I guess that the fuse is part of an assembly that screws into the body of the cutout. I don't have any of the parts (fuse, spring & holder that screws into the cutout cover. Can anyone provide the dimensions of the holder and the rating and length of the fuse? Also, how it is wired. There is a wire that comes out of the generator underneath where the cutout mounts. Does that connect to the terminal at the underside of the cutout?

Yes but do diagnostics first rather than buying parts that were mentioned only as a possibility as something to check. Not to make myself sound like an old timer (even though I am) but perhaps a little experienced advice might help give you a bit more confidence. I got my first car at 14 and did all the work on it myself without help, guidance or even a manual (other than an old beat up Motor's manual that was a decade too new) and, of course, there was no Internet either. Just think things through and that's how you learn, then ask for help when you're stuck. People here are happy to teach so I'm not saying don't ask but rather to also try to apply your abilities, which you may not even know you have, first!

Oh yeah, I updated my post to include his email address instead. It wasn't super quick, but very nice workmanship.

Hah! If you’re interested I’d pay for that work in beer and bad jokes! I am seriously considering finding a place that will just get it done but that’s getting pretty hard to come by unless you want to pay 100k for a full concourse restoration and be on a waitlist for however long for the privilege!! If I had the space, money, time, and skill I suppose I’d just live alone with my perfect Packards no one ever sees though.

With limited knowledge I am just taking and following suggestions right now…I don’t have the experience …starter seemed like a good place to start seeing that I don’t have a battery drain with the car off..

The URL posted is invalid and as far a I can see is that they do not have a Web site. Instead, as more and more places are going, they have a Facebook page.

What you DON'T want to do is to start blindly throwing parts at it in guesses. Continue with the diagnosis to find exactly what's wrong first, then fix or replace as needed. Even if the solenoid turns out to be bad, it would not cause the ammeter to misread.

As of a few years ago NAPA had them.

Does anyone know of a source for the fuse that screws into the regulator/cutout for a 1929 640?

If I start with a fully charged battery about 6.3 and then start the car and run it at idle for about 15 minutes..the battery will drain down to around 6 and unable to start the car again..the battery seems to be draining when it’s running…it was suggested that i may have a bad solenoid at starter…it was stated that I should not be getting voltage at starter while the key is off…I am getting full battery voltage where battery cable is nutted to starter..but I thought power at the starter from battery is normal but I really have no idea…the battery is new…
