Here or the pictures of the diode (bridge rectifier ) that I replaced the cutout points with. No dead battery issues since I did this a few years ago.

This looks like a good solution for my 9N.

How may diodes are needed? You mentioned "bridge rectifier", which leads to think maybe more than one diode is needed for the bridge?

Are there voltage or current ratings on these?

And last, where did you order them from?

Thanks for sharing the tip!

the bridge has 4 diode segments, you only need one of them... depending on what bridge you buy, it's easy to get 25a and 50a models. PIV of an anemic 50 or above will suffice.

Before Voltage regulators cutout relays (points) were used to disconnect the generator from the alltery when tractor was not running. Voltage regulators still have a cutout relay in them.

OK, I'm a little behind here, what are these cutout points to which you're referring?

On recommendation of folks here I did same thing to mine and had zero issues till this winter. Come spring I get to find out where the magic smoke escaped from.

Looks like a neat job Richard.

I've not had problems with my cutouts like I did with my regulators.

But just in case I do, what were the part numbers of those diodes?

They cost about one dollar or less. I ordered five for $.83 each. I have set up a couple of other owners tractors with these.
