But this was just not happening, so I started testing the path from Player2 10's zero switch to Z2 and it looked OK, this had me stumped for a little while then I realised that because the machine was turned off when I was testing this meant that Z1 was de-energised and obviously the NC switch was closed giving me a false positive. I then pressed Z1 in and of course I lost continuity.
Long story short it ended up being the Player1 10,000's zero position swith was slightly open, I adjusted that an presto, it reset normally.

Only a few things to do now like clean up the legs, install a coin door lock and install the backglass and the machine is complete
