Do you have an internal or external regulator?

Looks like it is internal
double check the health of both the alternator and batteries. small chance one could be bad new.
Also check your charging fusible link. They can look ok and still pass a continuity test but not flow enough current. Look for a voltage drop across it when charging.

I put the battery in a few days ago, and I’m getting over 14 volts from the alternator at idle.
I’ll check the fusible link tonight
you need to load test a battery to test it

Fusible link seems fine, couldn’t get a voltage drop across it

Mine just started doing this also. I haven't dug into it yet but I believe it is the charge relay, which also has the function of turning on the lights as a bulb check before starting.

On a 70 series it may be the one called Bulb Check Relay. Someday I plan to diagnose but haven't yet.
I should add that mine are flickering and charging as normal which is why I suspect a relay.
But for solid on, I'd be verifying the alternator, plugs, fusible links, and all grounds are solid.

Well now you have me thinking about this. I retract my earlier post - definitely not the bulb check relay. Per the ewd that is only connected to the brake light.
So it is definitely related to the charging system or its wiring.
