Question alternator problem

Yup, I know, I should be able to find what I need in search, but I'm impatient........

The alt on my 67 has been converted to a 1 wire and I need to be reminded where to insert the screw driver to "full field" it and bypass the regulator to see if that is the problem.
The wiring wasn't the same as the conversion I found in search so I changed it but I'm thinking the PO killed the regulator. I would rather change the regulator than the whole alt. I've dumped enough money down this blackhole.

Thanks.........

Re: alternator problem

Not sure about that test but I have a suggestion. Do you want some advice? Good. Grab a book a learn about these things. Simple stuff. You'll be able to fix your own for just a few bucks and easily too. Since an article in Hotrod about 30 years ago, I haven't spent more that $5.00 rebuilding alternators, friends included. That is, until my wife bought her damn Porsche. But that's gone! Whew.

That was damn funny.

Well this is what you get then.

Re: alternator problem

On a stock unit there used to be a "D" shaped hole you put the screwdriver in. I'm not sure if it's still the same as a one wire.

The purpose of the test is to determine if the regulator is bad or possibly the diodes or brushes. I have been rebuilding my own alts for 40 years......I just can't remember where to insert the metal probe to bypass the regulator.

If you can buy an internal regulator, set of doides and brushes for $5.00, I want to know where that is.

Why doesn't the Hot Rod article tell you how to do a simple test ........

Re: alternator problem

It might have. I don't remember. It didn't apply to my setup so I didn't log it into my memory banks.
Oh, parts. I've got a great local shop that I've buddied-up to for a long time. But before that I would just replace individual diodes after testing them with a meter. Original early alternators have replaceable individual diodes. And brushes are about a nickle in this part of the country.

Thank you.........

This is the kind of response that HELPS someone when they have asked for it. I did locate the D shaped hole, but it was inaccessible on the car. I removed the alt and re"clocked" it to get the hole where I could access it. The alt did charge when I did the test and actually charged from then on.....until I turned the engine off and restarted it. Then I needed to short it out to get it to charge again. Does it sound like a bad regulator or is it "converted" wrong. I did change the wiring from what the PO had(rats nest!!) to match this one https://www.camaros.net/techref/ftecref14.html in a tech article I found in search.

You both need to re-read this...https://www.camaros.net/forums/showthread.php?t=102610

Your posts are exactly what Dennis was addressing and trying to eliminate. They weren't helpful or appropriate and were only meant to be condescending. I attempted to inject a little humor into the thread by saying I'm impatient and got it thrown back in my face.

If you can't say anything nice......don't say anything at all.
