I did mention an A circuit type Delco Remy. I’ll double check. As for the amperage, I think I looked at the pictures that Inairam had posted of his. I will ask them for clarification. Would I be wrong in assuming that’s the maximum amperage the voltage regulator unit could handle? The generator will be the limiting factor? Thanks

Steve if I understand your question, there is a maximum output for the generator. Generators intended for lower output applications are constructed somewhat differently than a heavier built version that is intended for more output potential. On the website that you posted they use the term "fling the solder" I believe it is. Basically that means you can overwork/overheat a generator with excessive output and it will get so hot that it comes apart. At least to the point that it is ruined.
If a tractor only has a few lights and a battery ignition, along with a good battery, a high output charging system isn't needed.
Also looking at that website from what I saw their regulators are A-circuit.

Most but not all 6 volt generators are 3 brush units. The 3rd brush limits the maximum current the generator can deliver. On the older units with a cut out the 3rd brush was adjustable, but on ones factory equipped with regulators the 3rd brush was usually fixed. I believe the very late 6volt generators may have had just 2 brushes, as well as the 12 volts, and with those you need a get a regulator matched to the generator
If you are not part of the solution,
you are part of the problem!!!

I did the checking on dvr4p some 2 years ago when I found out Clover is out of business. I am pretty sure I posted it back then. I picked the highest output offered because the service manual says the max cold amps for some of the 6 generators are 20-25 amps and they settle done to 16-19 amp when warm.

They are A-type regulators, available in 6-volt positive ground, and they have been field-tested on cubs in the US by me.

There are also smaller and more easily fit inside the regulator shell than the clovers.
When you only have 9 horsepower you need to know the names of all of the ponies!

Rekindling this older thread. I am in contact with Peter at Electrodynamic Solutions on the DVR4P series of solid state regulators. I need to replace the mechanical unit on my 51 Cub. It was replaced previously with a low cost overseas manufactured electromechanical unit back in 2008 and is now failing. Peter is recommending the DVR4P-6-11 (P=positive ground, 6 volts, 11 amps) regulator which seems to make sense. I did see on this thread the DVR4P-6-22 which is for charging capacities of up to 22 amps. Folks with experience with this unit, is the 22 amp unit correct or is the 11 amp unit ?
