Looking for help with a weird issue that popped up with my Cue Ball Wizard. It is a fairly new to me game, but after a few weeks of playing after a light shop job (replacing bulbs, fixing a couple of light bases that had broken wires, cleaning, etc.) the game started playing the wrong sounds for switch hits. Thinking I had not checked the cabling since I moved it from the previous owner's basement to my workshop/hallway I double checked all the connectors to the boards in the head. After that, I made sure all the chips on the board were seated as well. This appeared to fix the game as the sounds (both music and call-outs) then played at the right switch hits. After another couple of weeks I noticed that the left flipper would fire when the ball was stopping at the gate after the plunge. This eventually devolved into the flipper getting stuck on until another switch was triggered (or at least the second switch hit seemed to turn it off). Now the problem has progressed to a reset while flipping. I can't always replicate the reset but it seems related to multiple flipper coil firings. Has anyone else dealt with something like this? My next step is to inspect the wiring as my guess is that I may have a loose or chafed wire putting power somewhere it shouldn't, possibly in the switch matrix. If it was any one of those things, I would go down a path of isolation for the particular error I was experiencing. However, with the simultaneous problems and strange progression I think there may be something that explains them all, but I need to default to the greater pinside technical skills!

Any system 3 masters seen anything like this?

Ok time for an update. I was busy doing other projects but now had time to dive back in. I ended up finding a desoldered GI wire that when fixed, seemed to have fixed the resets and garbled sound. So progress. I now have some other issues but will start a new thread.
