With the original SDB installed, F3 on the rectifier board blows at power up. I have an Altek mpu board installed. First it would almost boot completely and give me all 7 flashes, but then the red "over voltage" light would come on and not boot.
Now it won't even get to that point, F3 on the rectifier board just blows immediately.
I don't believe the problem to be on the rectifier board because I put a known working one in the game and same thing, F3 blew immediately.
Edit: Installed a new Altek solenoid driver board and now nothing is happening, only the red light on the mpu comes on that says "over voltage".
Any advice is appreciated!
