Grounding the new metal battery box?
I've installed a metal battery box that is going to hold 2 6volt batteries.
It is sitting at the front, on the A-frame, and is held in place with U-bolts around the frame. Therefore the box is not necassarily grounded to the actual trailer frame.
I have a master on/off kill switch and a 50amp breaker wired inside the box, on the positive side.
My question is, should I include the metal battery box in my ground wire to trailer frame circuit, or simply run the ground wire from the batteries out of the box to the original ground connection on the frame?
