Extremely stupid grounding question (JPAC).

From the Ultimarc site

Check grounding of the cabinet before proceeding to avoid any danger/damage. The best method of doing this is as follows:

Using an ohmmeter or continuity tester check for a good connection between the following points:

Monitor frame

JAMMA edge connector ground pins. These are the 4 pins at either end of the connector.

Mains power cord ground.

Control panel ground.



Power supply ground if fitted.

I read that, but I read it as saying that those points on the cabinet need to be grounded...

CheffoJeffo:

If you are grounding your controls to the grounds on the JAMMA connector, you are fine.

chairhome:

Thanks, so does that mean I have a different problem with my jpac controls not working?

CheffoJeffo:

Do you get any lights on your JPac ? Can we see a picture of your wiring ?
