Found this alternator harness a while back at Speedway Motors when I converted my 56 IH truck to 12 volts. Used the same thing on my 54 NAA just yesterday, makes a nice clean install. Was an easy install but a little pricey.http://www.speedwaymotors.com/Alternator-Wiring-Harness,2373.html
One thing I haven't seen mentioned or I just missed it in the conversation is the pulley on the alternator for the 5/8" fan belt. My 10si alternator came with a 1/2" pulley.http://www.ytmag.com/AFD5035_22526.htm This post was edited by KrisNMo at 21:49:17 01/14/13 2 times.
