Easy fix The battery needs to be good (assuming it is for now).
The fail to start is due to low voltage at the coil when cranking. Small battery cables are usually contributory. The need to be 0gauge cables and solid connections to ground and starter relay.
To prove it is the issue, a second battery can be used to jump start the tractor at the starter side of the relay. With the key on, the jumper battery (even 12v) will bypass the electrical system, and not affect the electrical system at all. I be t it starts right up. If you want to see the issue first hand, put a good meter on the coil terminal connected to the key. When cranking I bet it shows less than 4.8 volts. It needs more like 5.6 to 5.8 volts to start.

I believe the later 350Us were 12 volt . If yours is it could be thew wire that bypasses the dropping resister while cranking engine is broke possibly near the solenoid. This wire supplies 12 volt while starter button in pushed. At least that is the way I understand it.

Where can you get O cables? I can't seem to find them anywhere.

Janicholson · Jun 1, 2010

Truck and fleet repair, and welding stores. (often replaced cables can be had for the scrap price when they are short or have some damaged insulation that can be avoided in their new use. Jim
