I'm about to buy BALLY PAC MAN PINBALL MACHINE

<< < (5/7) > >>

mimic:
Making some kind of progress (I think) I wrongly assumed that just because it passes test that means it works + I didn't understand self test properly (still don't fully) I tested solenoid board and all transistors, everything checked out fine, but when I ground one side of the wire and then touch the tabs on the transistors none of the flipper coils "fire", same with the self test, when it runs through all of the coils, none of the flipper coils "fire" (even though I can operate the right side) and a light at the aux solenoid board starts to flash and I hear loud clicking. Also coil from the coin door also doesn't "fire".
Weirdly I can operate left push button when in pac man maze, but I 'm guessing it just goes to different part of electronics, and has nothing to do with flipper coils.

Any ideas what I can check or do?

Pinball Wizard:
Is this a Baby Pac-man or a Mr. & Mrs. Pacman? Your title says Bally Pac-Man, and before you said it was a Mr. Mrs. Pacman but now your talking about going through a pacman maze.

It is Mr. & Mrs. Pacman, maze is made out of lights on the playfield (I just called it a maze)

Pinball Wizard:
Okay, thought you were referring to the monitor-based Baby Pacman when you said maze.

You are correct to assume that the flipper buttons go through different circuits in the game to control motion of the "maze" lights and the flippers. When you push the flipper button it will trigger a relay on a specific flipper coil board. IIRC the self-test shouldn't make the flippers actually move but instead it triggers the transistor that triggers a coil that triggers the flippers. I maybe crossing my knowledge of Williams with Bally since they were still separate companies at the time of your game.

here is what I'm thinking of doing tell me if this is crazy. I'm thinking of running new wire from the pin that connects on the solenoid board (if I can figure out which pin is that) to fuse that I think is for those coils and then to the coil + a new wire for ground to ground source, just to see if this will work? I'm assuming that each wire that goes from the board goes to each coil or a bank of coils.
