Hi all, Anyone know the correct diode for the pop bumper coil on a Black Hole. Its blowing the fuse instantly upon replacement. I had a 1n4004 and guessing its not heavy enough! Thanks

The proper diode is a 1N4004.
If the fuse is blowing, it's likely that the big can transistor on the PBDB is shorted.
Swap in another PBDB to test.

Make sure you have the diode oriented in the correct direction/wires attached to the right lugs.

From what you wrote sounds like you replaced diode but put in backwards.
Just try reversing diode 180 if your fuse still blows
CH is correct and any 1n4004,4005,4006,4007 ect will work

I had a similar issue with my MGOW. Not exactly blowing fuse on replacement though. Bottom right pop would just stop working (fuse blowing). Top right would pop spiratically and then stop working (fuse blown).

Used this as reference to work on those two boards:
http://www.pinwiki.com/wiki/index.php?title=Gottlieb_System_80#Pop_bumper_problems

- Reflowed solder on the header pins.
- Replaced C4 with 100uf 10V
- Replaced C3 with 4.7uf 10V (with the new polarity orientation as shown)
((Radial caps work for both locations))
- Then I used a trimmed capacitor leg to replace CR1. I only had to do this on one board, because the other already had the jumper.

All is right with the world (Mars that is.)

What is the PBDB and where is it located?

#8 9 years ago

Pop Bumper Driver Board. It is located on the bottom side of the playfield. One board per pop bumper.
