Externally Regulated Alternator to internal reg?

The old Motorola alternator on my 304 ('74 CJ5) is making lots of noises. Rather than re-bearing it, I was thinkinga bout using the alternator off the 360 I have sitting around that came out of a '79 Cherokee Chief. I remember a post last year about externally regulating a normally internally regulated alternator, but can't find the post now.

So my question is, how can I make this work?

Thanks!

Re: Internally Regulated Alternator to internal reg?

Why not just wire up the internally regulated alternator as it was meant to be used? You probably only have to make two connections, one for ignition on power and the other to the regulated point in the harness. You could leave your old harness as is, if that's a concern.

Re: Internally Regulated Alternator to internal reg?

Gotta ditto Tim's comment. I went with a Delco alt. which was super simple to wire and was able to ditch the all the old motorola junk & 9 miles of associated wiring.

Besides cleaning up "the tangle", it makes troubleshooting something a kinder-gardner can understand.

Look at THIS post. You can do the same thing, just get rid of the external regulator. It will make life easier in the future. That way you can get an alt. from anywhere without looking for an early delco or prestolite.

Re: Internally Regulated Alternator to internal re

Thanks everybody! I'll look at just going doing away with the external regulator. Got both alternators in the shop now. The old Motorola is noisy, the main reason I'm looking at getting rid of it. Unfortunately, I'm not sure the Delco I pulled off the 360 is any quieter. However, both work. I'm thinking I might see if I can re-bearing the Delco and go from there.

Thanks again!

Re: Internally Regulated Alternator to internal re

Well, it's a moot point. Both the old Motorola and the Delco are toast. I'm just gonna swing by Car Quest and pick up a replacement for what I got...though I can get one that runs 55amp instead of 37 amp.

Thanks for all the help guys! I really appreciate it!

Re: Internally Regulated Alternator to internal reg?

I'm going w/ the Delco tomorrow. I lost my charging system today and have been digging through wiring diagrams trying to figure out what would be better than spending $25.99 on a voltage regulator when I don't even know if it is the bad part!

I'm only seeing two wires comming from the Delco (on the diagram) one to the solenoid and one to the dash pannel. That's all me!
