First thought it was a kill switch problem. Replaced switch and charged battery. Started right up and road several times. A couple days later motor cranked over and would not start. Checked for spark at plug nothing. pulled all electrical connecters apart, cleaned and applies die electric grease to all. Put the battery charger on and it started right up. Again several days later problem reoccured. I was told it could be the stator. I pulled the cover and looked stator over for broke wires or bad connections found none. reassmbled. Started right up again.I need the specs to test the stator. any suggestions would be apprciated.
