thats wrong a alternator acts like a ac magneto in reverse form it can even act as as a bldc motor with a proper controler the gm 4pin ignition module system works on coliding magnetic fields bouth take place in the primery circuit a ac pulse is turned to dc pulse by the ignition module coming from a pick up coil the second pulse comes from the batery exactly from the potential diference from the alternator when those oposing waves hit ich other with high speed for exampel positive and negative pulses hit ich ither you get a spike down the high tension lead you can ither use ac with ac ore dc puls with ac it still will work those are called ac and dc magneto's so that alternator needs a condenser if not you get static in your baterry who will destroy it after some time doe the reson your alternatir is over charging the baterry with more volteg even tought that us not made you get more power considered the ignition system faster working electrical devices like electric motors etc thats the real reason that condenser is there for! those are low reving alternator build for working mashines like tractors if they are put in a car they will over charge a baterry you get a sport car out of your lazy normal ignition system this is considered as a waste spark ignition system as well by fiering on compresion and exaust at the same time your car will have more power
