Summary

14154 - service update. This bulletin provides a service procedure to relocate the separate 250 amp fuse into the pre-fuse assembly on top of the vehicle battery on certain vehicles equipped with a 220 amp generator (rpo kw5). These vehicles may, due to corrosion at the ends of the fuse, experience a resistance build-up that does not allow current to flow through the fuse, resulting in the generator not being able to charge the vehicle battery. The battery symbol may appear on the ip and a message in the driver information center will show “service battery charging system.” as the battery loses charge, the vehicle may stall or not be able to start when the battery goes below 11.3 volts. Depending on the state of charge of the battery when this occurs, the vehicle may have between 50-85 minutes before any potential stall condition.

Owners of these vehicles have filed 64 complaints in the electrical category.
