3. TROUBLESHOOTING

To check if the lighting system is working properly, use the meter to check the voltage.
Regulator output data:
Perform these checks with the regulator and the magneto connected.
• The A.C. voltage (Yellow cable) should be I3.8 to 14.5V. at 6,000 R.P.M. (meter in A.C.
position).
If the above parameters are not fulfilled, the alternator must be checked.
Checking the alternator:
Disconnect all the cables from the magneto and check the resistance according to the
enclosed table.

The first step is to disconnect the green stop light cable on the cdi coil and check if
there is a spark.
If the problem persists, each ignition system component should be checked one by one.
Before starting to check components, check that the connections are clean and well connected and
the wiring is in good condition.
