MF 175 DIESEL

[Rls731]

I've decided to convert the alternator on my Massey Ferguson 175 diesel tractor to an alternator with and internal regulator. I've been looking for a wiring diagram for this but all I can find is for a 175 gas.
Does anyone know where i can get or share a wiring diagram for a MF 175 diesel with an alternator with internal regulator?

Brand of alternator?

One or three wire?

Using ammeter or voltmeter?

These things can make a difference in the wiring.

It's a delco remy one wire with an ampmeter

This modified drawing should work. I don't think the MF 175 ever used a Delco internally regulated 3-wire alternator, much less a 10SI 1-wire which is actually an aftermarket modification, not a Delco build.

Im having the existing 10dn rebuilt. The rebuild person told me he would convert it to an internal regulator and eliminate the 2 small connections.
This is the alternator as it was.
I don't have the rebuild back yet. Im just trying to be prepared.
Thank you for your help

I can only guess you will only need to connect the one battery wire going to the ammeter. He will be the one to tell you for certain where you make the connection(s) on the alternator as he rebuilds it. The common Delco type one wire alternator is built from a 10SI model, not a 10DN.

Ok thank you

On most MF diesels switching to a one wire regulator for the alternator is unnecessary. The oil pressure switch that supplies power only when oil pressure is present can be used to power up the alternator.
