My check engine & battery light was on. I replaced the battery and the check engine & battery light were still on. I rode bike approx. 70 miles and turned it off. When I went to start it again, it would just click. I let it sit for a while and tried again and it started. I rode for approx. 1 mile and the radio, dash lights and speedometer quit working. I tried to speed up and there was nothing so I pulled off the road. It idled for a while and then quit. Does anyone know what the problem could be? Is it the regulator or alternator or something else?
