Charging System Relay: Description and Operation
GENERATOR CARTRIDGE FUSE
A 140 ampere generator cartridge fuse is used on this model. The generator cartridge fuse is similar to other cartridge fuses found in the Power
Distribution Center (PDC). This fuse has a color-coded plastic housing and a clear plastic fuse conductor inspection cover like other cartridge fuses,
but has a higher current rating and is connected and secured with screws instead of being pushed onto male spade-type terminals. The generator
cartridge fuse cannot be repaired and, if faulty or damaged, it must be replaced.
The generator cartridge fuse is secured between the two B(+) terminal stud connection bus bars within the Power Distribution Center (PDC). This fuse
protects the vehicle electrical system from damage that could be caused by excessive charging system output and/or excessive electrical system current
levels resulting from a faulty generator or faulty charging system control circuits. If the current rating of the fuse is exceeded, the fuse conductor melts
to open the generator output circuit connection to the PDC. If a generator cartridge fuse fails, be certain to completely inspect and test the vehicle
charging system before replacing the fuse and returning the vehicle to service. Refer to Charging System for the charging system diagnostic
procedures. Refer to Wiring Diagrams for the location of complete PDC circuit diagrams.
