6-22 ELECTRICAL SYSTEM
• Shift the transmission into the neutral, and then turn the igni-
tion switch to the "ON" position.
• Squeeze the clutch lever.
• Press the starter button and allow the engine to crank for a
few seconds, and then measure the pick-up coil peak voltage.
• Repeat the above procedure a few times and measure the
highest peak voltage.
' Tester knob indication: Voltage (%
& Pick-up coil peak voltage: More than 2.0 V
If the peak voltage is lower than the specified values, check the
peak voltage at the pick-up coil lead wire coupler.
• Remove the seat. (!5-3)
• Remove the fuel tank. (!4-2)
• Disconnect the pick-up coil lead wire coupler and connect the
multi circuit tester with the peak volt adaptor.
+ Probe: Blue lead wire
- Probe: Green lead wire
Measure the pick-up coil peak voltage at the pick-up coil lead
wire coupler in the same manner as on the ignitor coupler.
' Tester knob indication: Voltage (%
& Pick-up coil peak voltage: More than 2.0 V
If the peak voltage on the pick-up coil lead wire coupler is OK
but on the ignitor coupler is out of specification, the wire harness
must be replaced. If both peak voltages are out of specification,
the pick-up coil must be replaced and re-checked.
PICK-UP COIL RESISTANCE
Measure the resistance between the lead wires and ground. If
the resistance is not as specified, the pick-up coil must be
replaced.
