There's lots of info out there on the black and white monitors. They're straightforward to fix, and schematics are available at the usual places online. Just look up the model number of the monitor.
This ended up not being the monitor.. 1 Machine has a non-working boardset, and the other has a power supply problem. I need to install one of Bobs edge connector repair kits, as there have been some terrible repairs on the pins already, and the solder is gooped up so high the cable will hardly slide on.
I replaced all of my edge connector housings and that solved some problems I had. The original housings are terrible. Don't forget the housing for the explosion lights. Check out the Sea Wolf test rom I made. Might help you out as you get your SW working. http://forums.arcade-museum.com/showthread.php?t=151955&highlight=sea+wolf+test+rom
