hi guys.. have a 62"farmall 560d running on generator and regulator... want to switch to a one wire alternator system... what do I need to do.. do I get rid of the regulator.. how to I wire everything up... looking for help.. thanks
 
Use the three wire option. A Hitachi 14231. is a smaller version of a Delco 10SI. Easier to fit.
L=#1 S=#2 terminals. The one wire system can lead to issues with battery drain with some, or high RPM to get it operating. The 3 wire just operates like a car.

1. Move the wire from the GEN terminal on the regulator to the BAT terminal. There should now be two wires on the BAT terminal.
2. Take the wire off the A terminal on the generator, and connect it to the BAT terminal on your one-wire alternator.

That's all you need to do.
 
BTW, tape off the one "loose" wire from the generator. It is the F (field) wire, and is not used.

You could optionally move the wire from the F terminal on the regulator to the BAT terminal, making for a total of 3 wires. Then, connect the wire from the F terminal on the generator to the BAT terminal on your alternator.

This will effectively give you a heavier wire connection from the alternator "almost" all the way to the battery.
 
BTW, BTW, it's this simple because a 560 is already 12V positive ground. There is no need to swap wires on the ammeter or make any other changes to the system. You don't even have to change light bulbs!
 
There is an internal regulator for the single wire alternators that kicks in at lower RPM's. The local shop used to do them for me, but he is gone now but any good rebuild shop should be able to help you. Single wire is all I have ever used with no problems of battery drain.
 
I note you state the 560 is 12v. positive ground. I agree with an alternator the odds are it would be negative ground or am I missing something. Jim
 
Going to do this on my 560 diesel but one question do you
need to hook to the switch so it won't drain the battery or does
it kick off on its own?
 
If everything is installed and working correctly, you should not have to hook up anything to any switch.

The 560 tractors were the first one to come from the factory with negative ground electrical system. The 450 was positive ground even after the change to 12 volt.
