I have a 1951 8n and I can"t seem to locate the voltage regulator. I looked all over the "firewall", but nothing there. 12V battery, looks like neg to ground (he used the positive "red") wire and hooked it to the chassis. Ameter wires have been snipped also. This appears to be a rigged setup. The thing is, I bought this tractor 5 years ago, and have had no problems until now. I"m replacing the starter relay for now, after jumping past it. The relay still chattered, so i thought this was a good place to start. Also charged the batt and cleaned all connections. I was looking for the voltage regulator to do Tip 23 with the screwdriver. Question is: Can these really run without the regulator ? Do I need to polarize anything?

Most likey you have a delco 10SI alt with the regulator built inside.

How many wires does it have? One or three?

Glad you figured out the difference between an alternator & a generator.

If you tried tip # 23 on an alternator, your next lesson would be replacing it.

Check out tip # 39 too. A set of manuals could save you a lot of time & money.

if you try a magnet on a generator it will stick to it but it will not stick to an alternator since alternators are aluminum. This statement is a copy/paste. It appears to me that the housing is aluminum. I can"t look until Friday, as I will be coin" that farmer thang tomorrow, and helping another neighbor.
Btw is the copy/paste an accurate statement?

12V conversion most likely has a internal VR in alternator.

Just ran out to take a peek. Took my trusty neodymium magnet along, and the only magnetism was where the canister split. The only ID was a stamp "Delco Remy". The length and diameter are appx the same (4"). Also looked up Delco Remy for 8N's, and the alternators look like what I have.
BTW.........Thanks to all.
