It turned out to be a fried starter solenoid and an issue with the spindle of the starter (was missing a bearing or something and the shaft was loose). Ordered a new starter from a shop that rebuilds them and it fires right up. Turns out the shop owner was a mechanic in the Army and knew a lot about the system. His warning to me was to never wear a ring or watch when working on a 24v system. ”Could fry off a finger” if contact was made! You might be able to replace the solenoid only. Easy fix really, just took time to figure out the issue. Folks on this thread were very helpful!
