\lo peak voltage
Peak voltage is normal, but
no spark j ; mps at plug.
Low peak voltage
No peak voltage.
Low peak voltage.
No peak voltage.
Probable Cause (Check in numerical order)
0
lncorrect peak voltage adaptor connections. (system is normal if
measured voltage is over the specifications with reverse connections.)
@
The multimeter impedance is too low.
O
Cranking speed is too slow.
Battery is undercharged (or operating force of the kickstarter is
weak).
@ The sample timing of the tester and measured pulse were not
synchronized. (System is normal if measured voltage is over the
standard voltage at least once.)
O
Poorly connected connectors or an open circuit in ignition system.
8
Faulty ignition system control circuit such as side as stand switch
or reverse switch circuit (for appropriate models only).
O
Faulty exciter coil. (Measure the peak voltage.)

@ Battery is undercharged. (Voltage drops largely when the engine is
started-only for DC-CDI)
@ Short circuit i n engine stop switch wire (except DC-CDI).
@
Faulty ignition switch or engine stop switch.
@ Loose or poorly connected ignition control module connector(s).

Open circuit or poor connection in ground cord of the ignition control
module.
