Question for Bubba on ballasts and coils
It's my understanding that ballast resistors have a temperature coefficient. When the resistor heats up the resistance increases, thus reducing the primary current and producing a regulating effect on the coil current. So if I am correct in this, does it also mean that the coils made for use without a ballast are made with primary wire with a similar temperature coefficient?
I have seen coils said to be designed for electronic ignitions, do you know if they are made without temperature sensitive wire? Seems like they would be just plain wire as the electronics is regulating the current.
Sorry to get into the nitty gritty but I get curious about this stuff.
