That's amazing. I never knew that!

Converting mechanical energy to electrical energy is what the generator or alternator does.

Today's alternators are much better at converting energy than a generator.

However, I would prefer to use an original generator for the Model A as it's correct for the car.

Yup, as long as you spin it ! Spin the pulley that is.

Waste of time and money. And looks wrong.

I prefer the generator for several reasons. The main reason that many use alternators is probably because they have the capability to put out more amps . For instance, if the brighest lights are needed, If you use a 60 amp alternator you can use the 55-60 W quartz halogen kit from Brattons that includes reflectors and can be perfectly focused. I used this setup on our 31 coupe when I used it for a daily driver. Sometimes I didn't leave the body shop untill late at night and brighter lights came in handy. This setup can be had in six or twelve volt.

If I thought I needed more amps than my stock generator puts out, then I'd install a later fan cooled generator. Most people would think it was original because it wouldn't look so out of place like an alternator.

For those who still want an alternator, look at the smaller alternator John Deere uses on their large lawn tractors. I think they would look better than the GM alternators.

The Dog just threw this in the "DISH" for consideration, "Iffen' you got an alternatoror, there's probably LESS chance to have a DAID battery"

thanks everyone,sounds like people like the generator more.i think I will try that voltage regulater in place of that cut out.

To be fair there are three types of regulators out there.

Tom Wesenberg that posts here has one,
There is the one by fun products that is mentioned and a third one that replaced the cover strap by James Peterson

Not to involve myself too much in pros and cons but from a practicable point an alternator is not current controlled. Never seen it. It will give whatever is demanded upon it with respect to engine speed, (no) belt slippage and voltage set point.

Most alts are temp compensated and as the units heat increases the VR voltage will ramp down (current will follow) to avoid boiling the battery.
The battery will determine the current, that and active loads.

Personally given how many miles most drive Model A's and little night time driving, a generator should suffice.

As well it is worth noting that (as least in modern cars) loose belts are far more injurious to bearings than tight belts.
IMHO

In the 10si new technology provides AC actuated VR's that turn on at ultra low speeds.

just some thoughts for those thinking alternator. I use a generator, but I drive less than a 1,000 miles a year in the A.

I agree with Tom re the JD alternator. I do believe the pulley is correct too. Perhaps close enough.
I have a few on A's.

A 12190 is one of the units that can be used. 15mm ID pulley and one wire regulators are available.
15MM=.590
5/8=.6250 or 15.87MM

I have an alternator in my roadster and a generator in my cabriolet. I like the look of the generator more than the alternator, but get concerned about touring with it. Last year on the MAFCA National Tour we had to run our lights during the day for two and a half days, due to inclement weather, and I don't know if a generator would have allowed me to do that. I think I'm going to put a VR on the cabriolet before we leave on a trip to the Model A Ford Museum next month (1,600 miles) and see how it works. I'll report on how it goes when we get back.
