Pulled up to a stop sign last night and the engine started to sputter - like it does when it's running out of gas. I reached down to switch fuel tanks and noticed that everytime the engine misfired all the lights were blinking off in perfect timing with the engine. Engine would rev back to life and lights come on.....engine sputters and lights go off. So there I sit trying to give it gas with the lights and the engine blinking and sputtering on and off. Finally the engine quit dead and all the lights went off ... nothing electrical alive at all. I took the battery cover off to check the battery cables and they both were tight, but I did notice that the positive connection moved just slightly when I pulled on it. After this, I turned the ignition on .. all lights came on, engine started right back up and I rode home. From other posts I've read others have suggested the battery cables might cause this, but the battery was just replaced 2 months ago. The bike is always parked indoors so I'm just skeptical that corrosion could build up that quickly. Does anyone know the torque values for tightening the battery cables? Maybe they vibrated loose a bit but I don't want to over-tighten. Also, if it was the ignition module or some other problem would that cause the lights to blink off in time with the engine? Would appreciate any suggestions of other things I should be checking.
