Delco Alt. 1 wire to 3 wire

Posted by SuperA-Tx on February 14, 2007 at 15:44:24 from (4.227.107.121):

Cousin converted my Super A to 12 volt back several years ago and used the Delco 10SI Alternator. It is wired like Image #11 on Bob's wiring diagram page, I ran all new wires. I had to put a smaller pulley on it to get it to excite but after that it works alright although I still have to rev it up sometimes to get it to excite. A week or so ago tho I was reading here that the three wire system is lots better. On Bob's site theres a diagram for Farmall Super H (image #6) that uses the Delco 10SI Alt but has the three wires. I see no differance in the two diagrams other than the extra two wires off the 1 and 2 posts on the alternator and the added "warning light". Is there a reason I couldnt just add the two wires and the warning light to my setup thus converting it to a three wire system?

Would something have to be done to the Alternator other to make it work other than what I have mentioned?

Plus I saw in a post where you could use a diode in place of the warning light. Can someone tell me a little more about that please.
