alternator receiving 12 vdc from battery



I aggree with bigbill .When you say the alternator is recieving 12v from the battery, its actually the other way around. Your alternator is only putting out 12v to the batt and if you already replaced the VR, I would consider replacing the alternator. Check all connections to make sure theyre clean and no corrosion.
Good luck



Truth is, it goes both ways. There is no residual magnetism in an alternator like (proper) generators have, so you have to have voltage applied to the alternator to get it started.

Check the voltage from the Batt side of the regulator to the engine block. If you have the normal 13.8 to 14.5 there, you probably have some resistance in the wiring that is dropping the voltage by the time it reaches the battery. Cleaning up all the connections may cure it.
Also, most cars in that era had a grounding strap between the engine and body. If that is broken or missing, it could cause low voltage at the battery.
