Hi, your question is too broad. Can you tell us which electrical system? What is the problem?

The problem is when I turn on the headlamps the inside lamps turn on too, but they do it in 6 volts, and the turn lamps turn on too, there ´s a loss of power somewhere, with the wiring map first I can check if everything is original and in its place.
Thank you.

Found this wiring diagram for headlamps. If you rotate the headlamp switch knob can you turn off the interior lites? If there is an interior lamp delay timer, that could be an issue? The better database where I have access, doesn't cover an 80 caprice.
