Having an issue with the Ultimate MPU (Version 9.1 I believe, both boards are a few months old) with Hot Doggin.

Anyone tried these in a hot Doggin?

The issue is related to the switch Matrix, specifically J2-Pin 8 (the "0" row of the switch matrix). Put a new board in a game and that row didn't work, I put on new connectors, checked wiring, and even removed connector and jumped the pins with wire on the board itself and I'm still getting nothing on Pin 8. I swapped in another new alltek board and having the exact same issue. I'm getting nothing in the swtich matrix on pin 8 (White/Green wire). I double checked the wiring on the schematics. I actually have another Hot Doggin in my personal collection with the original MPU. I went and checked it and it works perfectly when I connect the pins either in the game or with the connector off. I also double checked the wiring to make sure It matched what the schematics said and it did.

I sent an email to alltek and it bounced back immediately!

Hey Guys - Figured this out - It looks like the issue was being caused by a short in the COIN door and #3 coin had loose wires most likely banging into something. Side note, Alltek got back to me and was a big help.

I've had coin door shorts before and had it mess up the matrix before but I didn't connect the coin door would effect things on the PF on the matrix, I would have expected only things down there (Slam tilt, Coins, Start Button etc)

So the Alltek boards are fine as is my original!

Back to the slopes - thanks for the input!
