Extremely stupid grounding question (JPAC).
(1/3) > >>

Hi everyone,
I've finally gotten around to hooking my MAME cabinet back up after doing some moving around and trying to clean up the cab's insides... I had a question on grounding.  Do I need to hook a ground wire to the GND terminal on the JPAC or does that provide a ground for me to use on my switches.  I know its a dumb question :-/

Just trying to figure out why I can't get my controls to work right now, running winipac and it doesn't show any controls working.  I know I had a similar problem last year where I had a ground problem with my IPAC, but it was fixed... and now I can't remember what I did.  Thanks for the help, sorry if this is in the wrong section... I haven't posted in over a year!

If I understand the question correctly- all the switches/joysticks etc need to return to the JPAC via a common ground wire. So if its an existing cabinet I would expect a common ground wire to your hardware would terminate at the Jpac

Thats if I understand correctly ;D

Okay, thanks!

I currently have all Grounds on the switches terminating at the Jamma connector.  I'll patch it into the Ground terminal on the JPAC as well.  Thanks.

OK I may be wrong. You are correct in that the ground is carried through the Jamma connection - but it still would not hurt to jump it and see if it fixes the issue. I was thinking Ipac not Jpac

Well, my main question is: Do I need to ground the Ground terminal on the JPAC, or does it supply a ground connection for me to ground the other switches?  I'll try again today.
