If it's not a show queen tractor, and you're NOT a stickler for originality, AND it's running, LEAVE IT ALONE.

The alternator most likely has a built-in regulator, and the coil likely is a true 12-Volt unit that does not need a resistor. If it does, soon the dreaded "burnt points syndrome" will rear it's ugly head.

If you have a good, ACCURATE DVM, you can get an idea of what coil you have by measuring the primary resistance. A true 12-Volt coil will have a primary resistance in the range of 2.5 to 3.5 Ohms.

A coil that needs a ballast resistor for 12-Volt use will have a primary reistance in the 1.6 to 2 Ohm range.
