Service bulletin SSM 50413

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Some 2021-2022 F-650/F-750 vehicles may exhibit various electrical concerns due to an open high current mega fuse array in the high current battery junction box (BJB). Service part LU5Z-14526-B has been released for service. It is no longer necessary to order the complete BJB to obtain these parts.
