I’ve got a ‘75 XS650. It was running perfectly the last two years and out of nowhere I realized there seemed to be a draw from the battery when I had the bike parked. Next morning the battery was completely dead. I got it on the lift and starting looking for a short in the easy spots. I disconnected the battery and upon reconnecting I heard a clicking come from the regulator. The clicking stops when I unplug it from the rectifier (everything else still plugged in). Anyone have advice on where to start before I really start digging? Should I replace the regulator? Is this a symptom of another component in the charging system failing? Is this more than likely a short somewhere else? Any direction would be greatly appreciated!
