they claim with points you need the ballast resistor and with factory electronic ignition you don't..................... They do mention that coil life "may be compromised".
Anytime coil life is compromised, this means "things ain't right." What ya gonna do, on a 1000, 2000, 5000 mile trip carry a coil for every 500 miles or whatever?
What does "compromised" actually mean? 50 miles? 500 miles? 50,0000 miles?
