My 2006 1200 Sportster is dead. As I was riding it the security alarm was going on and off by itself. When I got home and turned it off the alram kept going. After having the alram sound on and off by itself it finally stopped. WHen I turn the key back on the Alram sounded off again. It finally stopped after turning the key on/off several times. I let it sit for a while and now when I turn the key to on no lights or indicators on the speedometer come on and of course it won't turn over. I check the battery connections and ALL fuses, which are all good. I'm not sure what the relay is for on the fuse panel but was wondering if it might be something causing the problem. Any suggested are welcomed.
