OOOPS my bad, Before anyone or some Troll has a calf or jumps out of the woodwork yelling GOTCHA I was in a hurry (ITs Sunday morning you know) and made a mistake below
For a 12 volt tractor a 1.4 ohms LV primary coil IS TOO LOW and points would burn up prematurely, an elec switch can handle more coil current.

Sorry about that, so many questions so little time but I try my best to help
