Alternator on DD-3-53 does not charge at idle

I still think you're off on the date of introduction for internal
regulators. The one's I saw were based on ceramic substrate hybrids
such as this one from Delco:

I couldn't find a photo of the insides of a hybrid voltage regulator.
It's a ceramic substrate, with screened and fired resistors on the
substrate, conductive paths, and components attached with reflowed
solder. It's much like a modern SMD PCB, but using a ceramic
substrate instead of G10/FR4 board.

My 1963 Pontiac Catalina, and my 1966 Pontiac GTO both had firewall
mounted, mechanical regulators for their alternators. I had a 1968 GMC
Handivan that used the same regulator. My 1973 Chevy Stepvan (Union City
body on a school bus or motorhome chassis) was my first vehicle with an
internal regulator. I used to rebuild bad alternators, rather than
replace them. Brushes, bearings and diodes were easy to find, and
affordable to rebuild the existing alternator.

I had a 'Barney Fife' type tell me to shut off the GTO in the middle
of the road, because the lights were dim. I told him that I wouldn't be
able to restart the engine, if I did. I told him that I had just bought
a new regulator to repair it, and that I was only 15 feet from my driveway.

The stupid #$%^&* pulled his gun on me and screamed that he was going
to kill me, if I moved the car. My dad was home, and heard him. He
asked what was wrong. 'Barney' told him that he was going to shoot me
because I wouldn't shut off my car. Dad went back in for one of his guns
and told him to leave, or the sheriff would be called to arrest him,
since the Township police were not allowed to do more than write traffic
tickets. 'Barney' fled the scene when the neighbors started coming
outside, and heard him making more threats. He was a bad ass, with no
witnesses, but a real coward when the porch lights started coming on.

You needn't have worried... Deputy Fife only carries one round and he keeps that in his shirt pocket.

would have to know what type of alternator it is. many with an internal regulator need a positive voltage thru a resistor to charge at an idle. on many units, the resistor was the bulb in the idiot lite on the dash. units with gages had a resistor wired in. i dont recall the specs on the resistor. without that connection, there would be no charge at idle. the regulator would kick in at around 2000 rpm and charge. it would then charge fine at an idle , until the regulator cut out. with that load thru a bulb or resistor, the regulator doesnt need 2000 rpm to cut in.

Some alternators have a sing stud to connect to the battery. The
regulator has no external connections in that type. I have repaired
failed alternators on my vehicles since the early '70s.

Ford 2008 E250 does this when asked to power an inverter connected to the battery not Ford's computer system. The inverter has a whistler warning. If whistling on startup, the inverter is buttoned off then RPM raised to abt 1200 for 10 seconds then inverter on run back to cab n drive off before the damn thing changes its attitude. I assume this is the 'battery saver'

If the battery saver sees the load on the inverter is too high then on the second fail to restart with running ie not whistling inverter we give up n drive for 20minutes n stop to do over. The ectra charge usually runs inverter at a lesser load.

The saver is simple minded about its task. If 2 CTEK chargers are connected to inverter then a non whistling inverter is unlikely. One CTEK is probable but not 2. A CTEK is not asking for much voltage but... 2 buzzing at once is prob too much for the saver.
