All "always on" powered items do not function, and Anti-Lock brake light came on. But no headlights, taillights, brake lights, power seats, radio loses time. Checked all fuses. Not power at fuse box to lights, brake/taillights, ctsy.

Hi,

Based on what you lost, it sounds like fusible link B has failed. A fusible link looks like a wire but is designed to function as a fuse. If too much current flows through it, it will fail and prevent power flow.

In this vehicle, fusible link B is located under the hood on the left side (driver's side) near the battery. See pic 1. It should be a rust color and connect into a red wire.

If there is no evidence of it being bad, check for continuity from one end to the other. Here is a link you may find helpful:

Let me know if this helps or if you have other questions.

Take care,

Joe
