Delco 10SI Alternator ??

George Rausch · Jan 5, 2012

Everybody may know this, and take this for what it may be worth, but in I&T service manual MF-42, for a Massey 230/240/250, pages 41 and 42 describe how to test and overhaul two Delco-Remy alternators. They look like the 10SI version.

Send a photo of the alternator and we can confirm.

Pretty easy to tell if it is a 10si. If the little plug comes out the back of the alternator it is not a 10si but one that needs an external V.R. If it comes out the top as in perpendicular of the pulley shaft it is a 10si

The drawing in the MF-42 manual of the MF Delco-Remy alternators shows the one BAT connection on the left rear side, the two vertical spade connectors coming up, on top of the rear of the unit, the Test Hole on the right side, and these units have the internal regulator. These look as identical to a 10SI's Ive' seen on this site, as far I can see.
All I was saying was, if anyone is looking for test and overhaul technical info, this might be it.
