I have many new voltage regulators that came with a collection of parts. Basic, standard looking black, rectangle, delco style regulators. They all have different numbers on the backs. On the inside the all look the same. How do I tell if for 6 or 12 volts? And perhaps what trucks they go with.

Numbers include.
8AA
3KD
1HD
9CB
2LB
7FA

Thanks.

I do not know how to determine 6v vs 12v
I think you have date codes, not part numbers?

Year Month Day (Maybe?)
I do not know how to determine decade.

8 A A could be:

8 = 38 48 58
A = January
A = 1st (Happy New Year?)

Maybe someone know better/correct interpretation?

The 6 volt Delco regulators that I have seen all have two screws in the covers , one in one corner and one in the opposite corner on the diagonal. The 12 volt regulators have a flange on each end at the base level. t
The cover screws are short, one on each end at the flange. This does not apply to aftermarket regulators.

Check the cutout relay closing voltage- - - -this can be done with a simple battery and a rheostat. The regulator doesn't even have to be mounted on a vehicle. PM or email me for a more detailed description.

Used to always switch to a solid state regulator on both 6v and 12v. No coils/contacts to mess with. They (used?) to make solid state kits to fit into the original housing for the purists. Think most solid state ones run about $20 on ebay. Before internal regulator alternators we used the 64-69 Chrysler one wire in--one wire out regulator on the street rods. Very small and dependable so a mounting place was easy to find.
