I am looking to replace my externally regulated alternator with an internally regulated one, if that is even possible. A search of the site yielded a thread on upgrading to a 3G alternator, but I couldn't find anything referencing an upgrade to an internal regulator. That brings me to this question; Is it possible to simply upgrade to an internally regulated alternator on a Ford, or do I need to convert the entire setup to the 3G alternator? How about a one-wire alternator? Anyone running a one-wire setup and if so how difficult was the swap? Long time GM guy with a knowledge base for GM products and upgrades. The Ford stuff is different so I want to be sure I am going the correct route with the alternator upgrade before jumping in. Based on the thread I just read the 3G conversion looks pretty straight forward, but time is a factor for this project.
