Looking at my alternator today and following the service manual check as shown in Fig.68. My connector is flipped from the way it's shown below, with the vertical one on the left side, so I looked at the wiring diagram in the manual that shows the wiring to these connectors and see that I'm supposed to be checking the one that goes to the black wire and the one that goes to the green/white wire. Those measured 0V. I checked the one to black vs the one to white/blue for the heck of it and I got 6.3V. Battery voltage measures 12.5V, and the same 12.5 measured from the alternator (+) connection to an engine ground.
My knowledge of overhauling these things only goes as far as checking brushes and cleaning the rotor. Any pointers on what these readings might indicate will be appreciated. No telling how long since it's been apart, if ever. 1500 hours on it.
