Hi All - This is Mike Hill and I am making Electronic Voltage Regulators (EVRs) for the Model A powerhouse and long-style generators - 6V positive ground. The EVR mounts within the generator case.
The EVR regulates the current to the field coils to maintain a maximum generator output of 7.1V - which is the maximum charge voltage for a 6V battery. At a charge voltage above 7.1V, the battery electrolyte starts to gas off.
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 a few 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.
I have attached a paper which describes the history of Model A EVRs, how they work and why they are beneficial. Any feedback would be appreciated.
I charge $80 USD for the EVR plus shipping (same price as Tom used to charge). I can offer bulk pricing deals to clubs.
I am building these as a hobby to help out the Model A community.

Thanks for your interest, feedback and support.
