Ok quick update guys

I took the offending score reel out and advanced the wheel to zero and saw the contacts open. I then started the machine and came up with tilt..bleh so i hit the start relay to override the tilt and Ball 1 lit up yeeehhhhhaaaaaa!!!!!

So i hit the right flipper and the motor advances for as long as i press it (i tried short presses and long presses). not sure how i did the next bit but after a few motor turns i was able to pick up the ball with my fingers and fling it up the playfield.. IT WORKED!!!! i feel im getting really close now!!! Chimes arent working but i can see a wire or 2 not plugged in

So whats left (as far as i can see)

1. Work out why tilt light is still on. Someone mentioned that tilt is always on upon start up and a coin gets rid of it. Unfortunately my coin mech is incomplete so need to work another way of starting the game
2. Work out why the right flipper isnt kicking out the ball on start up
3. Scores not incrementing on any reel and doesnt advance to ball 2 when i drain the first ball

This is exciting stuff and im loving it!!!!!
