I’m struggling with reboots and blown fuses with my Firepower. For deeper context, I have been working on different parts of it for over a year. The game has all “new” boards, Rottendog MPU, NVRAM.Weebly Power Supply, and even some new sound board. It has the NVRAM solenoid saver and the bridge rectifier fuses board. Generally the game plays amazing, until it doesn’t.
I’ve done extensive switch tests and adjustments. Solenoid tests work perfectly. Frankly I am out of ideas.
What typically happens is that I will replace a blown solenoid fuse, or find an always on switch. I’ll get it back together and it plays for a while then repeats. But then there are times like right now where I can draw the reboot by hitting both flippers at the same time, or hitting them at the same time the second the ball rolls over another switch.
It is almost as if it is on the edge of what it can do, and the extra action pegs the board.
I know this must have to do with some kind of grounding or constant on coil, but I cannot find it. Is there some kind of suggested diagnostic procedure that could lead me to the ultimate issue?
Thanks for any tips!
