converting to 12 volt

just got the second try bracket bolted on and it works. Boy I wish I would have tried flipping it . Oh well I like the one I made. Now to get the top bracket bent into shape and wire it up.

Here ya go, you'll want a Napa Delco 213 401 1SW it will kick in a lower rpm's than the 10SI so you won't need to change pulleys.

From Federated Auto parts, assume same alternator Yogie listed. USA/7127SE. Tax included $57.55. Remanufactured Delco, converted over to true one wire.

I need to change over the pulley and fan. Goes on a WD Allis Chalmers.
 
finally found the time to get the hood back on and start it up. All is good but two questions. I can not stop the tractor with the on off switch any more. I havn't got the diode picked up and in could that be the problem or did I wire something wrong? Also the amp gauge is peged out to the charge side when running is that normall with a alternator? Thanks for all the help

Some place in your wiring you have the alternator feeding the ignition system - by passing the ignition switch.

Disconnect the diode location in the wire exciting the alternator. See if the tractor will shut off with the wire(s) seperated. If the tractor shuts off - install the diode. If the tractor doesn't shut off - you have a wiring problem.

I have two tractors converted over to 12 volt alternators. Upon engine start up the 20 amp max meter will almost peg out on the plus side. Within a few moments the amp meter will start to lower it's reading - until after a minute or two the amp meter shows a charge of a few amps.

It should drop back, did you use the alt that Yogie sugested?
 
used the one you use Boss and yes Yogi suplied part numbers. I used the wireing diagram sugested several places on this site.

Some will be Politically correct police and have a stroke that you went 12.. Hey IH got smart and went 12 volt alternators too. Further a single wire is cheaper than a generator and regulator, more reliable and takes less maintenance.

I will never understand how people think 12v conversions are "more reliable and require less maintenance." :big give up: Cheaper, maybe. I guess I have seen so many half-a** conversions which included trashed mounting brackets, mangled sheet metal, and wiring harnesses that looked more like spiderwebs, that it has soured me on the whole business...

But, as Brother Dave used to say, everybody to their own kick! :D (And the conversions depicted here are very nicely done and would be appropriate for a working tractor.)
