Okay I got a weird one here boys.

Well. Two days ago my right rear turn signal and brake light stopped working but the running light still works. When I would turn the signal on I would get a very small voltage drop but no light. Now tonight when I was about to leave the same thing is happening to ALL my lights. Interior, all exterior, and gauges. I turn the light switch on and the interior lights (guages) only come on for 2 - 5 seconds then ALL the lights start flashing randomly (not as a hazard light) and there is a huge voltage drop (below 10 volts) to the point where it idles very rough.

I have had experience with a crossed wire setting offf all lights to hazard flash but not this. I am thinking a ground somewhere but that wouldn't cause a voltage drop somewhere would it? I need help as I have a fishing trip and I will be driving at night.
