Stator Attack?!? By jomama0867 (Read 644 times)

My 2013 Taotao "EVO" 150 recently lost spark. After investigation, I discovered that the trigger coil on the stator was bad. Alright, not shocking news, these things happen (especially when you log as many miles a year as I do). The thing is, this is the THIRD stator I've replaced in 4 months for the exact same reason (granted none of them were brand new, but they were harvested from scooters with VERY few miles on them, the most was something like 1,200)!

 My question is: could there be something on the scooter "creating" this problem? I have always considered the stator to be a source of power, not receiving any from an outside component, RIGHT? I know this sounds silly, but it almost seems that there is some kind of "feedback" (for lack of a better term) blowing these things!?!

well the exciter coil provides ac to the cdi, the stator also provides  ac to the regulator rectifier, to be changed to Dc to power the lights,charge the battery etc, is it the exitor coil burning out, or the main winding etc? do you have a short somewhere in the wiring, worn spot in the harness etc, how old is the battery? a battery with a dead cell could be overeating the stator,which will  be always be trying to charge it at a heavy current level,  the same thing happens with a bad battery in a car and the alternator
