Thanks for any help with this, I am terrible with electric so please don't assume I know much. 1968 Charger RT parked for a few years. I changed the alternator and ballast resistor and the car starts and runs. No interior lights, headlights, brake lights, heater does blow the fan. Looking at Chilton wiring schematic trying to figure this out. The fusable link looks good and nothing melted in bulkhead, ammeter looks fine and the fuse block is powered in all circuits except the orange wire which I believe is only powered when headlight switch is on. But when I switch headlight on still nothing. I pulled the connector off the dimmer and pulled the connector off the headlight and couldn't get a test light or multimeter reading on any of the inputs. Not sure where the power is supposed to be coming from. Can anyone point me in the right direction? Thanks!
