Hi all
I have now recieved the car central locking servos.
Big, chunky and waterproof. I fixed a new point to a test board with the servo at 90 deg to it.
After a minor adjustment the servo changed the point every time.
I will be mounting the servo under the base board when I install it outside, but that can now wait for next season.

I have used a two wire central locking servo. Reverse the polarity of the two wires to alter direction. It runs on 12v dc.

I hope this gives food for thought. These servos cost around £3.50 each.

Cheers
