Long story short - I bought a Big Deal a few months back that had been sitting for who knows how long. It's my first EM. Dug in, got some things fixed on my own, and with the help of a thread :
was able to get it up and running 100%. Took it to MGC where it got through 350 or so games before it had a score reel coil die.
Got it home, replaced the coil, fixed an issue with a playfield switch being stuck on, played a few games, replaced a flipper bat (with the help of a very generous pinsider.) and then played a couple dozen games. All working fine and without issue.
Went to play the other day, and something's gone wrong. When I press the start button, the score motor turns for about a second, and the coin unit stepper steps. But any score reels not on 0 don't reset back to 0.
Since I had the machine on free play, additional presses of the start button add additional players - repeating the above even when the coin unit stepper is on 4 players.
The reset cycle from the manual.
I've tried to follow along these sequences, but my inexperience is tripping me up this time.
Any ideas on where in this sequence things are going wrong? I mean, since the reels aren't resetting, I assume it's something in the first four parts, but I'm sadly lost. If I manually trigger the reset relay, the score reels will reset, so if I'm reading things right, I assume it's actually something in the first three parts.
Anything I can test and report back with to help with diagnosing? I do have a copy of the schematic from PBR - it's on ipdb as well.
