One of the machines on my wishlist for the past few years has been Black Hole. Thanks to a budy of mine, I managed to pick one up about a month ago. It is pretty much a complete machine expect for one very important detail... All the Board in the backbox were missing. Other than that, the cabinet is in Ok condition, with the exception of some tape marks on the head, and the playfields could use some love. They are not completely torn up, but there are some bear spots on them,
So over the past month, through various internet sources, I have managed at moderate expense to pick up a board set for the game. This has included a Pascal PI-80 combo board, a swemmer auxillary lighting board, and a swemmer A7 sound power supply board.
I plan on bringing this thing up instages: First check out the power supply with no boards attached. Then add the PI-80 board with no connections to the playfield. Then I need to check out all the coils on the playfield to make sure nothing is shorted before try powering it up.
So to make the power supply easier to work on, I pulled both playfields out of the cabinet.
The first issue I encountered was with the plug. The ground rod was missing. So I decided to install a new plug. Then I plugged it in and started in on the power supply. It appeared to be a mess, complete with wire nuts, but when I broke out the multi-meter, I found most of it actually worked.
And even with everything removed from the backbox, I showed signs of life!
Now, I my next job will be cleaning up the connectors.... Every ground connection is corroded. I have never seen corrosion like this before in a pinball machine. I think the broken ground lug on the main plug may be the reason they all look so bad.
