Those upgrade kits are inexpensive, yet I still have yet to see anything about the idle amperage. I have heard that some of them are actually worse than the stock alternator. Not to mention I have longevity concerns with souped up alternators in cases not designed with them.

As for the '75 model year chrysler alternator..are you using a squareback or one of these big ugly's (which are great alternators, just large and heavy)


The GM 10/12si and the CS series alternators appeal to me as they clean up how much is on my firewall as well as being extremely easy to come by. They also put out a lot of amperage at idle.
