A friend of mine is having problems with her car. it's a 1992 ford taurus.
The symptoms according to her: Nothing electrical works. no lights, no radio, no clock, and no starter.
I suggested a dead battery or alternator, she said both have been tested at Advanced and they are alright. Although someone at advanced told her not to always trust those tests.
She's tried jumping it, and nothing happens.
Maybe a bad ground coming off the battery?
