Which specific ignition resistor system are you referring to? Deere? Temperature
sensitive ignition resistors were only one of many approaches to controlling point arcing,
ignition drain, etc. The Delco-Remy system, traditionally, used a fixed-value ignition
resistor with a bypass. The Auto-Lite system was one of the first to utilize the
temperature sensitive ignition resistor as you've described.
With some of the Deeres, I'm not sure what was used, but I believe it was a mixture of
both. 1010s and 2010s came new with a temperature sensitive resistor built into the
ignition switch - which had a tendency to burn out. When the updated changeover kits
came out, fixed value resistors with a bypass were used instead.
As far as the compound word "ballast resistor" goes, although I've used it, and heard it
all my life - I'm not quite sure where it started and what it meant at the time it was first
used. Its denotation is that of a "resistor that compensates or stabilizes", but it seems to
have taken on the connotation of any ignition resistor, or laser resistor, power supply
resistor, etc. as long as it's used to compensate for various types of fluctuations.
