1992 mazda mx6 lx. I got back from spring break and it wouldn't start, wouldn't even turn over. none of the cabin lights would turn on dome light radio dashboard ect, but the headlights still turned on turn on. It seemed like a dead battery so i jumped it for 45 min, still nothing. Took the battery to auto zone and they charged and tested it said it was fine. Checked all the fuses under the steering wheel and under the hood. i'm left thinking there is a connection problem with the wiring, but i'm not sure where to look. Any suggestions?
