ORIGINAL: Colorado_Mustang

1: Remove old alternator.

2: Remove old alternator wiring harness.

3: Install heavy gauge (I use 4 gauge) wire to back of new alternator.

4: Install new alternator.

5: Connect wire from alternator to battery side of solenoid (circuit breaker is good idea. Fuse is bad idea).

6: Disconnect ALT lightbulb in dash (it's annoying).

7: Burn tires.

Different alternators will require different RPM's before actually firing up the charging circuit. Mine will generally not charge until 1500 RPM (engine) on startup, and lower the output below 1200 RPM.
lol burn tires thats good

Maybe a dumb question, but if you disconnect the bulb for the light in a 65, does that also mean you lose the guage function in a 66?

To me the up side of this swap would go toward the end of cleaning up the engine compartment and raising the amount of power available for electrical "add ons", (like a big stereo, etc).

As far as cleaning up the engine compartment goes, using a one wire alternator would allow the elimination of two wires, and would get a person on the right track to eliminate the voltage regulator. It is my current understanding that the voltage regulator serves more purpose than to simply regulate the alternator, but it would be my desire to eliminate the regulator,eliminate some of the wires going to it, and to clean up the wires that must remain.

At some point in the future I will be replacing the externally regulated alternator, I may go the "one wire" route, but I will investigate other types of internally regulated alternators that are commonly available at the local parts store as a fail safe against having to wait for a new one wire alternator in the event of failure.

I would know exactly what to do with a GM product of the same era, but I am going to have to research this a bit with the Ford.

I have had internally regulated alternators in both of my '65 Mustangs, one a v-belt and the other a serpentine. The one in my fastback (serpentine) is from a Taurus SHO I believe and its output is 115 amps.

If you want to try picking their brain on what would fit, I had the work done for both at Astro Auto Electric in Lomita, CA 310-325-1777.
