Re: Dual tanks not switching

Actually disconnect the valve first and try to start the truck and see what you get. Then You can disconnect all the wires to the valve, connect 12 volts and ground to the green and light green wires then reverse polarity and it should switch. if it does not, then you have something wrong with the valve.... I would have Bench tested it before i put it on.. You should have at least heard or felt something.
