I was driving home a few minutes ago and i was ona pretty cruddy road (bumpy, potholes) nothing too serious...when I hit a bump and lost all my electrical power... lights, engine, everything dead. All my fuses appear to be ok (although I only had my cell phone as a light) fortunately I was able to pullinto an AC Delco parts shop/repair shop... I need to knwo what possibly caused this so I can salvage my car ASAP...the only reason this is urgent is this happened in a pretty sketchy part of Waco, TX and I fear for my cars safety...as when I was leaving a small crowd was watching me from in front a seedy hourly rate motel... anyway, any pointers on the little info I have is very useful, also if any one here lives in waco, and can possibly help, PM me. Thanks.

first start off at the battery and work forward, I had a battery slide one time into the fenderwell and had the same effect, check for loose grounds , honestly sounds like something came loose or something grounded out , not the actually battery or alternator

so i tried jumping it, it started fine, took the cables off and it died. so alternator or battery?

This is important, WHERE were the jumper cables attached? If you connected "by the book", then that means that you connected positive to positive terminals BATTERY TO BATTERY, and the NEGATIVE terminal on the donor car battery was connected to the BODY or ENGINE of the recipient. If that's the case, then check the fusible link from the negative side of your battery going down to the starter solenoid.

If this fusible link gets disconnected or blows, it completely disconnects the COMPLETE electrical system of the car.

Bring a good battery and drive it home. You know that works then diagnosis it at a safer place.

Check your fusible links. I hit a bump once and it craked one of them near the bottom since they were so old.

Thanks, I checked all of those out. They were all fine. It was the voltage regulator.
