there could be many reasons the cable is getting hot.
you might try mounting an auxiliary battery in the back, run the 4 gauge to it and run the 8 gauge to the compressors. if that doesn’t work, try running a ground cable between the batteries and the compressor instead of grounding to the chassis.
it was the ground the hole time i had to put a better ground then what i had on there
That’s good news then. Did you fix it by adding a ground cable directly to the battery?
