Alternator that looks like a generator. Is there such a thing.
I have a passing interest in the older Fords, the flathead V8 and the Y block engines.
In my limited experience with the generators and 6v, I was wondering if anyone has made an alternator that looks the same and replaces a generator. I suppose an alternate solution would be to gut a generator and fit an alternator into the generator housing. NE |

Welcome aboard! Yes, one such company is E. J. Whitney Co., Inc. in California that does generator to alternator conversions. https://ejwhitneyco.com/automotive.html

Speedway has them among others.
If you fix the issues with your original equipment you should be good to go. My ‘41 is still 6 volt with a generator and it’s still chugging after 83 years. |

Re: Alternator that looks like a generator. Is there such a thing.
The PowerMax looks like a generator but is about 3/4" larger diameter than a stock generator. I did not last long. I took it to a generator shop who figured out that the polished aluminum generator-looking housing contained a small alternator from a Japanese car. They found a suitable replacement alternator to fit in its place, and that has been working okay for about four thousand miles.

I have a Whitney 12 v alternator on my roadster. He uses an original case and bearings so it can safely support a fan. Makes 6 V too.

Re: Alternator that looks like a generator. Is there such a thing.
No personal experience but I have heard the alternator/generator look alikes don’t vent effectively therefore prone to overheating and failure. That’s the reason I decided against one for my 33.

Re: Alternator that looks like a generator. Is there such a thing.
I have a powermaster on my '47 and a Whitney on my roadster. Both perform well but I must say the Whitney is much more convincing looking. It uses a factory rear plate and the front mount and pulley look original. I have a generator on my '40 and that works fine aswell.

Re: Alternator that looks like a generator. Is there such a thing.
I have a Powermaster 82016 6V Neg. ground on the 59AB in my '46 Coupe. It has 5000+ miles on it with no issues so far. I have kept the original wiring and regulator in place, and had the generator rebuilt for spare. Will likely change back to the gen. if the alternator goes south.

Re: Alternator that looks like a generator. Is there such a thing.
Yep The original 33 generator I had on my early 34 fordor had no built in cooling vanes at the front -Whitney refused to make an alternator using the 33 casing due to the risk of overheating -We used a 34 generator casing with the inbuilt cooling vanes and it has been going strong for 6 years

Re: Alternator that looks like a generator. Is there such a thing.
I have a '32 roadster that has an original AC Delco generator that has alternator guts, the car is not proper for here as it has a Buick nailhead and is a highboy. The conversion was done by GenerNator and has worked wonderful for about 10 years. You might want to check their website.

Re: Alternator that looks like a generator. Is there such a thing.
I don't think anyone would argue that that an alternator is not a technological improvement over a generator. But for how most people drive these cars today, the question is - do you really need the technological improvement? Especially today with quality LED head and tail lights. The extra current available from an alternator may not be needed. For some it is, I have no problem with that - to each his own.
I rebuild original Ford generators just for fun, I know them pretty well. They are very high quality. When properly rebuilt and set up correctly, they will provide many years of trouble free service. This is an example of one I rebuilt recently. Last edited by ndnchf; 01-10-2024 at 04:31 PM. |

Is there any way to rework a '41 6v positive ground generator to put out 12v negative ground? With a proper regulator, of course. Or does anyone sell such a generator/regulator combination? |
