Heres the deal, an advantage of an elec switch is that it can switch n handle more current then points were designed for. Therefore with an elec switch one can pump more current through a high energy coil to get a higher energy spark. Soooooooooo if the new primary circuit (coil + ballast) has less ohms total resistance then say 3 ohms (stock full true 12 volt coil) and draws more then around 4 amps (near what a stock system may draw) there may be more current being switched then the points were designed for sooooooo they burn up faster.
Another cause of premature points burn up is no conednsor or a weak condensor or one mis sized.
You really need to know the resistance of that coil you have and the ballast ???????? If its total (coil + ballast) is around 3 ohms THEN THATS NOT THE PROBLEM BUT IT ITS FAR LESS THATS WHY THE POINGTS BURN UP QUICK or else the condensor is bad or mis wired.
Id try the old regular full true 12 volt coil or else a 6 volt coil plus ballast n see how the points last and insure the condensor is good n wired right also. CHECK RESISTANCE OF THAT PERTRONIX COIL AND BALLAST ALSO with that info I may be able to help more
Perhaps that coil was the cause after all???????? If you had a dead short versus the regular coil and ballast resistance that may over current the elec switch !!!!!!!!!

Today's Featured Article - An AC Model M Crawler - by Anthony West. Neil Atkins is a man in his late thirties, a mild and patient character who talks fondly of his farming heritage. He farms around a hundred and fifty acres of arable land, in a village called Southam, located just outside Leamington Spa in Warwickshire. The soil is a rich dark brown and is well looked after. unlike some areas in the midlands it is also fairly flat, broken only by hedgerows and the occasional valley and brook. A copse of wildbreaking silver birch and oak trees surround the top si
