This is Clay, I'm a certified master automobile technician with 30 years of automotive repair and diagnostic experience.

From your description most likely there are blown fusible links just off from the battery positive. The link below is the location of 3 fusible links at the battery.

Fusible Links B, C & G

Fusible links act the same as fuses. An electrical fusible link is a type of electrical fuse that is constructed simply with a short piece of wire that is smaller than the wire that is being protected. Fusible links are common in high-current applications. The wire in a fusible link is covered with a high-temperature fire-resistant insulation to reduce hazards when the wire melts. Fusible links are designed to melt and not catch fire where a regular wire would possibly catch fire.

The rust colored fusible link B protects the fuses in the fuse box for all of the lighting circuits a power accessory circuit for the door locks. Fusible links B & G protect circuits for the brake light switch and the ABS enable relay. These circuits should be checked with a test lamp to verify the circuits integrity.
