Some JAMMA questions, need help
<< < (2/6) > >>
BobA:
I would replace the jamma connector/harness if the existing one is burned.   A new harness is relatively cheap.

Lucky & Wild is listed as a JAMMA cab on KLOV so not sure what adapter card you are looking for.

RayB:

First step is measuring voltages coming from the power supply. Those need to be within range and stable.

I don't know what you mean by adapter card. That thing the main board is plugged into? That's not a standard JAMMA thing, so you're not likely to find another one easily. What's wrong with it that you suspect it's bad? Is the burn on that thing? I'd unplug it, clean the board connector traces with a pink eraser, plug it back in. Clean up any burnt connectors (jumper them if they are burnt up beyond use anymore).

Inspect the metal contacts. Might be best to replace, but if the burning is only in the plastic, then you're fine.

Usually only that one.

The green on the monitor concerns me, but we won't know for sure uintil you get a proper signal going to it.

Thanks for your help Ray, see below:

That I have done, and they all check out.

From what I am told the thing the main board is plugged into is some kind of Namco adapter.  I can't find anything that looks like it on the Web though.  And yes, that's where the burn was.  There's a white connector on it that you can see in the pics I posted.  It's a little square 9-pin mobob.

This is a recent rebuild of the monitor chassis including a new flyback so, nothing has been "dialed in" yet as far as the appearance goes.  Hopefully that will improve once I get an image from the PCB on there.
RayB:
Yeah replace the whole connector.

That's where I have a challenge currently.  I've checked the jammaboards site and did not see a connector like it.  I was thinking about using a 9-pin molex connector from an Atari linear PS board, but I'm not sure if the dimensions are the same or not.  I have to check it out this week.

Are you by chance familiar with any place that would carry that connector in its current form?
