I ran the test by grounding the field coil temporarily. The "genny" is hot! The meter pegged. So, cursing the voltage regulator, quietly.
Another factor is: I did put in a 6v Optima. As the voltage regulator is mechanical, I thought the Optima would not be an issue. Was I right??
Cleaning the points tomorrow...what saint should I address in my prayers?? A powerful heathen saint would suit just as well....

I have had this same question. Since it does not function as a volt meter, I just call it an ammeter. Close enough!!

Thank you James. I am delighted we are on the same page! I bought it 3 years ago so I would be reluctant to press you for any type of warranty. Thank you for maintaining quality in parts for our beloved treasures. I will run the tests to determine the problem and go from there.
Again, thank you, James!

Great response! Yes, I think the charging system is dead!! It never shows a charge. I will run the tests.
Question: How do I determine which terminal is the field?
I just bought an amp clamp but don't think it measures DC current. My old one did. I better find it!
I bought my last regulator from Kanter. Any other sources?? I have never trusted it. No gault of theirs but want to be sure to get one not made in China.

What is a the best way to test the current the generator is putting out? The Packard service manual mentions all this equipment which of course none of us have. Is it as simple as putting a multimeter on the battery with engine running and testing the current? I ask because when I drive the car during the day, normally the needle is in the center. When I put on the turn signals the needle will deflect a little to the left and then go back to center. But when I put on the parking lights the needle goes to the left of center and stays there. Eventually, it will come back to the center. It looks like the regulator is lazy. When I cut on the headlights the ammeter needle pegs to the left and stays there regardless of engine speed until I cut the headlights off. Regulator is about three years old and less than 1,000 miles.

I see you have the Egyptian hood ornament..congrats!!

Though blue, you are wise!!

When I remove my bezel, I tape the wood grain and use a rubber jar lid opener to rotate the bezel. What techniques are others using?

That is great news!
