Why does it say in the Tech Tips that 4 Gauge battery wires are correct for a stock 6v application? The battery grounding cable was hanging on by a thread at the terminal. I replaced it with a 4 gauge wire from the parts store and haven't had any problems. I checked several websites regarding battery cables for a 1946 application and most major brands say 4 gauge with the exception being Autozones website which stated 2 gauge in which I can't find. They don't even carry 2 gauge inside the stores.
