Brake Lights Quit..Guages sweeping..

Hello...I am new here, and I hope that I am posting this in the right area. I have a 2002 F-350 7.3 Liter 4 Wheel drive. Here is my problem..
1. My brake lights quit working (I checked the bulbs), thought that maybe it was a fuse, but cannot find it in my owners manual.
2. About 2 weeks after the brake lights qiut working, the battery light came on and all of my guages started sweeping and then a few minutes later the truck would just die. Yes I was still driving with no brake lights..I would turn my running lights on when I would hit the brakes to alert people behind me. Just couldnt drive at night. Blinkers, head lights and running lights still worked. So after the truck died and I was on the side of the road, I turned my hazzards on and they were real weak, and eventually stopped working altogether. I couldnt roll my elec. windows down either. So my brother showed up and we was able to jump my truck off and I got about 10 miles down the road and the same thing happened again. We got back to our yard and checked the batteries, and found out that they were weak..So I went and bought 2 new batteries (had just bought 2 new batteries 8 months earlier). So the truck started up fine after installing the batteries..but the battery light is still on. I drove the truck home and havent driven it since 8-10-12 I am scared that I will be on the side of the road again. A few years ago there were some electrical issues with the truck and all I can remember is that it stemmed from the Windshield wipers. I had it put in a shop that time. Cost almost $2000 to get it out. That I do remember very well. Any info would be greatly appreciated.
Than you
Christal Hoagland

1) Go have the charging circuit checked out. It probably isn't working.

2) Brake lights - separate problem. Probably a bad brake switch or the wiring harness near the switch. Check the high-mount brake light and see if it works and let us know.

Welcome to FTE. Pull your alternator and have it tested, most auto parts stores can test it for you for free. I also feel on your brake light issue the brake switch is a good place to start. Be sure to update us and let us know what you find.
