This is my second post here. I have a 1982 GS750T (I put the wrong year in the first post). I am currently working through some electrical issues, and wanted to document how I went about troubleshooting using the Stator Papers.
I will try to post the pictures that I took to help the other newbies that might be out there, and to solicit any tips folks have about my current situation.
I replaced my battery with a new AGM model last weekend, and gave it a full charge. Bike is starting well right now.

Here is the DC voltage across the bottom terminals of the fuse block. I measured there because it has read the same as the battery posts in my past tests and I hadn't yet gone through the trouble of taking out the air box to rech the battery directly. Even though the bike has been sitting for a few days, it was still reading higher than normal at 17.3V.

With the key on it dropped to 15.7V.

At idle, it jumped up to 20V.

At 4000 RPM, it went even higher to 22.8V.

The first test I ran was one described in my Clymer service manual, that directed me to measure the voltage from the positive terminal on the starter relay to a ground point at 5000 rpm. That gave me 18.8V, the book says if it is higher than 15.5V to replace the regulator/rectifier (RR). At tom203's suggestion I wanted to check the connections as directed in the Stator Papers.

To get at the battery, one has to take out the air filter box. The only way I am able to do that is my removing the bolts from the rear of the fuel tank and the bracket they attach to. Then I loosen the forward clamp of the short hose at the front of the airbox, then its a tight fit to lift the tank & bracket up and rotate the airbox up and out.

This was the first test to check the connection between the red lead coming out of the RR and the positive battery terminal. Mine measured 0.08V not too bad.

Next looking at the ground point with it still attached to the frame. Mine was screwed in behind the fuse block. That voltage reading was jumping around 0.15-0.22V, a little on the high side. That same lead was long enough to go directly to the negative post of the battery. So I changed that over.
