IGNITION COIL PRIMARY PEAK
VOLTAGE INSPECTION
Remove the frame coverand fuel tank.
Disconnect the spark plug caps.
With the spark plug cap connected, place a new spark plug
on the engine to ground it.

❖ Check that all the couplers are connected.
❖ Check that the battery is fully charged.
Measure the No.1 and No.2 ignition coil primary peak
voltage using the tester in the following procedure.
Connect the tester as follows.
Ignition coil
Probe : BY lead wire terminal
Probe : Ground
N O T E
Do not disconnect the ignition coil / plug cap lead wire
couplers.
Shift the transmission into the neutral and then
turn the ignition switch to the “ON” position.
Squeeze the clutch lever.
Press the starter switch and allow the engine to crank for a
few seconds, and then measure the ignition coil primary
peak voltage.
Repeat the above procedure a few times and measure the
highest ignition coil primary peak voltage.

While testing, do not touch the tester probes and spark
plugs to prevent receiving an electric shock.
If the peak voltage is lower than the specified values, inspect
the ignition coil.
IGNITION COIL RESISTANCE
INSPECTION
Remove the fuel tank.
Disconnect the ignition coil read wire.
Measure the ignition coil resistance in bolt
the primary and secondary windings. If the
resistance is not within the standard range,
replace the ignition coil with a new one.
