Replaced the stator and stator rotor today. Started up the bike only to have the regulator go up in smoke. Regulator was only 1 year old but a cheap drag specialties one. Wonding what caused this battery was a little low so maybe some of the issue. Dont want to just replace the regulator just to have it burn it up again. Replaced the stator rotor because the magnets had cam loose and were chipped. Any help would be appreciated

 

charge up the battery first, make sure the new regulator is properly grounded.
sometimes they don't like a high current draw

 

Very true. You're motorcycle (just about any bike or car) charging system is designed primarily to maintain your charge and not to charge a weak battery. You might get away with it a couple of times charging it that way, but eventually it will bite you. Always make sure your battery is fully charged. Also a sure way in frying your charging system is by jump starting it. You are better off push starting it when you have a weak battery in case of an emergency and you cant charge your battery first.

 

Should i run a ground wire from the regulator to the ground on the battery. He had the frame powder coated and i think that may be causing some of the issues also

 

I will charge the battery and charge it up to have it tested to make sure it is good. The regulator he had was a drag speciaties one

 

I'm not sure on the wiring for your bike because its an older model. But instead of running extra ground wires throughout the bike, I would just clean off any paint at the ground points and take it from there. Do not rely on the ground to come from just the thread part of the bolts used for ground. They can have some paint on the thread surface as well. Also if he used Lock tight or something similar for the bolts, that would restrict the ground also. Cleaning it up and adding some dielectic grease should be fine. You should also check your grounds with an Ohm meter and check for good wire continuity also. Move the wires around a little while checking continuity, you could have a bad wire some where.

 

New regulator and battery installed today. Grounded regulater right to the battery everthing is working now.
