SIGNAL GENERATOR PEAK VOLTAGE
• Remove the luggage box. (!5-2)
NOTE:
Be sure that all couplers are connected properly and the battery
used is in fully-charged condition.
• Connect the multi circuit tester with peak volt adaptor as fol-
lows.
• Measure the signal generator peak voltage between White and
Green lead wires at the ignitor coupler.
Bl/B (+ Probe) – Green (- Probe)

When using the multi circuit tester and peak volt adap-
tor, follow the instruction manual.
• Shift the transmission into the neutral and turn ignition switch
"ON".
• Crank the engine a few seconds with the starter motor by de-
pressing starter button and check the signal generator peak
voltage.
• Repeat the above test procedure a few times and measure
the highest peak voltage.
# Signal generator peak voltage:
If the peak voltage is lower than the standard range, check the
peak voltage at the signal generator lead wire coupler.
• Remove the luggage box. (!5-2)
• Disconnect the signal generator lead wire coupler and con-
nect the multi circuit tester with the peak volt adaptor.
Blue (+ Probe) – Green (- Probe)
• Measure the signal generator peak voltage at the signal gen-
erator lead wire coupler.

# Signal generator peak voltage:
If the peak voltage is lower than the standard range, check each
coupler at both ends of the circuit or replace the signal genera-
tor and inspect it again.
