dolly, when you state "I've got power to ignition key and from the key to the coil (+) and from the coil (-) (the coil has a resistor inside)to the distributor...
NOTE With the tractor sitting not running the points are "usually" closed in which case there would be voltage on the coils Input (from ign switch) but there should be zero or near zero volts on its output (to distributor) because closed points takes that to ground
If you ALWAYS have voltage on the coils output (to distributor terminal) as engine is cranked or points are supposed to be closed THE POINTS ARE NOT ACTUALY FULLY CLOSING OR MIS WIRED OR BAD
Check to insure the points are actually opening (to correct gap) and fully closing as dist shaft turns ??????????
Insure the points are correctly wired to the stud inside where on other side the wire runs from the coil
If alls well if you put a test lamp on the coils output to distributor) terminal and turn on ign and crank engine over THE LIGHT SHOULD FLASH ON (when points are open) AND OFF (when points closed) !!!!!!!!!!!!!!!!!
If you now have a full true 12 volt coil there wouldn't be any needed external ballast resistor
If the key is on and points closed engine not running the coil will get fairly hot. When running its not as hot since points are opening and closing
Check if the points are wired correct inside the distributor !!!!!!!!!
Instead of guessing if you work through my Ignition Troubleshooting Procedure it can help find the problem

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
