Coils need to run with about 4 amps of current. Forget about points / no points.

Forget about points / no points. If you run a 1.5 ohm resistance coil on a 12 volt system, without additional resistance, you will eventually burn up the Coils

A true 12 volt coil has around 3.0 ohms of resistance. Should NOT be any additional resistors in the circuit. If there was, the system would have a very weak spark.

This either has additional resistance inline, or you have been very lucky, ..... so far.

Sure, we have a fond attachment to one brand and model or another, sometimes it was remembering that first time we got to climb up in the drivers seat and command that roaring beast, or maybe because when you see that special model, you can't help but see Dad on it, he's gone, but everytime you see a tractor like his, it's a like part of him i
