Thank you for the suggestion. I haven't had a chance to try it yet, but I'm planning on giving it a try this afternoon.
It wasn't the battery cables, but that pointed me in the right direction. Behind the battery box was a bird's nest of wires zip-tied together. Within those wires were several in-line fuses. There was a 60 amp in-line fuse that was blown. I replaced the fuse and it fired right up.
