How to wire an actuator to reverse polarity with relays only, no switchs?
I'm using the L12 S Firgelli actuator in my project.
If I applied 12v and Ground to respective leads the actuator will expand if I reverse the wires the actuator will retract.
I need this:
When I turn my car on the actuator will expand and when I turn my car off the actuator will retract.
How do I wire the relays? Again I don't use a switch.
