I'm not sure what's going on here. The ball release all of a sudden went weak about a month ago, but I haven't had time to address until today. The mech was cleaned and rebuilt when I got the machine, and moves perfectly. In test mode, the ball release fires balls out hard, as it should, real hard, but in game, it just sort of leaks out, but most of the time doesn't have enough umph to get out, takes 2-10 tries before it fully pops out. I guess in thinking about it, it always sort of was weak, but at least it got out everytime. I thought the rest of the coils felt weak as well, but I'm not sure about that.
I have replaced previously Br1-4, and C5 and C11. I know br3 is the solenoid bridge. Since this issue I have now reflowed the headers for the solenoids, fuse clips, C8 (solenoid cap), and reseated all power connectors over to the CPU (I know this has not 50v, not sure why I mentioned this). I reseated the cables from the transformer, but I'm now at a loss on where to go.
The other coils on the same daisy chain are the bumpers and slings, and they seem really good. Where do I go from here?
