Hi guys, I have a Bayou 220 that I just aquired, the previous owner commented that I need to leave the headlights on all the time while running the quad, or the engine will act funny. Well I thought nothing of it, and now I have witnessed this issue. With the engine running in neutral,lights off, occassionally the problem of the engine wont rev,just like a rev limiter. When I turn on the head lights, the rev problem goes away. OR if I disconnect the altenator 3 wire plug, the rev problem goes away instantly, but I know I can't keep that plug unplugged. Any ideas out there? Thanks ahead.

 

Sounds like a voltage regulator problem.

 

Yea, sorry about not posting back with an answer. I checked the voltage regulator' and it is going bad. Thanks hillbilly racer for replying back.
