Thanks to Tim, Tiny, and Jerry for your good responses. I've now learned that "bigger is better" when it comes to wiring cables, so when it's time to replace I'll go bigger than 4 ga.
I'm trying to keep the 6V system intact rather than converting to 12 but sometimes I wonder why. Switching would really solve a lot of problems.

Thanks again fellas!!
