  • Who Was Waiting for an EVR?

    I had a few emails from guys waiting for me to make more EVR's. Our summers are so short in Minnesota that I try to make enough of these during the winter to last through the summer. This year they sold out early, so twice I had to make more. I just finished 9 of them for the common long generator. Later I want to put together some pictures of the EVR's and end plates for the different generators found on Model A's. I have to make 4 different EVR's to cover the 4 styles.

    I'll search back through my PM's and emails to find the ones that asked about them, but if I miss someone, I hope they see this message.

    While I never sent you a PM I do hope to purchase one for a long generator and one for a 3 brush Powerhouse. Then depending on some factors possibly 2 for 5 brush Powerhouse generators. Right now working on getting some more stuff lised on ebay to sell as I have more parts than garage to put them in. No room to even work at this point. Rod

      Tom I would like to buy one for a long Autolite generator, this one will be for the spare I bought from Jeff at Bratton's circa fall 1930. Thanks I'll send you a PM

        I'll take 4 or 5 for the long style genny, but no rush take care of the others first. Or maybe one every so often

            Tom, how many amps will those handle? Are they for 6 volt or do you make them for 12 volt also?

              I only make them for 6 volt positive ground Model A generators, but I did a special one for a 1929 Stutz with negative ground, and I made 3 special ones for old tractors with 6 volt positive ground. These are NOT in the output circuit, so the generator output isn't related to the rating of the EVR. These control the voltage feeding the field windings, and the long Autolite style generator field windings have 1 1/2 ohms, so they draw 4 amps at full field of 6 volts. Almost always the voltage is only about 1 to 2 volts to feed the field windings. The long style is rated for maximum of 12 amps continuous output, while the powerhouse is rated for 15 amps, and either one is plenty to run the lights, horn and coil.

              BTW, the powerhouse generators have more field windings, so it takes less amps to full field them. They only draw 1 1/2 amps for the 5 brush, and 2 amps for the 3 brush to full field them at 6 volts.

                Lucky is he who can find or has a 5 brush powerhouse. Nothing is permanent on my car, no holes drilled anywhere and it can always be converted back to complete original. Opps forgot about the rear subframe that can be plugged.

              Hi Tom,

              We had exchanged some messages earlier in the year about the EVR, and the generator in general, over on the "other site". Other than the EVR being out of stock at the time, I don't recall how it was left. I am interested in one.

                Tom it looks like you have plenty of winter work

                  I just hope for Tom's sake, that Minnesota doesn't get dumped on this winter like they did LAST winter,,,, but then again, as long as Illinois is spared!!!! And if they get another brutal winter, the hobby will be rewarded with more of Tom's EVR's!!

                  Took a 6 year old 6V battery from Farm King out of the '36 Pickup the other day that we are running Tom's EVR on in the original generator (6V POS ground just like the Model A) and that bad boy shows it is still A-OK on a load tester, still bright and fresh. In the old days if I could squeek out 3 or MAYBE 4 years I was doing good. EVR definitely helps out does a great job. I like running the generator an alternator just looks weird......................

                Tom, I've saved enough for the windshield frame now, I will start to save for an EVR for my power house tomorrow ! Pat

                Identifying Your Generator
                by Tom Wesenberg
                Over the years generators have been swapped on the Model A's, so now days you can normally have 1 of 4 different styles. First came the 5 brush powerhouse, then the 3 brush powerhouse, then the long generator known as the Autolite style. After Model A production ended and the Model B began, the generator also changed slightly, and now many B style generators can also be found on the Model A. People...

                An EVR saga with a happy ending
                by rheacox
                About 2 months ago I got in contact with Tom Wessenberg about purchasing an EVR for my generator. After confirming the details on the gennerator with Tom, the EVR arrived in the mail very quickly (for USPS anyway).

                I pulled the generator apart and installed the EVR in about half an hour and spun it up with a drill to test, got about .3V at the stud... not good. I got on the VFF to double...

                Power House Generator Question
                by BAAP
                The judging standards talks about three different styles of Power House generators. The two earlier versions had 5 brushes and the one later version had only 3 brushes. I've been asked to look into having the black bakelite brush holder plates made. I've talked to one of my sources and he said that it would be no problem making it. Before we spend a bunch of time on this project we have a question...

                by SeaSlugs
                I have 2 of these cutouts on some model A generators. Both are Ford script and one has a stamped B (not sure on other) I read the JS and they say all model A cutouts had slotted mounting tabs - these 2 do not. So what are they to? Model B's? Sure are heavy....

                After several interruptions this summer, I finally have some electronic voltage regulators ready to mail. The most common generator is the Autolite style, which is the common long generator, so those are the first ones I finished. Now I need to finish the other 3 styles, which I also started earlier this summer. Those 3 styles are the 5 brush powerhouse, 3 brush powerhouse, and the later post Model...

                generator armature taper differences

                I took the generator off of our '28 Coupe to the local shop to be repaired, and the guy is experienced in Model T & Model A generator and starter rebuilds but he ask me a question that I could not answer so I will ask it here.
                Will Model A generators with the two different tapers interchange if you use the complete generator, pulley included? The armatures will not interchange from one...

                Model A Generators
                by gdaquilina
                The generator I have on my Town Sedan now has an oil cap on the front and rear plates with bushings on both ends. The output connection is on the rear of the cutout and two wires exit the output connection. Am I correct in assuming that this is maybe an early V-8 generator? If it is, is their any difference in its output from the Model A ones? All internals appear as the parts diagrams show for...

                Generator output post location
                by Jeff/Illinois
                All Model A fine point cars that I've observed (post Powerhouse gennies, 1929-1931) have the output post on the generator towards the 'back', away from the front of the car. Seems like I've been noticing more Model A's anymore that have the long Autolite generator with the output post on the front near the radiator, so the cutout relay is mounted 'backwards'.

                I realize that the generator...

                Another Generator Shipping Warning
                by Tom Wesenberg
                This generator came the other day, and I have no idea what fell out before the postal worker taped it shut after they tore it open. It would be interesting to go along the whole trip to see just how they can do so much damage sending a package from point A to point B.
                Anyway, this is why I say you MUST make the generator completely non movable inside the box. Loose Styrofoam, peanuts, or a few...
