Well I decided I had noting to loose this morning so I got a heaver wire a 12ga instead of 16ga, got rid of the toggle switch too hooked to Plus side of coil.
Turned on the switch and hooked the other end right to the battery had s[parks at the battery but that was all and the wire didn't start melting insulation off like before.
Turned the key to start and it started spitted and sputtered for a bit then ran. I left the wire hooked up that way and ran the tractor around a while even skidded some wood to the cut pile.
New ignition switch and I did gain there as the fuel gauge now works.
I had did a continuity check of the wire from the coil to the ignition switch and it tested fine. But I am going to run a totally new wire from the coil back to a connector just in front of the fuel tank and see if that works. If not I will add a section from the connector to the switch so I will then have all new wire.
