Well found a burnt up wire and fuse at F3 (20 amp). What exactly does that F3 do? Powers the board or monitor? I get no sound and no picture.

Well I give up tonight. Got the marquee and coin box lights on and some hum to the monitor. Might be a bad board. The red light on the board is on but nothing happening. Multimeter checks tomorrow.
Help! I replaced the burnt wire, 20a 32v fuse and this board on the back started smoking! What is going on? **update** needed cleaned. Noticed after I took picture. Power is on and still nothing. No picture, no sound. Marquee and coin slot lights work.
I humbly offer my PPII Power and Cooling video for your consideration:

DC volts (V with the straight lines next to it) in the 20V range. The CPU and video boards have test points on them near the connector, which is where I attached the jumpers in my video. They are quick connect lugs, and they are lableled +5 and GND if I remember right. Red lead on +5, black on GND. If you are lucky and everything is working right, the voltage can be adjusted with the little adjustment screw on the ARIIs, one board does the CPU and one board does the video.I'm new to this, what setting on the multimeter and where do I place the testers on the board? I have cleaned the interconnect.
