    thats a bad short.even 6 volts is way to high it should be around 35 45 millivolts.

    start pulling fuses and watch the guage,when it drops then you'll have an better idea where the short is.i would start with the cigarette lighter fuse,sometimes those sockets go bad and draw voltage.then the fuel pump relay would be my second choice.
