Converting 6 volt to 12 volt system

A lot depends on the tractor since some it is an easy thing and on others can be a bit harder to do. Basic things is an alternator like a Delco 10si that was used on say a 1980 Chev pickup no power any thing no AC. Then a diode and ballast resister and the know how to wire it up an of course a 12 volt battery. The big thing is on some tractor the generator bracket can be used to mount the alternator but on others you have to make you own
 
All depends on the tractor make, model, and year.
If it has a distributor or magneto.

More popular tractor models you can buy kits with brackets and wiring or just the brackets. Less common tractors you will have to make your own brackets and wiring harness.

You can buy a universal bracket. I find the universal bracket won't fit anything without welding and redrilling of some holes.
 
On my old red Cub tractor when the 6v battery died, I had the starter/alternator shop rework the starter for 12 volts, and I took home a Chevy one-wire alternator with low output (95 amps?).

Boy, that Cub turned over fast and busted off quick! It seemed like it ran better too. It didn't lug down so bad after that.

The starter/alternator shop did their work on the starter for free because I gave them the old generator.

It seems like the alternator bolted up after I changed some hardware to put in a couple of washers for spacers.
 
Thanks so much for the information, I guess I should have advised, this 6 volt system is on a 1954 International Harvester R-110 with a silver diamond straight six. is there anything that I might have to due in addition to this application?

Thanks for your time in answering my question. This conversion is on a 1954 International Harvester R-110 truck, is there anything that I might have to do in addition for this application.

That should not be all that hard. Did one on a 1951 Chev a few years back and sued the Delco 10SI and a simple diode to keep from back feeding the ignition.
 
You have a truck. You will have to change all the lights to 12 volt. You will have to make your own brackets. Change to a 12v coil or ad a resister to the six volt coil.

If the truck is a positive ground. You might want to get a positive ground alternator.
 
In addition as to what Tractor Guy told you the heater blower motor, will need a resister, to keep it from burning up. If you have electric wipers, they also need a resister. I have had success using the ignition porceline resisters used on early chevies.
