Need a wiring diaghram on how to wire a alternator for 8n tractor, I have it runing but will not cut off with main switch. Had to install a second push button switch to cut it off. As long a the alternator is charging it will not cut off, have to put main switch to off then push the push button to cut it off.

It seems you didn't install a diode to keep the alternator from sending voltage to the coil when the switch is turned off. David...................

In the wire feeding the #1 terminal of the 2-prong plug on alternator (guess it is a 10-SI), you need to insert either a diode or an idiot light (bulb #'s 194, 53, 57, 1815 are all OK). Diodes 1N5551, 1N5404, 1N5408, RS#276-1661, RS# 276-1144, etc. will work). Diode band toward the alternator.
Any of these stops the back-feed from the alternator's exciter diode-trio.

Radio shack diode part #276-1661 works well for that and are easier to find then the one in the diagram or is at least in my area
Thanks again Bob
Where would be the best place to but the diode,also I am only useing one wire from alternator and that is the one you have the diode in.I don"t have a ammeter,will I have to use the 10-ga wire. By the way is the load side the + wire on switch. Thanks again for all the help

'm not Bob, I'm JMOR, Bob originated the picture.
The alternator OUTPUT comes from the stud on the rear with the 10GA wire & the sense wire going up to plug terminal #2........without that you are not going to do any serious charging. Doesn't matter where along the wire you put the diode..where ever convenient. Don't under stand your switch question? Anything taking power from the battery is a 'load', so on your ignition switch, the side of it tahat is hot, whether ON or OFF would be what you are looking for if I grasp your question,
You never said as far as I can tell whether your 8N is early (front mount disrt/right side alt) or late model (side mount distr/left side alt). What is it.?
If still have troubles, I may have a diagram you will see more easily.
Mine is a side mount distributor was told it is a 1952 model but I am having problem finding the wright rotor and distributor cap,I have bought dist. cap and rotor for 8n but they do not fit.
The cap is too big and rotor where shaft goes is too small and made different.
I am sorry about the name JMOR

To the best of my knowledge, these are the part numbers, available from YT (this site). Before ordering, I would talk to them & verify. Look carefully around perimeter of your distributor for ID numbers.
points IGS2224LB and BWD #A81
condenser IAT3076HS
rotor IGP1016D and ECH #AL150
cap IBK1009 and Perstolite #3-129 and ECH #AL165
dust cover IBT1059

looked at picture on TISCO site & it looks like it is held on with screws where the one I pictured was held on with clips. (Catalog pictures are sometimes just "representative".) How is your cap held on? Might want to be sure your clip/screw is what YT has for you.
P.S. Tisco is a distributor, so no telling who makes their parts, so I'm not surprised at the response you got.

Got the diode and put it in line and it worked fine,also could read some of serial no after I had cleaned it, was working on tractor today and the place for serial no had rusted and I could see part of it it looks like 8n169276-245636 the second row of numbers did not start with 8n, I think the moter has been changed,what year did the side mount dist. start in? On plate on right side had no type 4-2524 & serial no 1003-k9cb on left side of clutch housing had nf 32 & 8n-c.1 does any of these no mean anything?

Lots of info on serial & casting number codes on John Smith's site.
