Sounds like you're getting closer to the problem.
Might be almost too late now, but do you have access to a circuit breaker to save fuses while testing.
Jaycar sells them for just under $10 but you can get them cheaper online.
Have a selection of these with alligator clips attached.. best thing for sorting out blowing fuse issues 
Thanks guys, I have a few of these but only brought a 20amp one today.
I've gotten a little further with this tonight and it's nearly all working but I think the couple of lights that aren't working weren't working before had this issue.
Unfortunatly I'm still not sure what the problem was though. I removed the globes from the coin door and plugged the door back in then one by one put the globes back in and each time I turned the machine on I expected I'd blow another fuse but it didn't happen. I wondering if it was the coin door connector or somthing else? Anyway I'm not confident that it's fixed for good but for the moment it's working.
