headlight switch or dome light?

I have been experience problems with my headlight switch lately in my 79 z/28. I would pull the knob out to turn on the headlights and only the parking lights would turn on. Other times the headlights would turn on. Also, most of the time, only half of my dash will light up including only one turn signal indicator (the right side, if that matters). I pulled the light switch out of the dash bezel and plugged it in again. The headlights were working fine... Then I realized my dome light wasn't working. I pulled the dome light cover to find that the protective cover on one of the two the wires was burnt off and the two wires were touching. I pulled them away from each other and the dome light came back on. Before I spend 25 dollars on a headlight switch, I want to toss out the idea that the wires touching in the dome light could cause the weird headlight switch issues. What kind of symptoms might I see from the two dome light wires touching? Also could a bad headlight switch cause your battery to drain?

The only thing I can see the dome light causing is a blown fuse. Also in my chevette I had the same problem with the headlights not wanting to come on....ended up being the dimmer switch.

your dome light is constant hot and switched ground.....so if the wires were touching a ground it could drain your battery.
