New 6 volt golf cart batteries seem not to be charging

I certainly appreciate all the quick responses. I am certain it is wired correctly as that is a simple pattern to follow. However, I used a four gauge wire for the interconnect and I am seeing today in some comments and research that I should have used a two gauge wire. I have not yet checked the circuit breakers and fuses and I will do that. But I’m thinking maybe the gauge of the interconnect wire might be a factor. Anyone have an opinion on that?
