My 2008 Street Bob died on me last night. I got a mile down the road, it backfired about 3 times as I hit the throttle and then went completely dead. No lights, nothing. Checked main fuse, ok. Turned on and off ignition and still nothing. Long push back home. Mechanically challenged...where do I begin to look for problem? It's obviously still under warranty if I can't make a simple fix myself. Help is appreciated.
