AMEN JM I AGREE 100% You are correct (but you know that anyway this may help others who arent sparkies)
heres a copy of my answer to George below saying basically the same
Good technical question George So what will electronic ignition accomplish on old tractor? Here's the engineering answer: I cant cover in a few sentences what it may take a library, education and experience to fully convey especially to a non sparky but I do try my best
1) Iffffffffffffffffffffffffff its working ???? (NOTE IF) its possible to achieve higher ENERGY discharge (Volts x Amps x Time) across the plug gap when it fires
2) Often improved starting and idling
3) Instead of bouncing ringing burning mechanical contact points a solid state device switches coil current on and off
4) An elec switch yields a fast more positive (On or Off period) coil current switch then bouncing ringing mechanical points.
NOW as a FYI to those non sparkies who dont realize or understand the physics or electronics listen
1) The voltage at which the plug fires is a function of SPARK GAP DISTANCE and the medium (fuel and compression) in which it fires.
2) Just because an elec coil current switch replaces bouncing ringing contact points DOES NOTTTTTTTTT NECESSARILY RAISE THE VOLTAGE REQUIRED TO ARC JUMP CURRENT ACROSS THE PLUG GAP........ Coil voltage ONLY rises high enough to fire the plug no more REGARDLESS if points or an elec switch is used 3) Just because one uses a so called HIGH VOLTAGE coil does NOT increase the voltage at which the plug fires, if all else is the same it fires at the same voltage an old stock coil fires, points or elec switch
IE if all else is the same regardless if an elec switch or points switch coil current on and off THE PLUG FIRES AT THE SAME NOTTTTTTTTTTTTTT HIGHER VOLTAGE
HOWEVER if the plug gap is increased (elec or points) voltage increases
THE PROBLEM IS if plug gap is increased and voltages increase (as often done when using an elec switch and HV coil) OLD CAPS OR ROTORS OR PLUG WIRES CAN BREAK DOWN and people blame it on an elec switch. Its a High Voltage problem NOT if poinst or an elec switch is used for coil current
An old tractor elec conversion IS NO WHERE NEAR THE QUALITY of an auto ignition and they can fail miserably
NOW LISTEN Im NOT pushing or arguing for points or elec switch TAKE YOUR CHOICE. An elec switch is engineering superior to points and why the auto industry switched over HOWEVER again a tractor conversion is not the same quality and can go bad
DISCLAIMER George and others, its impossible to explain all this to a non technical person but shoot me an e mail and I will try more.
Use what you like is my advice you get NO argument from me over YOUR choice Im only trying to explain it to yall PLEASE USE POINTS IF YOU LIKE OR AN ELEC SWITCH IF YOU LIKE Im not arguing with you ONLY answering Georges technical question..

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
