1965 Mustang Generator To Alternator

Question: - 1965 Mustang generator to alternator

How do I convert the generator system to an alternator on a 1965 Mustang 6 cylinder automatic ?

Please I need help !

Answer:

Sorry for the long delay! I was wanting to do an actual full blown feature on how to convert from a generator system to an alternator on the early 1964 1/2 and 1965 Mustang, so I was holding off on the answer so that I could provide a better, more complete answer. But unfortunately due to unforeseen circumstances, that hasn't happened yet.

So, for now, I'm going to give you a brief rundown on what you need to do and what parts you need to get to make a 1965 Mustang generator to alternator swap.

First, the good news. For the most part, your wiring will stay the same, save for some new connectors and some switching around of components.

Parts needed:

* alternator style voltage regulator
* 12 volt 1965 Ford Mustang alternator
* upper and lower Mustang alternator brackets
* new alternator belt (different lengths)
* wire crimper, splice connectors etc.



You have a number of different color and sizes of wires from your existing generator harness. Here's how to make the changes to make the 1965 Mustang generator to alternator wiring swap.


1. Black/yellow 10 gauge wire

This wire, previously attached to the 'A' or armature terminal is now connected to the battery side of the solenoid.



2. 'B' Terminal Wire

Then connect a new Red 10 gauge wire from the 'B' terminal of the alternator to that same battery terminal on the battery + side of the solenoid.

3. Smaller yellow wire

The smaller solid yellow wire goes from harness to the 'A' terminal, then goes from 'A' to the horns.

4. 10 gauge yellow/black wire

The 10 gauge yellow/black is connected to the ground/bolt hole on the alternator regulator and is looped over and attached to the 'G' or ground terminal on the new Ford Mustang alternator

5. Black/Red

From the 'S' terminal on the alternator regulator, the black/red wire goes to the 'S' terminal on the 1965 Mustang alternator

6. Black/White
The last piece of the 1965 Mustang generator to alternator swap is attaching the field terminal (Black/white wire) from the 'F' terminal on the alternator voltage regulator to the 'F' terminal on the generator.

If you want to run an ammeter gauge in addition to the indicator light you can wire it in series with the new 10 gauge wire running from the 'B' terminal to the solenoid.

I'll add a link in the future when the complete article and pictures are up on the site.

Hopefully in the meantime, this will get you up and running.
