Hello all. I have scoured the internet for what might be the issue with my machine. It's been in our house for about 30 years now and has always played fine until the past few years. When it first started having hiccups the startup sequence wouldn't finish and would just keep repeating over and over. I've gotten that resolved by looking at relay's (specifically Ax) and adjusting. Seems to be starting just fine now, kicks out a ball and nothing (Exactly, like what's going on with the thread I'm linking below). Startup routine now runs fine, ball kicks out, playfield is lit but no targets work. no points can be made. If ball is ran through it just kicks it out again and Ball number is not incremented. Tilt is not turned on and all other relays I've looked at look to be adjusted well. I'm technical, but not electrical engineer technical. Hoping someone can point me to a direction here. I've ordered the schematic (figured i've owned this machine for 30 years I should have it), but in all honesty reading schematics is not my thing (but I'm hopeful I can learn more in this area).
Here's what I've looked at:
Ax, Bx, Cx relay's confirmed and/or adjusted.
looked at other relays in researching issue. Tilt hold, etc. Every other one I've looked at looks to be functioning properly with right make, break, or make/break.
A few of these look like they are brown (from heat) on the plastic piece that sits by the relay coil (what I would call it). Is this normal? They look to be working when starting though (at least what I "perceive" to be working}
reseated and used wire brush on all the "jones plugs" I could find (even the ones in the back of the cabinet).
checked all fuses, reseated and cleaned if needed
I'm out of ideas and hoping someone has come across this? Thanks in advance for those reading.
