I am a bit confused regarding the external voltage regulator usage with an internally regulated Nippondenso alternator. I have a Nippondenso alternator off a 95 or so Ram, I want to use it on my 73 A-Body.
Seems like the thought is to use the existing two field wires on the new alternator, but I am unsure if I need to rewire around the external voltage regulator or leave it in place????

Does the Denso alt need the external regulator, does it hurt to leave the external regulator "wired in"?
I have read several posts on swapping in a denso alternator, but am still confused on this point.

Any help is appreciated.
