OK, did as you said and jumped the tractor using my 5.7 RAM. Hot to Solenoid, ground to tractor frame.
Glow plug lit up like a Christmas tree. Waited 10 seconds to start. She kicked over like a new born colt! I must have bad wiring somewhere.
Thank you much for your help!!
I will try to be succinct. (Not easy for me)

2Thought battery was going bad because I always had to jump it to get enough juice.
3 Tested battery. All good
4 Tractor quit giving me anything; No turning over, no glow plug, no sound at all.
5 Bypassed system by connecting hot...
