Mike:

Good job of getting into this. Thank you for the excellent operative report. You can substitute a compass for the small wrench. I'm not convinced that you have a double alternator failure, that would be quite rare. Do you have a run/standby switch in your model?

It is normal to have a one volt drop across the VR. Keep at it. You're getting close. At this point in time it would be a good idea to charge the battery. We don't want the alternators to go full tilt when they come back on line. I neglected to mention that I took the Alternator System page of the electrical manual and had it blown up to 20" x 30". This makes the job much easier to trace out all the wiring.
