Somehow, he did NOT replace the ALT fuse....he said it opened, he jumped the fuse connectors with a screwdriver, to ascertain the fuse was the problem, REINSTALLED the same fuse and everything then worked. He implied the fuse was "weak" or could fail and recommended replacement. Im not familiar with the operation of this type of fuse, so I wonder what I should do....take it to a dealer or what?
WHAT?!?!?!? If he bypassed the fuse, he has taken away the electrical protection for your vehicle. This is BAD. I doubt he removed this fuse, as it requires removing and disassembling the fuse box to remove and replace. Fuses do not get 'weak'. They are either open, or closed, there is no in between. At this point, you need to have the car taken to a competent technician, such as the dealer, or an independent shop VERY familiar with Toyota vehicles. The fuse needs to be replaced, and if there are any warning lights on the dash, such as ABS, or check engine light, you need to have those systems inspected with a scan tool. I would also speak to the general manager at walmart about this, as, unless someone else jump started it, or tried changing the battery, they caused this by installing the battery incorrectly and they should pay your repairs.
