black hole repair

Continued working on the Black Hole tonight.
Found a problem with relay Q - this activated when you start a game and provides power to the flippers and popbumpers (which didn't work on my game).
The relay just doesn't activate.

When I closed it manually, I got a spark/blue flame at one contact point and fuse F4 blew. Oops..
After trying some things I noticed it was a problem with the popbumpers, the coils just locked on.
Disconnected all the popbumper driver boards. Connected them one by one.. results aren't good :(
Four popbumpers lock on immediately.. Two others don't work at all.

I found 2 popbumper driver boards (untested), put these in but the coil locked on immediately. So either I now have 6 broken popbumper driver boards or something else is wrong..

Tomorrow I'll test the boards in my Haunted House.
Once I know these are ok, I'll investigate further what the problem is with relay Q..

Gottlieb Sys80 ground modifications

Started to work on my Black Hole pinball machine. Bought it many many years ago, untested.
Never tested or repaired it. Shopped it, cleaned the playfields, new rubbers, ..
then put everything together (I did test voltages on the powerboard)
Put everything together, started a game, it worked, and then a coil in the back fired and the game just died. Aaargh. Should've known better; but I was young and ancious to get it going.

Put it aside for many years, never worked on it as other games came in and got priority.
Now I'll finally start working on the game and try to get it going.

My Haunted House machine is in good working condition, but never got any upgrades.
As they're next to each other, it's easy for me to do the same upgrade to both machines at the same time.

I've done all the mandatory ground modifications as was described in the past on the pinrepair website. Most of this info is also available on flippers.com and other gottlieb repair sites, in case you need it.

Now all grounds are tied together, should make these System80 games more reliable.
As my Black Hole is the European version (no infinity lights or double backglass), the backbox is smaller and pcbs are at the backside of the light insert panel. So it wasn't an identical installation on both games, some wires needed to be different in size, also have a few less boards than in my HH or USA version BH.

Also noticed the sound board in my BH is incorrect, BH is game number 668 and the board in my game has eprom 667 installed (Volcano).
Not a real problem as I bought a NOS Black Hole sound/speech board many years ago :)
But my game must be working before I try to add that..

I always double checked my work with the dmm to make sure there wasn't an error or short somewhere.. switching the Haunted House on to test it was a bit scary (you never know I made a mistake and blew something) but everything worked.
Great ! Now my Haunted House is more reliable and step 1 on getting my BH working is done..

Haunted House

There's a new pinball machine in our gameroom since saturday: Gottliebs Haunted House !

I'm happy with it.. my wife wanted one, and I won't say no to a new game :-)

We couldn't test it when we bought it, so assembling it home and testing it was exciting.. would it work like the seller said or had we bought a bad machine ?
It was ok.. kind of :)
The cpu has no acid damage (great !) and the machine booted. I could start a game..
There are some issues with it however, one upper playfield flipper is very weak, and both bottom pf flippers don't work (one barely moves, the other it totally dead).
It also needs a good cleaning, new rubbers, ..

It's not the best looking game cosmetically. The backglas is perfect, plastics are good, but there are some heavy wear areas. If anyone has new playfields for sale (esp. upper and lower) then let me know..

I rearranged my gameroom, now Orbitor One, HH and Black Hole are next to eachother. Impressive to see such three huge widebodies together.
