I have a few problems and I have no clue where to begin. I have schematics & manual but need help understanding what I'm looking at. Here are the problems so far:
1. player 2 ones score reel doesn't reset. The reel scores properly and advances to tens during the game - it just won't reset. I've checked the reel mechanism, and it does move the switches properly when advancing each number. The player 2&5 reset switches seems to work properly as well.
2. backbox light sockets are loose and don't always light up properly. Example, there's a light to indicate when a player has a strike. The light sometimes flashes and then goes out for player one. Occasionally, the light will go back on when the player switches. The backbox lights also flicker off occasionally when scores are tallying. This leads me to believe there are one or more loose connections, but I don't know if that's the right thing to look for. Trying to find one or more loose connections seems a little overwhelming at this point.
3. It looks like some previous owner/tech jumped 2 fuse sockets together and removed one of the fuses. I don't know enough about how these things work to know if this is a problem but it doesn't seem like a good idea. On the other hand, the machine is generally working. . .
Pics are attached. Any help is greatly appreciated. I haven't been able to find much here or on the web about this particular machine.
