I am swapping out my hydralic engine hatch actuator with a heavy duty Hardin electric actuator. I have never been very electronically minded, so I am just curious how to wire the new hatch into my dash rocker switch? My new actuator requires 12 gauge wire, so my plan was to just run all new wires and go straight off the battery with a circut breaker or inline fuse.(not sure yet)
My main question is how do I wire the rocker switch on my dash?

This is the actuator I am using. http://www.cpperformance.com/p-30-18...-actuator.aspx

Let me see if this helps, you basically make an X across the outside terminals of a DPDT momentary swicth. Then connect the motor to one end and the power feed to the middle terminals.

This is probably a stupid question, but what does VS and OV sand for? And when I make an X, does that mean the same wire goes to both terminals?

VS voltage supply
OV zero volts/ground

Dunno. Let me know what happens.

You can also use 2 relays to control the actuator [1 for up and 1 for down] and then run a lighter gauge wire to the switch itself, the power then runs through the relays and not the switch. I found this made a huge difference on my actuator, it draws less power and it seems to go up and down quicker

Basically that is just + and - voltage, the side doesn't matter. The "X" would be small insulated pieces of wire so the voltage reverses when the switch is paddled back and forth.

As n20 Michael said, you can also use relays near the actuator but the circuit for this is more complicated. You need to use 10 gauge or better wire to get good voltage to the actuator from the helm if you don't use relays.

Like said before, put in some relays.

I'm like MCKILLOP, what if you are wiring 2 elec actuator how would you wire and will the actuators be sync

I used this same diagram and it worked great! Hatch moves fairly quick.

The relays allow full voltage to reach the actuator instead of traveling to/from the switch
The wiring of two actuators is easy.
Just don't place limit switches in the actuator. The actuator will run till the switch is released.
If one actuator reaches limit of travel sooner- let it ratchet till the other actuator limits out- then run both actuators back the other way for 5 seconds to release the actuators off the mechanical stops.
