I'm helping my buddy work on his 73 Nova with some electrical problems. The car sat for 2 years and he bought it up 2 weeks ago and started daily driving it. A week ago everything worked fine. Then the headlights went out, but he still had high beams. Then the high beams went out. The tail lights work, the brake lights work, the backup lights work, and the running lights work. The bulbs are new.
I pulled the connector that plugs into the headlight switch in the dash. It has 7 wires going to it.
Thick Red - Hot
2 brown wires (same terminal though) - tail lights/running lights??
Green wire - interior lights??
Orange wire - Hot w/ key on
black - ground
thick blue - ground
cream - ground
No voltage at the headlights (tested with a VOM)
I tested the black, thick blue, and cream colored wire and they are all zero ohms with the chassis all the time, so they are all grounded out. Does this sound right? Which wires (from the headlight switch) feed the headlights? And how is the fuse block involved with all this?
Any other suggestions on what to check, or what to do next?
