I use to be an elect. rebuilder, and in this case i would first check for a draw more than 1 amp is a draw. you could do this 2 ways the easy way is to disconnect the negetive cable and put a test light is series with the cable and post. is there a bright light or a dim light? If there is a bright light ( this takes 2 people) have someone hold the test light in series like you have it showing the light ON. then pull 1 fuse at the time until you get the light to go out. when the light goes out you have found the draw, just find what that fuse opperates and fix the problem. if the fuse opperates more than 1 item put the fuse back in and check each item 1 at the time until you have found the prob.
if you need any more help please feel free to contack me!!!
