Can anyone advise how I should wire the relay to operate an electric garage door. Do I just disrupt the power supply to the door or do I have to find the supply wires to the motor
There will normally be a couple of terminals at the controller for a momentary contact switch that’s used to open/close the door from inside the garage. E.g: http://lightwaverfcommunity.org.uk/forums/topic/rollertec-garage-door-controller/#post-23414
If you haven’t got the installer’s instruction manual for your door, see if you can find one on the manufacturer’s website.My Mazda CX-3 Blog: jtonline.info
