Car Quits When Headlights Turned On
My '66 4-4-2 starts right up, even after sitting for weeks, but the first time that the headlights are turned on, it quits. It won't start again immediately, acts like a totally dead battery, but 15 seconds later, fires like nothing ever happened. You can then on-off the headlights without issue. Battery, battery terminals, cables, alternator, starter all good. Could a bad voltage regulator be the culprit? Or?

13.1 is very weak. Thats 0.5 VDC off the surface charge on the battery.
14.0-14.2 is normal.
Grounds Grounds Grounds!!! Find 'em, clean 'em, spary 'em with battery protenant.
Do you know how to test an external VR? Don't just replace it.
Could be the diode bridge in the alternator failing.
Load test the alternator and the battery (if you're suspicious of the battery).
Oh did I mention verify all grounds?
