Hey all, I'm having a hard time tracking down what's killing my firepower board. I've got the mpu/driver combo and I follow the installation instructions and get as far as being able to start a game. As soon as I trigger the right sling IC7 fries on the board.
I've gone through the game and I have tested every diode under the playfield and replaced any that were even slightly suspicious. I have every solenoid unhooked right now (red wire off and certain non of them are touching anything). The game was previously working, but it has been broken for a few years and am now trying to get things going again. Prior to the new board being installed I had found one of the orange wires on the right sling had fallen off and was likely shorting to ground, which I had fixed. Would it be possible that the small capacitor on the switch would be bad and that's causing the issue?

Thanks in advance for any help you can give me.

I can't remember if that was one of the diodes that I replaced or not (I did test every diode and replaced any the were even slightly suspicious), but all of the coils have their red wire disconnected, so don't think that could be the issue...

Edit: so far as I know, ic7 is for the "special solenoids" ie the slings and pops.

Here's the right sling. I had a close look and it's wired up exactly the same as the left sling.

Definitely not. I made absolutely sure that none of the solenoid wire were touching anything.

I'm out of town for a few days, I'll check out that voltage when I get home & report back. I wish there was a tech available, my only local option doesn't want to work on sys 6
