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..
