    Help! ground issue...i think

    Ok ive had for a few months now my cr pc running of a 400w ac converter.
    THe other day when i started the car the converter burned up and it popped my postive fuse.
    Now i put a new converter in <same model> but if i plug in my pc power cable with the ground on it it wont power up.
    But if i remove the ground from the pwer plug it works.

    system has:
    *postive power block and a negative power block.
    *30amp relay that turns the converter on and off with key
    *400w ac converter
    *1.7ghz mini pc power supply is only 130watt

    The ground distrubion block is still solid because my car amps run off of it fine.
    I also replaced the relay and it still doesnt work.

    have you tried to ground the inverter seperatly from the negative power block? or have you tried to run the inverter off a different power supply such as the positive on the battery or the cigeratte lighter if that model of inverter has that plug.
