Model "A" voltage regulator
 

a company on the Internet, and at least one parts dealer, advertises a cut-out that looks like an original but functions as a tue voltage regulator. Does anyone know anything about these?

Re: Model "A" voltage regulator
 

I'm a relative newbie (bought my Town Sedan just over six months ago), but one of the changes I did was to get one of these, after noticing that my battery was being overcharged during regular driving (generator is set to 10 amps; the overcharging symptom was acid leaking out all over the place). For awhile my workaround was to drive with the headlights on for the first half of any trip I was on (resulting in a 10 amp discharge), then turn the headlights off when I judged I was around halfway through the trip.

No more overcharging, and the stock look remains - couldn't be happier with it. Just have to remember to notify anyone working on the car that you have it installed, in case they feel like polarizing your generator.

There are actually three types for sale.

Fun Products makes the regulator that looks like the cut out.
Tom Wesenberg makes one that mounts on the internal end cap
James Peterson has one that replaces the generator band

Actually its Fun projects!!! Not fun products, an easy mistake but fun products is a different company that sells a completely different product.

I use the Fun Projects can style regulator and love it. It installs just like the cutout but gives voltage regulation similar to modern cars. They have them in 6,8 and 12 volt versions.

Group,

What voltage does the regulator for a 6 volt battery use ?

The 6 volt regulator would be used with a six volt battery. The 6 volt regulator is for a 15 amp maximum charge. You need to remove the generator band and adjust the third brush for a 15 amp max . Then you can remove the cutout and install the regulator in its place. Its just as simple to install as the cutout.

I have used two of those regulators that fit inside the cutout can for several years without any trouble.

Let me try again.

To charge a 6 volt battery, what voltage is the "6 volt" regulator set to ?

Mine will put out about 7.9 volts when not connected to a battery. When the EVR is connected to a battery, the battery will load the charging circuit and lower the voltage to a few tenths over normal battery voltage.

The is not a simple answer to your question

Fully charged the voltage will be at about 2.25 volts per cell, a six volt battery has 3 cells so the voltage will be about 6.75 volts. To charge a battery the voltage will need to be over about 7 volts. Please note voltage is not what " charges " a battery current is what does the " charge ". Here is a url that may help you understand battery charging. http://batteryuniversity.com/learn/

Re: Model "A" voltage regulator
 

I have the "regulator in a cutout can" from Mac's and it works flawlessly. I set my 3rd brush current to 16 amps, using a digital ammeter. I can run headlights for a couple hour drive and never have had a low battery issue. My typical charge current with a fully charged battery tapers off to around an amp or so. (thats reading from my old analog gage in the car, not too accurate...) When I am running headlights on low beam (21/50 bulbs) I am about on zero, with lights on high beam, just under zero a bit. I should hook up my digital ammeter and check to see what the readings really are but I've never had a problem so haven't done it yet.

Re: Model "A" voltage regulator
 

Sorry to say, I'm afraid you're out of luck.

James Peterson started offering his EVR about the turn of the century and sold many. i haven't seen any recent information concerning him; since it has been over 20 years I'm afraid James may no longer be with us.

A few years later John Regan created the FunProjects regulator, a simple replacement of the cutout. Because the main component in it became obsolete, he stopped producing them a couple years ago.

At some point Tom Wesenberg entered the fray with his design, which is quite good. Unfortunately for Tom, he lost just about everything in a house fire a couple months ago, and is unlikely to be producing them again any time soon.

Tom has said that he really wants to start up his generator work again, but yeah, it might take 1-2 years for him to get his ducks in a row.

Try Nu-rex out…

Their system has a heat sink to cool the diode.

Thanks for the explanation….
