On my way home from work I cross a set of railroad tracks. Yesterday when I crossed the tracks everything on my dash quit. In the lower right hand corner the security lock light came on. When I got home and shut my truck off it wouldn't start. I read online that I had to let the truck sit with the key on for 30 minutes then turn the truck off for 30 seconds. I tried that and it didn't work. I disconnected the battery and re-connected the cable and started it. I drove around the block, the same thing happened, the gauges all quit and the light came on. I hit a pot-hole and all of the lights came on and the brake warning bell chimed. Now it starts but the engine warning lights are still on. Can anyone help me?
