    JAMMA ground wire melting



    not sure if I am somehow getting voltage coming back the ground...but my one ground wire is melting and has exposed some areas in the line. Any ideas why this would happen?

    Would trace it back to where it comes from and check it out.

    Coming straight off the power supply?

    Check all the connections in that ground bundle. If some have failed the remaining wires will overdraw amperage and cook.

    Most likely a short if it's pulling enough current to melt the insulation. Trace it back immediately.

    So I traced it around and it was the ground going to my jrok? Snipped the wire out and connected the jrok ground to the audio ground. Plays fine but will keep an eye on it.

    Hm. Maybe something about the connection to the TV?
    I turned off signatures. So should you.

    For MVS it's ok as the system doesn't have the -5v line connected. With other systems it can be a fry fest. I'd remove the insulation and make sure it's not tied to the -5v line.
