Donkey Kong Upgrading Problem
markrvp:
I used a standard JAMMA wiring harness. They are available on Ebay from vendors like Tornadoterry and TwistedQuarter. You can also get them from all the arcade suppliers including Bob Roberts.
When you convert a cabinet to JAMMA like I did with the Donkey Kong, the idea is that everything is wired through the harness, including the monitor, controls, power, coin door, and speakers. You can still hook the coin door up as you did (and so did I becaue I was lazy). The coin counter won't work without the original power supply because it needs non-standard power (I think 24v, but don't quote me).
I don't remember where the control panel connects to the DK boards, but you still may be able to hook them up that way. If it were me, I'd get a fully populated JAMMA harness and rewire. However, your machine should at least power up and get video and sound without the controls connnected. I would pull that power connector from the old power supply that's connected to the PCB first and see what that does.

Again thanks for your help.
I disconnected the old PS cable leaving just the coinbox cable but unfortunately. no signal. When I turn on the monitor, it flickers on but nothing more than a glow. I can control the brightness, horizontal and vertical but no game or sound. I will need to check the PS to make sure I am getting the right voltage. Is there an easy way to check if I may have damaged the pcb or have a short somewhere? Or maybe I have a bad adapter? Bad wiring?
Arrggggghhhhh! Soooooooo frustrating.

When I get home tonight I'll open up my DK cabinet and look at a couple of things to see if I can suggest something.

Look at Neilyboy Dk restoration, he unjamma-ed a dk cab, the parts he took off are the ones you need. (Big mess though, i would rewire) He had the original monitor though.

I am going to replace the wiring harness from the JAMMA adapter with a full wiring harness from Mikes Arcade (www.mikesarcade.com). This will also require re-wiring the control panel and the coin box. Is there a relatively easy way to determine if the pcb is okay? It was working before this project started and I hope I have not done something stupid.
Markrvp, any suggestions?
Thanks,
-David
