Yes in under the hood the other fuse box check the bigger fuses there. Chances are one of the bigger ones is now dead. One at a time with a meter. Anway notes from the wise. Don't get the cables mixed up. There is diodes everywhere on autos now. You get them backwards and those diodes that should be blocking current will conduct till they evaporate. You could do some serious damage man. It's negative ground, look where the wires go before you connect them up.

You may need to get some help if you cannot find a dead fuse is the cause. If you now have a bad diode you kind of sort of have to know how to trouble shoot to find them and test them.

There is no polarity protection on Autos. There is also a fusible link somewhere near the battery on the main battery wire. It could be that to. It's blue.

Actually it's near or inside the fuse box apparently and that is what is blown. Confirm with a meter. The blue fusible link. It will show open with a meter. It's blown if that is the case.
