last year the battery keeps going dead after a long run. This year put new battery in again. I'm sick of charging the battery. I checked the inline fuse ok, but replaced for safe measures. I noticed at idle to rev up the head light gets brighter. I put a meter on battery posts, with nothing running 12.8 volts and when running 11.6 volts and stays there when rev up. Could it be regulator? I tried to trace in line fuse wire back but lose it? what does regulator look like? I see a black square box up by gas tank down low.(hard to get too) Need help sick of charging sled for kids.
