A quick summary of a few things that got fixed:
Eight Ball Deluxe had the Game Over lights stuck ON in the backglass. HAD.
I had people over for the Pinball Women Ottawa group I run, and after a night of playing, the next day I noticed that suddenly the Game Over was behaving.
If it was locked on, I was sure a bad transistor, and had one ready to replace it, but welp, it's working!
For all the dickheads out there that whine whine whine about women in pinball: FUCK. YOU.
What we witnessed was the magic powers of women playing pinball: shit just randomly fixes itself, apparently.
Take that, meninists.
Oh, and I had also re-adjusted the upper plastics above the 8-ball target. Now with tighter alignment, shots don't fly by the Bonus Collect hole and in to the rollovers. Very important for collecting bonus on hard shots! It is devastating if you were shooting for that collect and the ball didn't stick in.
Small issue with the ball sitting on the LT5 gate and not falling in to the lock. Expanded the hole on that new LT5 upwards ever so slightly, and now the alignment is far better and the ball rolls down appropriately.
While playing the game would stall on ball reset and say to check coil 7 (thanks, Pascal board!)
But it was intermittent. I'd check it, look for cracked solder, but all was good. On power up, game would reset fine and you could play for a while until the error arose again.
The problem turned out to be the fuse: It wasn't blown, but one side's metal part had cracked / come loose. So when I raised the playfield, it shifted and connected again. After a few solenoid bangs under the playfield, it jiggled a bit loose and caused the error.
1 new fuse solved that issue.
