Make sure that the battery connections are free of corrosion and tight. If that' s ok then:

1) Check to see if the charging circuit breaker is tripped.
2) Using a voltage meter, you can check the regulator on the engine for proper operation with the machine running at full throttle.
3) Testing is done at the six wire plug coming from the regulator.

        3a) With the meter set for DC volts: The black meter lead should be on the black wire.(ground) Test for at least 12.5 to 14.5 volts on the white wire. Being that this wire is coming directly from the ignition switch, there could be a break

               in continuity from the switch to the regulator. Or, there may be a problem with the ignition switch itself. If the voltage is correct in this step, proceed to step 3B.

        3b)With the meter set for DC volts: The black meter lead should be on the black wire. (ground) Test for at least 14.5 volts on the red wire. Anything less than this the system will not charge. Some causes could be as follows. Lack of

             proper voltage on the white wire from the above test. The regulator is bad, or the lack of charging voltage coming from the internal charging coil. To test the charging coil proceed to 3C.

           If 14.5 volts is present but the system still will not charge, the continuity of the wiring from the regulator through the circuit breaker back to the battery must be checked and repaired.

        3c) Testing the charging coil: With the meter set for AC volts insert the leads into the connector, one lead on each green wire with a white strip. This should btween 20 to 30 volts AC. If it is not and at there is at least 12.5 volts on the

              white wire from test 3A then the internal charging coil is bad.

Hope this helps!
