Goof morning Donald, FWIW its my opinion you correctly stated "I've heard others on here mention that sometimes you need a resister in the system?"
If you have a 12 volt car truck or tractor that uses a 6 volt coil THEN INDEED you need a series voltage dropping (12 to 6) ballast resistor between ignition switch and the 6 volt coils input so the coil receives its rated 6 volts NOT 12. Otherwise, the coil can overheat plus the points will burn prematurely. If its a 12 volt car truck or tractor and you don't use a ballast, then you need a full 12 volt rated coil very common and readily available from NAPA and a ton of other suppliers. Similar the coil needs to match polarity with the tractor be it POS Ground (as original on Deere two cylinders) or NEG ground as many were converted especially when alternators were used.
Best wishes God Bless and have a happy Fourth of July

Model numbers were introduced to help farmers and dealers instantly recognize the engine size and horsepower of the tractor, the 4/60 had a four cylinder diesel engine which developed 60 bhp at 2,000 rpm. The 3/42 had a 3 cylinder diesel engine which produced 42 bhp at 2,000 rpm. Th
