Im new here and have a voltbike 750 yukon with the 10 amp hour battery i bought used this past spring. The bike was great til it stopped running two weeks ago. Went for a ride washed it down as usual. Next time go to ride no power black screen. Battery seemed to take a charge, took it to an electrical shop tested just fine. Voltbike thought maybe a bad connection so i bought a new ignition and wires but no difference. today took out controller all lines seem to be good nothing seems burnt. Grey/red wire and brown/red wire from controller not hooked to anything. Single brown wire from other side not hooked to anything. Anyone have any ideas?
