Once again, thanks to everyone in the thread for helping out. Very much appreciated. Must have seemed like I was going round in circles for a while, but got there in the end. The first day the machine arrived and I actually saw what an EM looked like inside, I wanted to give it straight back. Especially when I changed all the fuses and it didn't make an ounce of difference.

After I got over the initial shock, I said I didn't want to let it beat me and I don't think it has beat me. I'm now able to start a game, play a ball and when the ball drains, it passes the ball back to the shooter lane....now my issues are: the game doesn't end and it jumps to player 4 (on a one player game), but I can see a number of stepper units need cleaning/adjusting.

What's next on the agenda:
* Player unit needs cleaning/adjusting
* Coin unit needs cleaning/adjusting (zero position switch is bent down HARD. Looks like it's missing a peg).
* re-rubber the machine
* new leg levellers

Cheers!
Adam.
