The car won't start, there's no power to the whole car, it won't click or the headlights won't work or nothing at all. I replaced the positive wire form the battery because it was burned.

This link may help--be sure to test all under hood and under dash fuses with a test light or multimeter:

Look for a "mega fuse" where the alternator wire connects to the under hood fuse box.

Make certain that both ends of both cables are clean and tight.
Too many times I've seen side post batteries cause no-start complaints.

I don't think I have a under the hood fuse, the only one I've seen is under the dash.

The wires are fine, and the battery is fine and clean.
