Anyone Making EVR's Today?

I did a search and came up empty handed.

Has anybody taken these over since Tom Wesenberg died?

Thanks I think mine has given up the ghost.
 
search posts by Steve Blancard, he is a generator genius! he's also on facebook. all types of Model "A" and V8 styles.
 
Steve Blancard's name here is ndnchf. He's the one who rebuilt my generators and put the Eva's in them.
 
Jeff Stevenson & Lori Adams in Idaho recreated and are selling a Fun Projects type of Regulator (inside the cutout housing); but looking at their website, the 6V Positive Ground variant is out-of-stock (all others show in-stock: 12V + & - Ground, 6V - Ground)


They have a Contact Page on their website as well: I'm sure if an inquiry were sent, they would tell you if/when they plan to have more 6V +Ground versions available.
 
Jeff - please email me at hill.mf@gmail.com and I can send you a procedure for testing the Electronic Voltage Regulator (EVR).

I build EVRs for the long-style and Powerhouse 3 and 5 brush Model A generators. The EVR regulates the power to the generator field coils to maintain a constant output voltage of 7.2V which is the maximum safe charge voltage for a 6V battery. At a charge voltage above 7.2V, the battery electrolyte starts to gas off.

The EVR removes the need to adjust the third brush setting and worrying about too high or too low a charge rate. The EVR preserves battery life, mitigates cable/post corrosion and maintains the original and authentic look of the Model A engine compartment (versus a modern alternator).

The regulator I sell is the same basic design that Tom Wesenberg sold for over 20 years and is based on a well known voltage regulation circuit. I have made additional improvements. I give full credit to Tom for his ingenuity and for all the help he gave all of us in the Model A community over the years.

Steve Blancard refurbishes generators and has EVRs to install. He also has 12V negative ground EVRs for 12V generator applications.

The Stevenson version of the Fun Projects Voltage regulator shunts/shorts the generator output to ground. This also means that you will see your ammeter fluctuating from a low to high charge reading. They are very susceptible to damage if the cutout is subjected to reverse current (polarizing the generator). My understanding is that a 6V positive ground version is not available. There is more information available from Jeff on this forum.

FYI - here is Mike's EVR installed on a 1930-1931 model A brushplate.

Back in the day we used the separate Ford regulator that was used on later cars. It had three connections: B for Battery, F for Field, and G for Generator. The B went to the battery, the G went to the output pole on the generator, and the F went to the field coils instead of the third brush. For those of us who did not care the regulator was mounted on the firewall. For those of us who wanted to keep the car looking original the regulator was hidden and the extra field wire run in the woven conduit. The regulator has to be grounded.
