Voltage Regulator

[Denmack99]

Burned up the voltage regulator when I connected a new battery. The old battery was only one year old. Could something be draining the battery? It is a custom built bike with a 113 Ultima motor. I hooked up the new battery the same way as the old one was done. As soon as I connected the positive the regulator sizzled and a large clould of smoke came out of the front of the bike. The regulator was very hot then. This is something I don't know much about so any help would be greatly appreciated.

welcome....

first thing is- why did you put a new battery? did it go dead all of a sudden, or was it just time?

first thing that comes to mind is a grounded stator. there's a good how-to on this here:

I don't want to steal this thread but my lights dim and brighten every now and then. I haven't done any of the How-to yet but I'm assuming the VR is headed south? Thanks. JR

jr-

real quick- assuming it happens at a higher rpm and not idle (fluctuations at idle usually mean the idle is simply too low- s/b @850 for evos), i'd start with poor ground connections. in most cases, a stator or VR is either good or not....

Thanks Junior. I'd thought of that too, it does happen at higher rpm, sometimes while going down the freeway. It's not so bad when it gets bright but when it dims it can be scary. JR

This sounds like some of the wiring is shorting out or not making good connections. Because the head light changes brightness one could guess that the wires aren't holding connection. Riding down the road could shake some thing loose but since it doesn't stay dim the wind could be rubbing the wire against some metal.
But then you mentioned that volt regulator problem. First off are you sure the wires were conected to the battery just right? Or did some thing short it all out. I got to admit that in order to keep the wires from coming arart on my ride I still use a saudering iron. That way the wind never makes the twisted conection come apart. Sounds like you got some kind of wiring problem. The repair manual makes it easy to trace down.

If he hasn't fixed it since 2007, he needs to set fire to the Son of a Bitch.
