Re: Charging system gremlins 
First make sure you have the correct battery for this engine, no maintenance free or deep cycle. On this engine you will see about 6-8 AC volts per wire at idle. Below are testing for your stator..
Not Charging the Battery
1. With all wires connected and the engine running at approximately 1500 RPM, check the DVA voltage from each yellow wire to
engine ground. The two readings have to be within 2 volts of each other (i.e. if one is reading 20 volts, the other has to read
between 18 and 22 volts). If the readings are not equal, go to step 3. If they are equal, go to step 2.
2. Check the DVA voltage from the yellow wires to the red wire going to the solenoid. The two readings must be within 2 volts of each
other. If the readings are unequal, replace the rectifier. If they are equal on this step and step 1, the rectifier and battery charging
portion of the stator are OK.
3. If the readings are unequal, mark across the connection between the stator and rectifier stud on the low side. Turn the engine off
and swap the stator leads. Crank the engine up and retest. The component that has the marking with the low reading is bad.
