    I have a galvanized steel trailer, with a metal battery box up front. Has anyone been shocked from insufficient ground?  Aluminum has 4 times the conductivity of steel.  My plan is to run a heavy copper wire from the grounding block back to battery ground. There is a grounding bolt near battery box for the battery, and another ground in back near my grounding block where all ground wires from the 12v fuse block run.



    Is is just 12 volts there? If so, no worries. You can’t get shocked at that voltage. As to the concern about steel vs aluminum, remember cars just ground the negative post of battery to steel frame generally, and don’t run negative wires to each load.
