The problems have been fixed!

-I replaced the oil pressure switch.

-I did a diode test on the regulator - which interestingly had not been suggested in this thread - and the test results indicated that one of the diodes was blown, or was otherwise not working. Discussed the test with Electrosport, and they asked me to send in the unit for further testing. 

-Rather than wait for the Electrosport people, I bought a new Ducati Energia (OEM) regulator from MG Cycle and installed it yesterday.

-Fired up the bike a few hours ago.  Oil and battery lamp come on with key on. At idle the battery terminal test at 14vdc +/-, and increase when revved. Went for a 100 mile ride: South St. Vrain Cyn - Peak to Peak Highway - Coal Creek Cyn - Home.  Had a blast! Foliage, not much traffic, no battery light at 3-4000rpm, and the bike just roared along.

Thanks to everybody on this thread who offered thoughtful troubleshooting suggestions. I really appreciate all of the time and effort many of you have put in trying to help me out.

Cheers, Sam

In defense of all members of this forum , we were answering all questions concerning this charging system with the understanding your bike was not charging correctly before and after the installation of the new parts.  

 This test was/is an Electrosport test to test the R/R to see if it might be bad. I read all the flow chart and troubleshooting guide. The guide shows a 3 phase stator in the diagram and this charging system used on this bike is a single phase stator. Two yellow wires will be a single phase where as three yellow wires  will be a three phase charging system.

No , Sam I didn't miss that. We were giving troubleshooting advice w/the understanding you had installed good known parts. This is not a pissing contest. We are happy you got your bike up and running .

Sounds like a happy ending after all.  Great news.

Don't want to put a damper on anything, but what does it go up to at high revs?

If it gets much over 14.8 or so, you'll be back to cooking the battery, as far as I know.
