My FIRST recommendation is LISTEN TO WHAT PERTRONIX SAYS TO USE versus myself or others in order to not void the warranty (IF applicable). HOWEVER that being said, as an engineer its my opinion the elec switch does the same as points did IE it switches coil current ON and OFF AND SO LONG AS IT CAN HANDLE THE CURRENT BEING SWITCHED (which it surely does) OTHER SUITABLE COILS (iffffffff correct resistance) SHOULD STILL WORK FINE.
One disadvantage of points is if current is exceeded they can burn prematurely while if an elec switch is used AND IT HAS ADEQUATE CURRENT RATING THE COIL DRAWS theres little to no degradation as compared to mechanical point contacts.
Another opinion is unlike high compression racing engines where high energy ignition is required, an old low compression low RPM tractor engine benefits far less (if any at all) from a high energy ignitor coil versus an old stock coil.
BOTTOM LINE 1 follow Pertronix (IFFFFff necesary to void any warranty ?? ask them not me) but if you use a stock coil PROVIDED ITS RESISTACNE DOESNT CAUSE MORE CURRENT THAN THE SWITCH IS RATED FOR I doubt in an old low compression tractor engine theres much difference THATS JUST ME AND MY GUESS
Not having the specs Id GUESS the current rating of the switch IS PLENTY ADEQUATE for a proper coil stock or pertronix
BOTTOM LINE 2 DO NOT ue a coil that causes more current draw than the switch is rated for
OPINION the high energy coil recommended by Pertronix may not cause much if any noticeable improvement in an old tractor while a proper resistance stock coil will still work as the switches current rating isnt isn't exceeded. IE I dont think a high energy coil is required at all but when choosing a coil make sure it doesn't draw more current then allowed by the switch.
OPINION I would use a 12 volt coil (Pertronix or stock) NOTTTTTTTT a 6 volt coil plus an external series voltage dropping (12 to 6) ballast resistor.

Today's Featured Article - A Lifetime of Farm Machinery - by Joe Michaels. I am a mechanical engineer by profession, specializing in powerplant work. I worked as a machinist and engine erector, with time spent overseas. I have always had a love for machinery, and an appreciation for farming and farm machinery. I was born and raised in Brooklyn, New York. Not a place one would associate with farms or farm machinery. I credit my parents for instilling a lot of good values, a respect for learning, a knowledge of various skills and a little knowledge of farming in me, amo
