Bob, I checked the big plug that plugs into the control unit and I dont see Y anywere but any way I checked every prong and I cant get no voltage with the wheel spin as you instructed. There are a couple of them that do indicate 12 volts constant. I dont know what else to say, Im confused please let me know what else to try or check, maybe something stupid were not thinking of? I bought the car for a great price and it was kinda not taken care of, although it is in good shape, so I dont know how long its been like this, Please let me know what you think, Thanks Rick
