Lee, the voltage at the coils input should obviously be whatever the coils rated voltage is, like 6 volts on a 6 volt coil and 12 on a 12 WELL DUH.
NOTE a full true 12 volt coil may be labeled "12 volts" or "12 volts NOT for use with external ballast resistor" HOWEVER a coil labeled "12 volts requires external ballast resistor" is in reality a 6 volt coil and requires the ballast (if on a 12 volt tractor) just like it says it does.
Sooooo on a 12 volt tractor you can EITHER use a full true 12 volt coil ORRRRRRRR a 6 volt coil PLUS a series voltage dropping (12 to 6) ballast resistor.
Again, on a 12 volt tractor, if its a true 12 volt coil DO NOT use any ballast, but if its a 6 volt coil, use one.
NOTE if you say you just switched a tractor from 6 to 12 volts and are still gonna use the old 6 volt coil, THE PEOPLE WHO TOLD YOU TO USE A RESISTOR ARE INDEED CORRECT. Unless you also switch to a 12 volt coil that is.

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.
