltage between Green/Yel-
low and Yellow/Brown lead wires at the ECM coupler.
Green/Yellow (+ Probe) – Brown (- Probe)
 09900-25008: Multi circuit tester set
09900-25009: Needle pointed probe set

Before using the multi circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruction
manual.
