The problem
ON CERTAIN TRUCKS EQUIPPED WITH CUMMINS ISC OR PACCAR PX8 ENGINES, THE JUMPER WIRE BETWEEN THE GRID HEATER RELAY TO THE FUSE BLOCK HAS BEEN ROUTED IN SUCH A WAY THAT THE POTENTIAL EXISTS FOR IT TO RUB AGAINST THE RADIATOR SUPPORT.
Risk
THE SUSPECT WIRE IS DOWN STREAM OF THE FUSE; THIS CHAFF POINT COULD CAUSE THE 250 AMP CHARGE WIRE TO ARC, POTENTIALLY CAUSING A FIRE.
What owners should do
DEALERS WILL INSPECT THE ROUTING OF THE JUMPER WIRE. IF THE WIRE IS NOT ROUTED CORRECTLY, IT WILL BE INSPECTED FOR RUBBING OR CHAFFING AND REPLACED IF NECESSARY FREE OF CHARGE. THE RECALL BEGAN ON JUNE 22, 2007. OWNERS MAY CONTACT KENWORTH AT 425-828-5440.
