Good news. Many are having trouble with the system going totally dead. I solved mine. There is a black wire that goes directly to ground from the battery BUT the one that feeds the systems is a spur connected to it. It is black and white. I suspect I pulled it apart removing/replacing the rear carb. I accessed one of the B/W connections at the tail light in the rubber thing behind the big rubber box under the seat.I jumpered from the tail light feed to engine ground and IT IS ALIVE, ALIVE ! ow waiting for the battery to charge. Then I can see if cleaning the rear idle jet solved my original problem. If I canĀ“t access the ground socket without disassembling the scoot, will run an auxilleary to ground from a B/W wire
