JAMMA Test Rig Suggestions?

Pages: (1/2) > >>

Witchboard:

I've got a line on a PSone LCD that should be showing up in the mail this week.  I'm wanting to create a self contained JAMMA board tester including a kick harness.  I plan on having about 4' of the JAMMA harness outside of the box so I can test boards in cabinets.  I've already presumed I'll be needing the Test, Service, Coin and both player Start buttons.  Is there any suggestions of something I may have not thought of?  I'm not too concerned about including a coin counter, considering I'm not an op, but I'm finalizing the planning stages and was wanting some feedback on something I may have missed.

An amp meter to see how much current is being used by the 5V supply is useful as is a speaker. Also useful is access to the  5V control and a volt meter to set 5.1V etc for boards that need a bit of boost.



Witchboard:

I have a 3" 8ohm shielded speaker that I'm going to install.  What would be the usefulness of an amp meter?  Not that I'm saying it's not a good idea, I just don't know what pertinent information it would provide.

BobA:

The amp meter will show if the board is drawing too much current compared to its rating.  This is good info when troubleshooting boards.

Witchboard:

Well, I'll be the first to admit that I'm not savvy enough to know what to look at or what could be wrong when it's drawing too many amps.  Not to say that I won't learn in the near future.  ;D  They seem cheap enough on eBay.  I'll take a look at my local places and see if they carry them as well.

I guess one like this would work?  It seems small and affordable.  It states it needs a "Shunt" resistor.
