I just got a Sky Shark cabinet and wanted to get some ideas on what i can do to get it up and running. Here is the current state of the machine. All parts are there, the monitor, speaker, and board seem OK. When I plug it in, the marquee lights up, the monitor comes on, but nothing displays. The board is plugged in and if i adjust what i am guessing is the volume control on the board, some noise comes through the speaker. It is not game noise, just some static. I tried adjusting brightness on the monitor thinking that maybe it was down and that is why i didn't see anything. That did not work. I tried working the coin switched to reset it. That did not work. On closer inspection it seems that this cabinet is JAMMA compatible and was converted from something else to a Sky Shark at one point. There is still a Sega "plaque" on the back that says made in Japan. It looks like there is a new power supply in it and some new wiring. There are 5 wires cut from the harness to the board. Maybe these were not needed after the conversion. Here is the current pinout for the harness and which wires are cut. The cut ones will be noted:

Well that is the way it currently stands. I would appreciate any ideas. I don't want to go ahead and try to reconnect those wires because i don't know if i should or where. I can post pictures later if needed.
