Ok so this is something that has me stumped, and I'm hoping that someone can give me some advice, or atleast point me in the right direction for a fix. Ok so this is what happened. I was on my way to pick up my daughter, it was early evening just as the sun set, it was raining, I went over a set of train tracks, not fast and there wasn't really much of a bump. As soon as my rear tires cleared the tracks my dash lights went out, when I got home, with further inspection I found that my tail lights, and brake lights weren't working either. I checked the fuses, and found one blown (parking lamps), I changed it, and as soon as I turned my lights on, the fuse blew again. I went through the entire wiring system from the tail lights to the fuse box, but found no snags, exposed wires, or anything out of the place. Can anyone give me any advice on were to look, or what to look for. I am totally stumped on this.

There isn’t a go to fix for something like this; it’s more of a search and rescue type of repair.
What I usually try; is to start disconnecting things, starting with the bulkhead connector at the firewall. If the fuse holds with it disconnected; then you know the problem is outside of the passenger compartment. If the fuse still blows you’re going under the dash looking for the short to ground. Which could be anything from a bared wire, to a bad switch; taking the circuit to ground, blowing the fuse.
