NOTE I do NOT have a 460 Wiring Diagram so will have to proceed based on a few assumptions and best guesses SO NO WARRANTY or no complaints or GOTCHAS if this isn't correct!!!!!!!!!!Take it or leave it as you wish, it may be right it may be dead wrong, so there lol
1) It sounds like the 12 volt tractor was set up to use a 6 volt coil plus an external series voltage dropping (12 down to 6) Ballast Resistor.
2) It also sounds like it has a ballast by pass (via a terminal on a starter solenoid) which means ONLY while the starter is cranking the ballast is by passed leaving UNBALLASTED battery voltage to the coil which improves starting especially at colder temps.
3) If its wired wrong such that ign switch output current goes through the ballast direct somehow to ground WITHOUT THE ADDITIONAL SERIES COIL RESISTANCE that would cause the ballast to get very hot!!!!!!!
4) If all is wired correct voltage begins at the IGN switch output,,,,,,when on and running but NOT while cranking, current flows from IGN switch to and through the series ballast, then to the coil. HOWEVER while cranking, current flows from switch (or a starter solenoid terminal thats only hot while cranking, i.e. the starting ballast by pass system) direct to coil by passing the ballast for a short term temporary hotter spark.
5) The above can be accomplished if a wire up from a starter solenoid THAT IS HOT ONLYYYYYYYYY WHILE CRANKING is wired to the ballast output or coil input (same thing electrically).
6) If you use the ballast, and its a 12 down to 6 voltage reducing ballast, YOU NEED A 6 VOLT COIL which may be labeled "6 Volts" or "12 Volts FOR USE with Ballast Resistor" or "12 Volts Requires External Ballast"
7) If you do NOT use the ballast, you need a full true 12 Volt Coil. It may be labeled "12 Volts" or "12 Volts NOT for use with ballast" or "12 Volts NO ballast required" etc
8) If you used a 12 volt coil PLUS still used the series ballast the spark will be weak.
My motto, give a man a fish feed him for a day, teach a man to fish feed him for life" So I gave this detailed explanation in hopes you can now figure it all out BUT NO WARRANTY OR GOTCHAS OR COMPLAINTS as I have no diagram only your information and a few educated best pure guesses.

Today's Featured Article - The Great Escape - by Dave Hollrah. It all began Monday with a little baling of second crop on the lake shore field, and as I drove out past my sister and her hubby's place, this small calling sound could be heard from the general direction of their manure pile. Out of the yard, over the cows and bale piles, through the dozer piles, poplars, and brush, out onto the ditch grade road, past the noisy 6.2 diesel engine pulling my well traveled Suburban along. Well it sure didn't take me long to figure out what it was because I alrea
