Yo Jim, Im not aware of any Thermistor (a resistor that increases in ohms over time as it heats up) use in our old tractors, but believe Ford or someone used it in some automotive applications?????????? It would save a lot of the start by pass and normal ballast problems fer sure.
While on the subject, many here refer to 12 volt coils as being "internally ballasted" sort of like in part of the can theres this stand alone discrete actual RESISTOR. Although a few such did exist, some of which had a lil ring around the can separating the resistor portion, and jdemaris or SoundGuy or someone once even posted pics of old coils with actual internal resistors (some of which were used in circa thirties cars I believe), MANY OF THE TYPICAL GARDEN VARIETY 12 VOLT COILS ACTUALLY HAVE NO INTERNAL BALLAST RESISTORS, but their increased resistance is simply due to more coil wire length or higher resistance wire ANYONE WANNA TAKE ISSUE WITH THAT feel free, its the best info I have available.
Maybe you or Bob M or jd or someone has details or specs or data on the subject?? But far as I know most typical 40's n 50's tractor 12 volt tractor coils DO NOT have an internal pure stand alone discrete resistor hid somewhere inside there

To the newcomer that wants to get out and use the machine for field work, you may have already hit a major roadblock. That is the dreaded "proprietary hitch". With the exception of the
