Toyota Repair: 1994 Toyota Camry, fuse box, toyota camry

Question
My son changed out old battery in his toyota after changing it out nothing won,t come on in it now. I think he crossed up the neg-pos wires the first time causing something to blow.Could you help me out sir.

Answer
What usually happens is that the alternator fuse under the hood in the fuse box next to the battery blows, It's larger than the rest of the fuses and has a clear cover on it it's rated at between 80-100A, this fuse is bolted in and can not just be pulled out, the fuse box has to be taken apart to get to the bolts that hold it in.
