Thanks,

I suggest starting with battery. P,ut a 1amp charger on batt. for a few hours, then check batt. voltage. should be at 12.8-13.1 volts. If that checks out good, key on, no running bike, unplug and check stop/run switch at its plug-in. Should be the same as batt. This COMPLETES the electrical running circuit. If not, remove stop/run switch, dissasemble and clean those brass contacts as THIS switch completes the running circuit and contacts NEED to be clean and IS a common voltage failing area. This IS a good starting point, and let us know what you find out before continuing.
