hi john; i agree with you on the alt system situation, i leave it to you as whether to pose this to all. there is a cure that a lot of the purists wont like. EVERYTHING i own has the mod on it as i too dislike dim lights at idle. it turns out that the mopar 100 amp alternator, in all instances ive tried, continues to maintain a 14 volt system at what i use as an idle speed. this, of course, depends a bit on the regulator, and ive had ''bad'' regs. the 100 amp alt also has the side benefit of extending batery life as it really kicks the state of charge in the butt and recharges QUICKLY and completely which seems to have a very beneficial effect on the life of the batt, dont ask me y!! another serendipitous effect is that ive yet to have other than a brg. failure on the 100 amp units, they see to b much better built electrically and dont go bad, even wound to 6500 now and then. i very highly recommend the mopar 100 amp alternator, its all but bulletproof, electrically and mechanically!!
