Singal wire altenator swap?

I am thinking of putting in a 350 tbi engine out of a 89-90 chev.I am thinking of keeping my carb as well as wiring sounds like lots of work.However I would like to keep the serpentine belt idea.If I do i want to keep the power steering pump and altenator.This new altenator has a singal wire and would like to know this hooks up.I have done the conversion already with the internal regulator type i have on it with the 2 wire altenator plug.I have bypassed the voltage regulator by jumping 1-3 and 2-4.and bought an adaptor to go from the origanal 2 wire plug to the new 2 wire flat plug.Anything I need to know and all help appreciated thanks.

Re: Singal wire altenator swap?

Before you switch to a one-wire set up you may want to read up this. The three-wire set up you already have will charge your battery and take care of any electrical loads that you have. One-wire will only charge your battery. Go to this site

I agree one wire blows...but I think what your describing is a two wire cs-130/144 alt if thats the case I would get the cs-alt kit from madelectrical.com the book alone is worth it.

Re: Singal wire altenator swap?

Wow great info never read this one before.Ok so now I will correct myself by saying that I have the 3 wire setup in my 67 now but would like to change to the more modern type in the 88-up style chev.PS I had idiot lights in my truck origanal and swapped out for a gauge cluster and have never had a problem.I noticed that they have a jumper wire from the #2 terminal to the charging wire in there pics why is this?I have no jumper on mine and it has always worked fine in my truck even the gauges.Any thoughts?Thanks guys.
