Electronic ignition systems often do not use ballast resistors.

 I believe it is from the dodge van which I snagged all the original parts from... I just read that the GM HEI does not use a ballast resistor, but the mopar ones do... I think. 
YET this power wagon engine  came from a military  M-37, 24 volt system, so the original distributor did not have a balast resistor on it as best as I remember...
