Well, not really a curse but I do need to replace the coil on my 1947 Farmall B. This was the first tractor I took from lawn art to running tractor back in 1997, with much help from the sage masters past and present on this forum I might add. I have checked my archives from back in the day and tested the coil as recommended then and I am pretty sure the coil has gone south on me. This tractor is a 12v conversion and I want to make sure I get the right coil. I crossed off 6v but I am seeing 12v with internal resistors (thinking this is wrong) and 12v with external resistor (which I am thinking is right just without the resistor). I have no resistor anywhere in the ignition circuit that I am aware of. The child behind the parts counter just gives me a blank stare when I ask questions so I am putting the question here. Just a straight 12v coil without any resistors?
