Bob M said: (quoted from post at 12:58:29 06/17/13) Filo -

You will be better off using a 3-wire Delco (10SI series) alternator. Will cost less, charge better at startup and is less likely to run down the battery if the tractor is not started for long periods. Also will properly operate your idiot light (a 1-wire alternator will not).


Wire up the 10SI as follows:

- Large wire to the alternator BAT (output) post

- Relocate wire from the #4 terminal on the old VR to the #1 aux terminal on the new alternator.

- Connect a jumper from the new alt output post to the #2 aux terminal.

Cutoff/tape all other wiring at the (unused) VR plug.

This is what you currently have for wiring on your tractor.

The only problem you may encounter using Bob's solution is that if your light bulb fails the alternator will not start to charge. A resistor of equal or greater value than the light bulb connected between the #3 and #4 wires at the regulator will overcome this problem.

The #4 wire can be connected to the #1 or F terminal wire at the old regulator and then use that wire to connect to the #1 terminal on the alternator.

Bob is explaining how to wire up a 10SI 3 wire with internal regulator. For the dash light, I would use an LED with a 15 ohm resistor as a shunt across it to make it charge. Jim

Jim - Your solution will work too.

But presuming the OEM alternator is a 10 DN, the existing idiot light in the dash will work "as is" so long as it is wired as in my previous post.

Also - depending on the vintage of the tractor, a 15 ohm idiot light bypass resistor may already present in the form of a resistance wire in the dash harness.
