I have the Supreme model. My battery keeps draining after about a day. I bought a new battery and a new alternator. Same problem would occur so I tightened the belt the tightest I could but the same would happen. Some were telling me that it could be a wiring problem or possibly the starter. If you can please give me some suggestions I would really appreciate it.
Thank you
