You can't have too much ground. A fiberglass car has to use the frame for a conductor. Steel isn't as goond a conductor as copper. To make sure that everything is operating alternater to engine 8-4 gauge engine to battery negative as large a cable as starter positive cable. Things like the dash and wiper motor, ignition boxes,lights and such can all be connected by ground wires running to comon points like a bolt with several wires stacked on a bolt here or there. I have a 70 amp alternater and it hardly ever goes full tilt but I think I could handle it. You want cable large enough to not get hot when being used. The haveiest current draw will be when starting. Useing my car as example electric fuel pumps, ignition, will, allways be on. Fans and lights may or maynot be turned on. I remember reading about the Chevey guys with the high power ignition not having enough ground and the ignition current finds it's way back to battery by way of accelerater cable causing it to weld it's self in place. Another cable for ground from frontelectric componets to battery ground is good insurance for reliablity.
