Malenko:

When I got my Ms.Pac , it was the fuses at the bottom.

The 7amp fuses to be specific

Well Fed Games:

Wow, that is a beautiful machine, even the boards look clean!

Thanks!

Not Fair!   :hissy:

Congrats, pretty sweet pickup.  Now if I could only find someone needing to get rid of one (or a pinball) that would be awesome!


markronz:

Well, replaced the fuses.  Still no dice.  Guess its back to the drawing board.

The three (or sans 3 prong) plug was super common "back in the day". Many houses (or businesses too I guess) from that era do not have three prong sockets. So... since ground is pretty much required on these cabs (or certain appliances), what people had to do was do what you see there or use adapters (see picture below). Of course, for the whole thing to work, the box also had to be properly grounded which wasn't always the case. My suggestion is flat out replace the plug and, possibly, the cable. I would do the cable as well. Those old power wiring tend to crack and crumble exposing the wires inside. I'd rather have a working cab with a non-original power cable than a pile of ashes and embers.

Don't be in too much of a rush to fix it. Patience is a virtue. :)

Have you downloaded the schematics for it yet? You can check the wiring against the schematics and see if they're correct.

Do you have a multi-meter? Those are a big help as they'll help you spot wonky voltages.

Did you actually pull the harness off and visually inspect the edge card or the harness pins? IIRC, doesn't Pac have some bizarre power requirements? Higher than +5v line that tended to burn out the traces? A common hack was to bypass that part of the circuitry. I don't see such a thing but then I'm not in a Pac-Man mindset. Don't quote me, I have my Pac-Man schematics on a different computer and this is just from memory. Someone will correct me if I'm wrong.
