79 blazer and no lights
I have been playing with a 79 Blazer. I noticed I had a burned out headlight, so I replaced that, before I put the new on in, I hooked it up to test it. It didn't come on, then I noticed that I had no headlights. I looked, no taillights either. i turned my hazards on, and I had turn signals, front and rear. I checked the fuses, and I ended up putting a new headlight switch in. Unfortunately, this did not fix the problem. Where should I look next? The last tinkering I did was to put a new starter in. When I did that, i happened to notice a wire on the harness near the starter that was cut. I doubt its related, but just thought i'd throw it out there.
Thanks, Chris

Check the power to the switch first. If none of the lights are working I would bet your not getting current there since most switches redistribute a single voltage source to the different lighting circuits. Your hazards run independently of the lighting switch.

The main power feed comes up from the starter post through a metal tube next to the exhaust manifold, and then to the junction on the firewall (its just to the passenger side of the brake booster). In most cases it will have a 14 gauge fusible link connected to the 10 gauge wire that runs to the starter. All the other power feeds come off this point. The wire running to the passenger side is for the HVAC blower; the wires running to the right are for the fuse box and any auxiliary power you have (dual battery, camper lights, etc.).

If the dash lights come on, but headlights don't work, the next point to check is the dimmer switch on the floor.

Are you getting voltage to the + side of the switch?

I have the wire that runs to the starter hooked back up, and still nothing. Anything else I can check for?
