So, I recently decided to take the plunge and get into the hobby that I love. Pinball. I picked up a cheap MGOW machine and brought it home to start restoring. When I picked it up it ran fine. Looked like shit, but ran fine. After we put it back together it refuses to start or accept new credits. Each time we tried we'd slowly lose one of the 25 credits it had while it informed us that we had a ball in play. All three balls are sitting in que to launch however nothing happens.
Every now and again it would tell us we had 50 balls in play but still do nothing and not start. I heard there were people on this forum that were familiar with system 80 machines and might have an idea of what is happening. I am including pictures that I took of the circuitry and boards. One picture clearly shows a loose wire and we did fix that. That was causing the screen to error out and show up as only EEEE.
Any advice or help is most appreciated.
