After riding the bike and stopping somewhere, my 95 HD Dyna FXD would not start. No spark. There is a Dyna 2000i ignition module on the bike. Every once in a while, we can get a constant red light to appear on the module, but it disappears. Coil has been checked and was told it was fine. Wiring is fine. Tried 2 new sets of plugs...all fine. Would like some ideas as to figuring out the problem to get the bike started.
