Before I got to reading 8n discussion pages I purchased for my 8n tractor a dixie A-1133-1w, 12 v 63 ANDR, 1 wire alternator, which is what the local auto supply store advised. It has never seemed to charge properly and my battery constantly needs recharging. The literature I'm reading indicates I should have purchased a GM 10-SI alternator and used a different wiring pattern. My question is this. My alternator has the same male plug as the GM 10-SI however I am not using any part of it. Could I use the plug and the wiring diagram suggested for the GM alternator. Also the dealer told me that if an alternator is charging, you can put a screwdriver up to the back of it, and it will be magnetically attracted. Any truth to that, mine doesn't.

I do not think that one wire alternators are your best choice since you have to rev them high to get it to start charging. The Delco 10 -17 SI series is the popular choice. (Not that popular translates into prudent. In this case it does)
N-Series has a good wiring diagram.
The screwdriver trick only indicates that the rotating field is ernergized and not necessarily charging. I have never done this and do not ever intend to. (To me this is a meaningless test) If the plug physically fits, use it... P2 goes to the bat terminal and P1 goes to the ignition through some kind of isolating device. See posts below.
Happy Motoring

Question Claus,
I also have the one wire alternator and as you say it takes some engine speed to get them charging. I have been considering a smaller diameter pulley for it. Wouldn't this solve the problem?

Is it really a problem? I have had a one wire Delco altenator with no energizer circuit on my 51 for 5-7 years. Yes it does not charge immediately after startup but I have never had a low battery. I used to worry about it and watch it all the time. After watching for a while I now know it always comes on in the first couple of hundred feet of movement. I don't even think about it anymore.

The 1-wire versions can work. Some people have posted about problems with getting them to startup reliably. Your mileage may vary.

Considering just how little additional work is involved in using the standard 10SI, using the the 1-wire version doesn't save much effort. Then consider that if you're using the standard 10SI, you can get good ones pretty cheaply if you visit a salvage yard.

It helps, but then you need to start looking at your belt the, sharper the turn - the more flex inflicted. It will cause the belt to wear and you will need to replace more often.
