The 2N has a charging issue (I think)per the comments from the guy who dropped it here. I am going to get into electrical soon and want to try to understand it before I start pulling at things. The blurry item in the picture, in front of the air filter and to the right of the red cable. Is this a "cutout relay"? It looks like a solenoid with a little arm at the end of it that has a contact point on one end of the arm. There is a piece of bark....yes, bark from a tree...wedged under the arm opposite the contact point. I was told to keep the bark there or the battery would not charge and also to disconnect the ground when shutting down to prevent discharge. Any idea what he was talking about?

Dear 6n I have a Fun Projects voltage regulator on my old 2N and I like the way it works. After start up it charges around 10 amps. Within a short period of time it tapers back to 1 or 2 amps, just like a real voltage regulator. With your old cutout, it just charges at the same rate all the time. If you set the screw too high on the back of the generator, then you boil your battery. It works by only letting through the current that the battery needs. Once your battery is full, it will not allow current through. The bottom line is, they seem to work great and mount exactly like your old cutout. I think I bought mine about a year and a half ago. B.

There is a small diode that you can get for the old Model T and Model A Fords that will fix that cut out you have pictured. You just have to solder it in there and snip a few parts. Basically you are getting rid of the points in there and you never have to worry about them sticking when you shut the tractor off(witch will kill the battery) this part is only a couple bucks and it is the best part I have ever bought for my Fords. The new cut outs are JUNK and will stick on you all the time. I have even bought one that was stuck allready from the factory. I was pulling out my hair untill I found what was going on. I bought 3 brand new ones in a row and none of them would work. You can get that diode at www.snydersantiqueauto.com They have a phone # if you have any questions. Nice people to deal with.

Yup, that's the innards of the infamous generator cutout relay. It's basically like an on/off switch that unhooks the battery from the generator when the battery is fully charged to prevent over charging. You'll definately get a new one. I would suggest going with the "Fun Projects" stealth Voltage regulator that sits in the same housing as the cutout so they look identical from the outside. They're about $70, though but worth it.

Voltage regulator use 3 or wires. It needs a field connection. How does that stealth vr get around all that, or does it?

Rob..... ....the "stealth" 2-terminal voltage regulator uses some specialized voltage sensitive solidstate stuff to connect/disconnect the 1-terminal 3rd brush genny from the battery. Set yer 11-amp 3rd brush genny to max charge and let the "stealth" voltage regulator "switch" on/off the genny to the battery to optimize the chargeing rate for the battery. Works slicker'n snott and well worth the $70 cost..... ....Dell

$70 voltage regulator? Ouch! There is a cutout on this site for $16. I am afraid I don't know the difference yet. If the VR is a lot better and will make the tractor more reliable I am happy to go the $70. This is a 6V posi-ground system. I am going to rewire her soon. You guys tell me the way to go and I will start looking at how to do it. Opinions always welcome.

The original part is called a cutout. Sorta like a relay that lets the electricity go from the generator to the battery so long as the battery voltage is less than the genny output voltage. I got the original part and put it on my tractor. The only problem is the points that make/break the circuit have a bad tendancy to stick. My brand new part is no longer working. The Voltage regulator is a much more robust and accurate version of the cutout and is hidden inside the metal box so it looks exactly like the original. Whenever I get around to replacing my cutout, i'm going to go with the stealth VR. Here's a link.

BTW, these are intended for use on 6V systems, not 12V conversions.

Jeb2N, The web page makes this claim...[Quote] true field winding control (not just a diode) and protection from electrical system[/quote]

That statement may be false or misleading unless a connection exists between the reg & the Field Winding... because the field winding on a 9N (3rd Brush) is hard wired internal with the Field Current Mechanically (screw) adjusted.

That doesn't mean it won't work but I suspect its an SCR devise with some type of circuit that provides current control between the GEN Output & Battery.

My heavens, Phil, I can't understand half what you just said. Can someone say it in "newbie" terms?

That looks pretty awesome. If it is indistinguishable from the outside, why not? It sticks with my goal of making the tractor look original and be reliable. It's a little pricey but this battery issue is getting old. I saved the link and will order one when I get to that point....which I hope will be soon.

Might be charging to the wrong voltage. Is it oak bark, or pine?

Yes, that be what"s left of a cutout relay.

It WAS pine originally but I upgraded to oak the first week I had it. Nothings too good for MY tractor.

I'm SPEECHLESS! I thought I'd seen about everything it was possible to see done to these 'ole girls, and this about tops 'em all. And then people wonder why it doesn't charge, battery goes dead, or all the smoke leaks out of the wiring!

You think that is bad? The sparkplug wires look to be about six feet long so he criss crossed them all over the engine, took them outside and wrapped them several times around headlights and then secured them with zip strips. The only place they did NOT go is thru the tube that I THINK they should be in.

So you got it where the headlights are tied on with the spark plug wires.

Interesting, double duty. Do the headlight flash like a strobe or do they get 6v too?

The sparkplug wire thing sounds kinda BIZZARE! Are you going to post BEFORE and AFTER pictures?
