Hey guys I’m glad I found this thread as I just picked one up today. I’ve never worked on an em so this will be an adventure lol. Mine powers on but pops a fuse when I hit start button. Also the score motor on bottom cabinet just keeps spinning. I’m looking for a manual to buy as I believe fuses are not proper. Also my wiring looks different off my transformer..

Also I’m new at posting on here as it seems confusing. Apologize in advance

So I’ve started cleaning everything which will be a long process… printed out the manual. I’ve noticed several loose screws on relay’s and starting to trace wires. I’ve found a bare burnt up wire on came setup. I suppose this one has many issues. At this point I just want the start motor to stop. Not sure yet as to why it’s blowing fuses on the 15amp fuse (3rd one down) but I believe start motor should stop without pushing start button.

Maybe ball count or advance not going into reset? I’ll be pulling and cleaning those boards and spider. Hard to tell where test position is on schematic.

Is 400 grit sand paper ok to use between contacts? I see so many different opinions on this. Also what’s best to use cleaning the grease and traces on ball count board and other in back box?

I suppose it could be any one of those relays. I need to look up sequence of operation as I’m unsure if the score motor comes on when powered up. I would think it comes on initially when start/replay button is pushed. I’m going to start with cleaning those first and check them out

I found this on Pinwiki which is helpful.I’m leaning towards the steppers being dirty not getting to resting position. So much to be cleaned on this game.

Anyone know if the goal advance should be in between contacts? Also I’ve got som progress cleaning up burnt wires and switches

I ended up figuring it out from hours of research lol. Only used on a few of them then went out and got the Dremel 443 which was so much better and faster. I still need to pull the playfield and clean all those up. Almost at the point of powering it back up and see what else I’ll need to do. Waiting on a resetting circuit breaker to come in so I don’t go through fuses.
