20050201FireELECTRICAL SYSTEM:WIRING
FIRE INVOLVING 2004 KENWORTH T-300 TRACTOR. FIRE OCCURRED ON 01/15/05. YOUR RECALL NUMBER 04V580000 OF DEC 09, 2004 SHOULD APPLY TO THIS VEHICLE, BUT KENWORTH SAID THIS TRUCK DOES NOT BECAUSE THE VIN IS NOT ON THEIR LIST OF RECALLS. THIS FIRE STARTED AT THE FIREWALL WHERE THE RECALLED HARNESS P92-1993 WAS LOCATED, AND THE CIRCUMSTANCES OF THE FIRE I BELIEVE MATCH THOSE WHICH GENERATED THE RECALL. PLEASE INVESTIGATE AS T-300 TRACTORS NOT ON THE KENWORHT RECALL LIST PROBABLY HAVE THE SAME PROBLEM. *AK
