OK so I bought this bike not too long ago (06 street glide flhxi) and a couple weeks ago I parked the bike went in for the night, went to take the bike to work and the battery was dead. Did some test found it was the voltage regulator Removed and replaced it all was good. also replaced the battery in the process since the battery was the stock battery from 06. Didn't ride for a few weeks, went out to the garage to take her for a spin and again. Dead. So I went out and bought a battery tender today, i put a slight charge on the battery and took the positive battery terminal off and it read. .05 volts. So I have a slow drain somewhere but how do I know where? What do I do from here. I just put a daymaker headlight on the bike recently. Is it possible this could be the issue? Any help would be great.
