I acquired a Black Hole in March 2013, after sourcing parts and sitting on it for while on Friday last week, I finally was able to move it from the garage to my home office.
First I would to start with f@$k these machines are heavy!
Repinn ef a missing connector was cut off.
Then I replaced the power supply board, MPU and driver boards with a Pascal board. I didn't want to mess around with original boards as pcb repair is not my strong point. Also my experience with pascal board has be great. I have several in my system 1s.
I removed the lower playfield for ease of access while I work on it.
Replace one coil so far. Large drop target bank cool with fried.
Replace 4 displays with spares I had. No look nice and bright . I would like to thank
Blair for his advice about rejuvenating these display.
Tightened the screw on both bottom transformers as they were loose and buzzing.
Replace a lots of fuses quite a few were blown, a few over sized fuses replaced with correct ones. I did put some 3amp fuses were there was 2.5amp. I have thought about putting 2amp ones..not sure these drive the Pop bumpers individually .
Metered all the coils to check for shorts or open circuits.
Replace 2 pop bumper boards as one missing the other suspicious (blow fuse associated) .
Replace a lot of lamps.
Games is booting up ok, with most lamps on the upper Playford working except 1. I will check the plugs soon
I have new plastics , rubbers, flipper bats, new drop targets, new lower playfield window, yet to install.
Just a few pics, nothing really interesting yet.
