This isn't mustang related, but wiring is wiring. I washed the underside of my car today. After letting it sit for awhile, I went to start it and nothing. No beeping, starter clicking, nothing. I jumped it off, let it sit for awhile and took it for a 10 min drive. Drove great.

When I got back, I turned the car off. I noticed the seatbelts didn't retract, and I put the key back in to try & recrank it, nothing.

Did I short something out? Would that cause my battery or alternator to fail?

Any help would be appreciated.

edit: Forget to add. the 2nd time I jumped it, it ran for 3-4 mins and died. Kinda leads me to think alternator. Had the battery test, tested good. Put it back in and it fired right up. I'd still like to know what's going on.
