Did you drill through the bottom part of the door? Or disconnect any connectors inside the large barn door?
I did drill through the bottom of the door, but not that low. I did check all wiring before drilling but didn't see any wiring going near that locking mechanism, but it's something I will re-check. I thought that because the smaller door will not lock if the larger is not shut properly, only one switch on the smaller door would be needed. Does anyone know if they is a fuse for the central locking and where it might be located? I'm thinking that if it's blown it confirms that I've nicked a wire somewhere and grounded it. If it's not blown, I've dislodged one, or it's coincidence and the central locking is RS.
