I have an '03 SuperGlide and my voltage regulator went bad. It was sending too much voltage, so it kept eating batteries in about 1-2 months. I live on an island in the Caribbean, so getting parts is an issue for me. Finally got the new voltage regulator, installed it (had to guess at the wiring, as it didn't plug right in) and a new battery and it started right up, ran fine, my gauges started working again, thought it was fixed. Two days later, just a solenoid clicking. Took battery out and there was no acid in it. Thought it was defective, put a new one in and as soon as I connected the cables, the voltage regulator started smoking. Immediately disconnected it, of course. But now what? Shouldn't the power to the voltage regulator not get there unless the key is on?? What am I missing? I'm completely stumped. Any ideas?

 

Do you have a circuit breaker in between the regulator and the battery?
