I just got a few boards in today from a friend to fix, and the first one I take out of the box is a Bally solenoid driver board. Clearly the HV section is smoked, no problem, I've fixed these before. The F1 fuse may need a little attention, too. :)

Oh, it gets better.

The short fuse on the board is a 14A. Manual calls for a 1/4A FB for HV in the Bally solenoid driver board. Yep.

Wonder why the HV is smoked? I wish the fuse was a little shorter, now...

@andrewb , you can hold off on your fuse stretcher for now... :)

I Mean it's slightly better than finding someone wrapped a blown fuse with house wire. Like I have... luckily it was for a flipper gate close mechanism so it never was active for more than a moment but still.

Or tin foil.
Or used a large nail.
Or a chewing gum foil wrapper.

All stuff I have seen.
 
I need to find somewhere I can get one of these.
Hot Glue Gun
Label Maker or printer
Hobby Lobby Frame
Harbor Freight for the wrench
Ace Hardware for almost all the rest
Good luck finding the pull tab at this point.
 
This reminds me of the time when I just started working on electronics back in the 80's. I had a Marantz 2270 receiver that was hit by a power surge. I took it to a TV/radio repair shop. They got it running again. When I picked it up the guy wanted to know if I wanted to leave it for some more testing, he called it a "heat test" for an extra $40. Back than $40 was a lot of money especially for someone who was going to school at the time. So I said no and took it home to perform my own heat test but letting run.

Anyway the receiver ran fine for about 5-6 months and it blow again. By this time I had my basic electronics courses behind me and was sure I can fix it myself. I took it apart and found that those idiots at the shop wrapped a 22awg wire around one of the fuse holders. I went back to the repair shop that worked on it and found that they went out of business, so surprise. It did make it easier finding the parts that were causing the problem in the first place, plus a few others. Maybe the same guy who installed the 14A fuse on your PS was the same guy who worked on my receiver all those years ago and was just simply performing his "heat test".

Anyway, I managed to get it fixed and it's been running fine ever since, still own the 2270 to this day.
