Welcome to the forums.... the lights wont work on some of the older models unless it's running since the lights are ran by a pulse generator, the reason you have 10 volts is the regulator is trying to charge a dead battery, I would suggest taking the battery off check to be sure it is full in each cell if not top it off with distilled water and put slow trickle charge on it for a few hours, overnight is best then check the voltage. If the voltage is good re-install it and try it. put a multi-meter on the battery while you crank it or try to and see what voltage you have, you may be looking at replacing the battery since it has sat for over a year. good luck and keep us posted
