Jpac in short?

[titalatas]

Hi, all members of this forum. I´m from Spain and newbie in arcade cabinets.

I have a arcade cabinets with a few jamma boards and mvs cartridge.
Recently a friend give me a jpac, but I have a problem. The switch two and three of second player not work, with mvs and jamma plug in the arcade work fine, but pc and jpac nothing.

My jpac is old version like this.


In test mode, pressed ctrl, alt, p show this message:


Any idea?. Maybe someone plug jpac wrong side in arcade cabinet?.

Thanks and sorry for my poor English.

does it show switches pressed when no switches are attached? ((disconnect)

if so the input is broken and needs to be sent away to be fixed.

if the switch is disconnected and now shows no switch pressed...switch is broken or stuck.

Kind of rough reading but I think he said in the first post that an MVS plugged into the Jamma works fine.  So the switches are probably OK.  Maybe the jpac has problems.  Maybe the jpac is not working properly.

Same problem with the wires unplug in the switchs of player.
With jamma boards for example street figther, pang, tmnt ....., not problem works fine.
Test in other arcade machine, same problem.
Jpac to trash, any kind to fix?

Thanks.
