Dammit. Turned on my Wrestlemania today and I got nothing. Marquee lit up and the monitor powered up, so I turned the cab off and back on again. Nothing. Ok, "power supply must have died," I thought. I proceeded to install a new one, verified voltage levels, and hooked the Jamma wires to it. Turned the cab on again. Bingo! Board booted up and began the rom check. That's where the story takes a turn.
After the board finished it's checks (all roms/rams/components pass/green), it immediately resets and just keeps repeating the process. Luckily, I had a spare Wolf Unit board and swapped the roms into it. Slaved it in the cab and presto! No more resetting and game plays fine now. I now have no more spare Wolf Units and I'm stuck with a board that keeps resetting.
Damn power supply must have sent some errant voltages and took out an unknown component on the board. I haven't really troubleshot anything. It's on the bench in the garage. I'll get to it later. The story ends somewhat happily, but now I have ANOTHER Wolf Unit board to troubleshoot. One more example of a power supply taking out a board.
Just felt like sharing. Thanks for reading!
