While ridding in traffic, slow stop and go, my bike just shut off and restarted twice. Kinda spooky, just glad going down hill. We rode on and this never happened again. When this happened all the gages were bouncing back and forth, tach and speedo also. It lost all power but then restarted, like I said two times, then no more. My bike has a new battery, May 09, but it only charges around 13 volts when ridding, around 2500-3000 rpms. My old bike would charge at about 14. New bike is 01 ultra old bike 97 ultra. I just got this bike and have not rode it much yet. Is 13 enough charge. I have removed and cleaned the battery, but have not rode test yet, raining. Buddy said it could be bad battery??? I removed the switch and switch panel to lower the bars, could I have loosened a conection? I didn't loosen any wires, just moved the panel enough to access the bar clamp. Thanks ahead for any replies.
