Voltage regulator for generator
Which voltage regulators are currently available? I am not asking about the cutout with a diode. I do not see any regulators in any of the parts houses books that I have. What is currently available and where can I get them?

Re: Voltage regulator for generator
The FunProjects regulators have been the most popular, sold by several vendors, but the chip used in them has been discontinued, and no more are available. Tom Wesenberg has had a generator mod for 6V positive ground that many have installed, but you'll have to contact him for availability.

Re: Voltage regulator for generator
Toms EVR works well, actually works great. But it needs a good cut-out to go along with it.

Re: Voltage regulator for generator
John Regan's Fun Projects regulator uses two shottky type diodes if I remember correctly. This is for the one way current flow or cut out. The other components use high speed switching to turn the generator on an off for amperage/voltage control. There is not much in there but what is has to do the job. A lot of electronic components that used to be made here in the USA are made overseas now. The CVD 19 situation may be preventing shipments or manufacture of things but I don't know. I also don't know how well the Birdhaven folks have been keeping up with this stuff since they purchased the rights. I would call them to confirm no availability problems.
They are a decent little regulator set up but they are sensitive to amperage or voltage spikes and can be easily damaged if the operator isn't careful. A person should make sure the engine is off before disconnecting the battery and I don't know it the units can take a jump start or not. The low battery can damage them due to too high a charge rate with low voltage. Last edited by rotorwrench; 07-09-2020 at 06:18 PM. |

I'd bet that he is out of them, and not making any more at the present time. He has a lot of projects in the fire right now. They sell out fast whenever he gets the time to make some up. |

Re: Voltage regulator for generator
Tom's EVR's work great.
Your generator is converted to a 2 brush and his EVR is a true regulator of the field current. I have theming both of my cars. Chris W |

The Funproject type regulator has been on back order/out of stock way before the C19 thing.
