I purchased a new actuator and it works when I connect it hot to a 12 volt source and reverse wires to extend and contract the piston. I also replaced the toggle switch on the helm and when I meter the 2 wires at the actuator I get 12 + and 12 - when toggling the switch. When I connect a 12 volt bulb, it lights up. But the damn actuator connected to these wires will not work. Feedback requested please. Happy to provide more information and here is the wiring diagram as the wires at the actuator different colors and not red/blk and yellow/blk.
