: Often grouped together; if multiple exterior lights fail simultaneously, it often indicates a loose ground or a blown main fuse in the firewall panel.
For detailed schematics, technicians often reference the KM815020 Pre-2001 Service Manual which covers the B-Cab power distribution boxes. Kenworth T80 or T800 fuse panel diagram needed
: Many electrical failures on this model are traced to broken or loose ground wires, which are typically white in Kenworth schematics.
The 1998 T800 electrical system uses terminal strips and spare circuits to allow for adding options. Specific relays identified in service manuals include:
: Additional relays, such as those for the ABS system or the A/C clutch, are often found behind the kick panel or lower dash panels, distinct from the main exterior fuse panel.
: If corrosion is found, use a dedicated quick-drying electrical cleaner spray after removing all fuses and relays.
: Power for the trailer ABS is traced from the fuse panel or a relay box near the battery. Maintenance & Troubleshooting Tips
: Usually the fifth relay from the bottom on the right side of the distribution block.
