12 volt conversion for 450

BigJohn · Mar 27, 2009

I have a 56 Farmall 450 gas, and would like to switch it to 12 volt. Was wondering where is the best place to find a conversion kit for it. Also wanted to switch to electronic ignition and wanted to know how to determine the type of distributor and whether it turned clockwise or counter clockwise. Thank you in advance for any and all help.

Here is how I changed my IH 240 Utility from 6 to 12 volts. I had a alternator off a 85 Chevy truck that worked fine. Don't know about the electronic ignition but do the 12 volt conversion first. Get it running and then do the rest if you feel you need to. David.........

Tell the auto parts counter person that the alternator is for a 1977 Pontiac Grand Prix, 8 cylinder 5.7L (350R) engine, with air conditioning and with H.B.L.” (H.B.L. = Heated Back Light–meaning rear window defroster) That will give you a 63 amp delco 10 si, clocked at the 12:00 position. That is the exact alternator I use on my Super M. The wiring can be found on this site, generously provided by Bob Melville. The diagrams are self explanatory, and real easy to follow. As for the ignition, I have a delco upright distributor on mine, but I use points.

A delco 10SI is a tight fit but can be made to work just fine. I use alternators made to fit a 1980 Chev pick up no power any thing. They are around 35amp which is over kill for a tractor. Nice thing is you can get them pretty cheap also. At mu local O'Reilly's auto parts store you can buy one for $35 plus a $10 core and that is with a life time warranty. I have been using that type on all the tractor I convert and they work well and with that warranty if it goes bad it cost you only the time and trip to town to fix the problem

Clockwise on the dist (Looking from back to front of tractor). The Wiring is found below. I will ad that a automotive style fuse link is a great idea installed where the wire to the amp meter attaches to the starter switch. this fuse looks like a piece of colored wire, and is rated like a fuse in amps. It should be rated at 10% over the alternator max output. Wire it in but leave the colored wire exposed. Use mechanical connectors to attach each end to the switch post, and the wire to the amp gauge. Use shrink tubing to prevent corrosion on the connections. A fuse link prevents wiring fires from grounded connections and saves letting the smoke out of the entire tractor. JimN
