Having a power surge problem on my atv...
This can usually be attributed to your regulator/rectifier. It takes the power sent via the stator - and forwards on to the charging sytem...kind of like an alternator regulator in a way. When shot - they can smoke your CDI, burn out lights, all kinds of issues. First thing - there will be a small box with fins on it, usually but not always on atvs with stators - you'll have 3 white or yellow wires coming out of crankcase - they go to your regulator/rectifier - disconnect that plug and make sure none of the wires have been pushed back or it's not caked full of dirt or mud. All looks good (and your sure your battery is in good shape - reply below with year, make & model - and I'll see if I can get you the proper testing specs. Testing them is really easy with any multi-meter; cheapest one they give you at Harbor Freight for spending $10 on Sunday will do. You'll want to pinpoint this and repair asap. A $30 rectifier can kill a $100-$300 CDI fast. All The Best & Good Luck
