I recently purchased an original Mortal Kombat Cabinet. I was told by the seller that it worked "as far as they knew", but the power cable was cut. I spliced on a new end to the power cable, plugged it in, and tried it out. Nothing seemed to happen. When I toggled the machine off, the monitor did indeed turn off. It made the normal shrinking rectangular shape you normally expect when powering off a CRT.
I opened the cabinet up and found some loose wires. There were 3 loose connectors, and a couple ground looking wires just hanging out. Of the connectors, a couple of them obviously went together. The connectors were proper male/female, had the same number of pins, wire colors matched, etc. There is another connector, however, that I'm clueless about what it is supposed to lead to. I attached some pictures of it below. There are 4 total wires that run to it. I have a manual I found online. Two of the wires go into the main PCB on(according to the manual I have) the J4 connector. The manual also claims those wires are control panel related, but those all seem to be wired up and heading elsewhere. I have verified one of the other wires goes to +12v directly on the power supply. The last wire is all black and I assume that it's a negative or ground wiring, but I have no idea. I can't find what that connector is supposed to connect to on the other end. Something coin op related?
Also, I was wondering where would be the best place to attach the ground cable that I have to attach. It is also in a picture below.
I was just reminded as well, I noticed this last night, but I don't have any pictures of it. While I was looking at the coin wiring I noticed a silver wire attached to the bottom of the cabinet in sort of a silver cloth kind of conduit or something. On the end it looks like another ground cable towards the front of the cabinet. It's also hanging loose.
From searching on here there seems to be a few that are pretty MK savvy, so any help is appreciated. I'd also love some hi res shots of other people's wiring in MK cabs if at all possible. That would help me out immensely, but I'll take anything!
Thanks again!
