We call that 'The Gate to Nowhere' - it used to be the access to a smallish paddock, but we took the stock fencing down to let the dumpers better access when we dug out the ditches and stream a couple of years ago. The paddock will be reinstated soon, with a double stock fence with hedging between.

Anyway - back on topic: Tonight I've been buzzing out those elusive input output lines. It turns out it's down to two manufacturing errors :bang: all be it slight ones. Firstly two of the termination blocks on my machine were incorrectly labeled, and secondly the 'survey' printed in the circuit diagram showing physical locations also has an error. In the attached picture the upper terminal block, which is 'X206' is labelled 'X103', and the block below it is actually 'X103' but wasn't labelled. :bang:

Makes a lot more sense now.

I think I alluded to this is a previous posting, but we are coming to the end of a major refurbishment here involving rebuilding the farm house, renovating two cottages and some substantial landscaping, and the poor old 'main contractor' has had a bit of a breakdown, meaning I've had to take on his role. Fortunately I've been able to use his sub-contractors (some of which are his sons) but it takes up all my play time :(

However there has been some progress on the machine. Firstly I think I've solved the relay issue. I now have the correct circuit as far as I can tell, and have sourced some identical relays from German eBay:
