IGNITION COIL RESISTANCE
• Disconnect the ignition coil lead wires and plug cap.
Measure the ignition coil resistance in both the primary and sec-
ondary windings. If the resistance is not within the standard
range, replace the ignition coil with a new one.
# 09900-25008: Multi circuit tester set
( Tester knob indication: Resistance (Ω)
& Ignition coil resistance
: 1.6 – 2.7 Ω Ω Ω Ω ( + + + + terminal – - - - - terminal)
Primary
Secondary: 18 – 26 kΩ Ω Ω Ω (Plug cap – + + + + terminal)
PICK-UP COIL PEAK VOLTAGE
• Remove the right frame cover. (!5-3)
• Disconnect the wire harness coupler 1 at the ignitor.
NOTE:
Make sure that all of the couplers are connected properly and
the battery is used in fully-charged condition.
Measure the pick-up coil peak voltage in the following proce-
dures:
• Connect the multi circuit tester with peak volt adaptor as fol-
lows.
+ Probe: Blue lead wire
- Probe: Black/White lead wire

Before using the multi circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruction
manual.
