All these figures are on the low side or bad.

The battery was still charging on the Tender, hope everyone didn’t overlook this, I’m assuming this matters?

Thank you!

I'm no expert but I don't think a tender will give you a full charge. Use an automatic full function charger that will automatically drop to a trickle charge once the battery has a full charge.

Remove charger from battery. Let bat sit for 30 minutes and recheck voltages. I don't think your generator is working at all.

Any battery test should be made w/o any charger/tender on the battery

I decided to take the Bird in for service, It‘s a very reputable, classic car garage, so comfort level is high. As some of you diagnosed, the new regulator indeed needed adjustment.
