Thanks for the suggestions.
I had already cleaned the terminals and connectors. They are very heavy gauge wire too.

I had charged the battery and still had the same problem, plus it does not fit into the battery holder in the floor. The guy I bought it from just pulled one out of his garage and hooked it up. so I need to get a new one anyways.

I haven't checked the starter ground but the Frame ground is good.
Until I can get it started again I won't be able to see if it is charging.
