12 volt conversion

I`m trying to rewire a 8n ford tractor from a 6 volt system to a 12 volt system.I don't know how to rewire it back with a one wire alternator.Can you get me a wiring diagram for it to change it over to a 12 volt, one wire system? Thanks, Joe Lazenby

THe 8N Ford tractor had a positive ground 6 volt system. Changing it to 12 volts you need to change your coil to a 12 volt you need to disconnect your amp guage because you use a voltage guage with an alternator. Put your 12 volt battery in and run the negative cable to ground. Then run your positive cable to your starter solinoid. then run one wire from your one wire alternator to the positive battery terminal. Change all your light bulbs over to 12 volts. The six volt starter will do fine on 12 volts as long as you don't stay on it a lot. If you have to stay on it a lot to start your tractor then you need a tune-up. This should have really been placed in the electrical forum and it would get more attention. Place your questions in the proper forums and you will stand a better chance of getting answers.
