PACCAR issued a recall on the C500T600,T800, and W900 models

On certain vehicles, the main cab power and battery leads were attached incorrectly to the same side of the 135A circuit breaker when this circuit breaker was mounted in the optional firewall location rather than in the standard battery box location. This condition resulted on the main cab power circuit being unprotected. If a wiring short occurred anywhere along the cab power circuit, the available battery power could arc and cause a possible fire. Correction: Vehicles will be inspected and wiring corrected as required.
