switching from generator to alternator question.
I have a 64 f-100 with 223 I6. The generator is making some bad noises and does not produce any power at idle (put in volt guage).
What year alternator will mount up to the existing bracket and what other parts would need to be purchased to change to an alternator. Also I will want a high output alternator since I plan to add some other add on electronics to this truck down the road and don't want a lack of power being a problem.
Thanks for the advice,
PS: I tried to search for this first, but the search feature was down due to high user volume.

I am not aware of any alt. that will bolt up to the generator brackets without some adapting/modifying of brackets. Usually all that is needed is to fab a spacer to take up the space between the generator pivot mounting brackets and then lining up the pulley. Sometimes a different adjustment bracket might be needed, it depends on the angle of the present one. A modern internally regulated Ford or a Delco one wire(Ford version also avail.) alternator would be the easiest and also produce about 2-3 times the output of the generator.

Ok Guy's, I've done this conversion to my 64 with a 223 engine.Read the tech article it will show you how to wire it up.I went with a GM one wire and a bracket from a local auto parts store.You will have to use a dremel tool to elongate the holes so, you can get the pulleys to line up.It works great and is easy to do.

a company called wilson sells pulleys with a large offset of the pulley groove and a L shaped bracket that allows you to use the generator brackets when going to a alt system. i have used these kits and have to say that the workrd fine for me. the company is based outof winnipeg man. canada.

the 79 through 81 series of Ford cars and trucks had a 100 amp alternator option that uses the same offset, pivot mount, and wiring as the earlier alternators. it uses the same voltage regulater, too. It is physicaly larger, so a custom adjuster bracket will be needed. I modified a standard GM one.

Minishtr,
I seached the articles and only came up with the one for a 352 engine. Can you post the link?
Thanks for the responses. Changing out a pully and getting an aftermarket adapter sounds like the way to go. If I go with the one wire alternator that has an internal regulator, do I run the wire straight to the battery side of the silanoid and get rid of the big regulator on my fender?
Any pics greatly appreciated.

That's the one.You just need the wiring diagram.No need to change the pully if ,you go with the GM alt you get rid of the regulator on the fender.I have some pics some where I'll see if I can find them and the big wire goes the the battery side of the silanoid.If you wire up the alt. light you will notice it dosen't go untill you rev the engine.

The article is here in the tech article section. The wiring is simple; one from the battery post on the alt to the + side of the starter relay. On the plug short red to the battery terminal, white to nothing or to the alternater light. You can leave the Ford wiring in place or remove it. The alternater you need is a Delco 12IS.
