Faulty battery, bad alternator, or both (photos)

Del,
I took your advice and tested for voltage drop (I saw you posted instructions in another thread).

With the car running at fast idle and nothing on, the voltage from NEG BAT post to VR flange is .01

I then turned the car off, left in RUN, and checked voltage from the blue field wire to the POS BAT post. Result was .10

This is troubleing, because this "looks good." Yet your charge voltage is some high. I would try following. Run the car for awhile, let the battery sort of "get normalized." You likely have been running it up/ down with all the testing and so on.

With the thing run long enough to have the engine / battery warm and "normalized," lights off, etc, recheck your charging voltage in another week or so of driving. If it's still high, I'd try another regulator

The only other possibility I can think of is.........bad connection at the VR connector

In RARE cases the battery can cause this

and..........you might "double check" your meter accuracy
