    Main ground goes right to the starter. Then usually a stub off the starter to the frame rail.

    Even a shorted battery shouldn't cause the voltage to go higher than 14v.

    I'm 99per sure you will have to rebuild your instrument cluster or change it I would change it because there will be other things that will go bad like guage and stuff.
