Defect

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.

Consequence

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.

Remedy
