1978 Chevy El Camino V8 Two Wheel Drive Automatic

I Have A 78 Elcamino and when you turn on the headlights, heater, wipers and then the volts meter goes down into the red. If you Have everything off it charges fine anyone have any ideas. I Have put a new Battery and alternator.

Double check wiring

There's a D-hole on back of the alternator ground the tap and see if the voltage increases if so the voltage regulator is defective if not the alternator
