Hi Guys,
I'm new but I was wondering if anybody could help me. I have a 57 Chevy with the stock generator, I've put in a 350 in place of the 283 and would like to know how to wire up an altenator insted of the generator, I have a chrome altenator I want to use, The generator has 3 wires (bat) (feild) (ground) the same as the wires on the altenator could I put a plug on these wires that would plug up to the altenator and still use the generator's voltige regulator?
Thanks! Rodrunner

Rodrunner: Go down seven posts to " Wiring an Alternator" John posted a website with a complete drawing that you can print off on how to wire the alternator. It is very complete and simple to read. When you get done you will be able to hang out your own shingle!! GOOD LUCK Dave E Shank

Welcome Rodrunner and Howdy all

Sounds like you have an early style Delcotron 5.5 1D alternator that uses an external regulator.
Do not try to use your original regulator with this alternator. There is nothing wrong with these alternators everybody today wants a "one wire".

Look at this <a href="http://www.softcom.net/users/acnss/image/DelcotronAltwiring.jpg" target="_blank">diagram</a> and see if your's is like it or not. If yours is like it go to ReWire # 1 Below. If it is not go to ReWire # 2 Below.

ReWire # 1 Delcotron 5.5 1D Alternator

Go to the Auto Parts store and buy a new regulator for '65 Chevy V8. If you can scroung up a good connector (it will be marked F,2,3,4) at a wrecking yard or from a bud for the new regulator it will look a bit better than what I am about to tell you to do. Label the wires so you know where they originally where on the generator and on the regulator. Install the new alternator and the new regulator.

You will need to take the tape off the wire harness between the generator and the voltage regulator and maybe even back towards the fire wall a few inches.

You will find four wires to deal with. One is the heavy red Battery wire that runs from the BAT connection on the voltage regulator to the starter. This wire will be shortened up and connected to the BAT terminal (the large stud on) the alternator.

The wire running from the FLD on the voltage regulator to the F or FLD on the generator can be hooked up the the F spade terminal on the alterntor and the F terminal on the regulator.

The wire that runs from the GEN connector on the voltage regulator to the A or ARM on the generator. This wire can be connected to the #2 terminal on the regulator and to the R spade connector on the alterntor.

Assuming that you have an idiot light and want to keep it working there will be another smaller wire that will also be connected to this one some where either at the voltage regulator or spliced in the harness. This wire from the idiot light can be tested to make sure you have the right one by turning on the key and grounding it. If you have the right wire the idiot light will light. You will connect this wire to the # 4 terminal at the regulator.

Another is the wire that runs from the GEN connector on the voltage regulator to the A or ARM on the generator. This wire will be discarded.

This wire from the idiot light can be tested to make sure you have the right one by turning on the key and grounding it. If you have the right wire the idiot light will light. You will connect this wire to the # 1 or R spade terminal on the alternator.

The wire running from the FLD on the voltage regulator to the F or FLD on the generator can also be discarded.

If your new alternator is NOT a one wire, connect a jumper lead between the # 2 or F spade connector and the BAT post on the alternator.

Remove and discard the voltage regulator for the generator.
