Old car external voltage regulator woes

Maintenance/Repairs

On my 72 Cutlass over there < I bought a Delco regulator about 4 years ago that required some tweaking to get a good charging voltage from. I got it set and haven’t looked back. It is the 2 coil type. The only issue I have is if I try to have a short stop on a trip. The engine compartment heats up and then the field will not contact and set up charging. It stays that way until I stop, cool off and then restart.

I know the Wells VR715 is the best bet but does anyone know why this happens? Is there a little adjustment I’m missing that could help keep this hot start from not charging my battery?
