Place your meter on the battery at an angle you can read it and have your hands free. Make up a jumper wire about 4 feet long with alligator clips. Attach one end of the jumper to a good clean ground. Use the other end to jump out possible bad grounding connections (I would start with the VR case) and watch your meter for voltage changes. This should isolate the problem if it is a grounding issue. This is all done with the engine running, so SAFETY FIRST!

The 30+ volt reading is the result of using your digital meter. What you're reading is electrical noise. Your analog meter will tell a different story.
Here is Farmall Bob's trouble shooting chart. There is a different one for cutout equipped generators.
