Is it possible in an emergency situation to use a Delco generator in place of an Autolite without changing the voltage regulator?
I used to have a good working Autolite generator but voltage regulator failed and armature shorted out on it. I have a new voltage regulator for the Autolite generator but can only find Delco generators and need the car for the weekend.

I don't think so. I don't have the schematics handy, but I think the fields are grounded internally on one generator and externally through the regulator on the other generator. And that's also the reason for different ways to polarize the generators.

So, generators and voltage regulator need to match? If so, how do you tell which VR to match to an existing Generator?

I'm not so sure about that.....I always thought a 12V DC generator is a 12V DC generator...no matter who made it......Comments?

RDWeaver;
The answer to your question is maybe you can use a 12 volt Delco generator in place of a Autolite.
Delco generators were used on all the V8's from 1959 through 1962 and had their field coils powered from the generator.

Autolite generators which were originally used on the 6 cylinder cars from 1959 through 1962 are a different story.
On the 1959 through early 1960 they the field coils are powered the same a the Delco. Internally from the generator.
According to the Studebaker shop manual all the other Autolite generators had their fields powered from the regulator.

The regulator has to match the maximum current output of the generator along with how the field circuit is powered.

Just give us the Model number of the generator and I have all the books to match the correct regulator.

Thanks, Robert. Traveling but soon as I can will send the model number so as to get regulator guidance from you

I work mainly with 6 volts positive ground, as most of my Studebakers are 1946 to 1952. For these years the Champions used Autolite, and the Commanders used Delco for the electrical systems. I based my answer on the 6 volt positive ground system, but I see no year or voltage was mentioned in the question. It's always best to be specific in the question in order to get accurate answers. I would check the schematic for the car in question to see how the generator is wired.

To be specific the generator was from a 62 lark with a V-8. Autolite #6JP-7402E voltage regulator Autolite VBO-4223FI. The armature shorted on the gen. and all I could find at the time was Delco units so I wondered if they could be mixed. Well it turns out you can't, and I ended up using an alternator so the car has the first modification. Oh well, we used it this weekend on a long trip and was very soon talked into another modification.... AIR CONDITIONING! Turns out I am going to need an altenator.
Thanks for everyone's help anyway It is still a learning process for me.
