A mounting bolt came out and destroyed the larger coil in a tao 110 cc. . I replaced bolt and it stil ran . I then bought a new stator but when I tried to hook it up, pluging in the white to white wire would blow the fuse.
When running it with the old stator it would run with all the wires plug in. Also with the new stator installed it will pop headlight bulbs when rpm (voltage) are high. White wires not connected, But still able to run.
Questions, What does the larger coil do, where does the white wire go, and could it have blown the (voltage regulator?) when that coil was destroyed?
thanks for any help in advance, jeff

 

sounds like you need a new voltage regulator or another stator

 

I agree with NewportHillClimber about needing a new voltage regulator.

That coil that was damaged in your picture is the battery charge winding. It generates an AC voltage that varies with engine speed. The purpose of the voltage regulator is to rectify the AC output into a DC voltage, then regulate it to 14 volts or so to keep the battery charged up. The rectifier part of the voltage regulator is supposed to keep current from the battery from going backwards through the stator (and blowing a fuse), and the regulator part is supposed to keep the voltage from getting high enough to burn out lights. Sound like neither function (rectifier or regulator) is working.

 

Thanks. the new stator is in and I have a spare voltage reg. that I am putting in tonite. One more question. Would the regulator being bad also effect the battery charging. Thanks.

Yes

If its not working the charging system will not function properly.
