Hello fellow owners,
I finally got to join the club after years of dreaming about it. I bought a beautiful 2013 Pro. I've spent the last week replacing the Sparky magnet, changing out a couple songs, adding a ColorDMD, and adding a Pinnovators PINPAC. I'm also pretty sure I read every page of this thread. I'm pretty excited!
All was well until I was playing a game and the game started looking for balls after an Electric Chair multiball.
I've since done a switch test and all of Drive 2 does not register in test. (That's all trough switches, all lanes and the pop bumper switches) I tested continuity and I have continuity all the way back to the board. I'm assuming now that it is a board issue but I'm still hoping not.
Can anyone give me some advice on where to look next? If I had to guess I'll have to take off the board and check for any damage. Maybe (hopefully) I'm missing some simple explanation.
What do you all think?

Just a follow-up: It turned out my issue was a faulty wire/connector connection at the trough switch. It ended up taking out the trough opto as well as the sparky and cross optos which are on the same row/column on the switch matrix. Since fixing the connection I've had zero issues.

The lights all show good. I manually checked the cab and playfield fuses for good measure and there doesn't appear to be any fuse issues.
Thanks for the suggestion though. Keep em coming.

I will do that. Thanks!

I'm thinking you're right. I'm going to take a look at the board for anything physical but I may be able to swap it out with a working board just to confirm. Still have my fingers crossed.
Edit: looks like you were correct. The Q2 transistor is bad but already socketed. I should be back up and running soon!

That's my exact same setup, too.

Got an interesting issue the other day:
My Sparky opto and right eject switch don't register at the beginning of a ball. As soon as the lower drop is triggered then everything functions as it should for the rest of the ball.
I'm not getting through switch 4 (r) in switch test but isn't causing an issue that I can tell.
Anyone have any thoughts on this?

Turns out I had a transistor in backwards and was causing my strange behavior. All good again.

Kind of an odd request: I've been a lover of this machine since it came out but I've only owned one for a couple years. 1.80 came out right before I bought mine and I would kind of like to go back and play some of the older firmwares. Do any of you long time owners have older PRO files still kicking around? The older the better.
I want to go back to a time when people liked the machine but it was clear that the code wasn't finished.
Thanks!

Sending you a PM now! Thanks, I'm excited to try them.
