Take 2 .. I have built this mosfet switch based on 4 mosfets using low side switching of the negative, so far so good, when I un-power the 12v supply it turns of mosfets off, then like wise when I power the 12v back on, so far no great heat coming from the mosets that are pulling about 17 amps divided by 4 mosfets and at 67v, time will tell
