robp823 Posted February 8, 2009 Share Posted February 8, 2009 Got an 06 that keeps popping the 5 amp mini fuse for the ipr,icp,maf etc etc.... Has alot of circuits on this fuse, just wandering if anyone has had trouble like this or knows any known wire chaffing spots only did a quick visual saturday.

Bruce Amacker Posted February 8, 2009 Share Posted February 8, 2009 I do remember an updated harness/rub spot out front near the grill, but I don't remember what circuits it shorted. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted February 9, 2009 Share Posted February 9, 2009 I ran into this with several trucks when the LCF first came out. We had delivered many in the beginning and three of our customers had problems. I wrote an article about the harness problem I discovered (LCF Wire Harness Chafing) which also became TSB 05-26-22.

robp823 Posted February 10, 2009 Author Share Posted February 10, 2009 well checked all those spots and found no chafes everytime i unplug the mass air flow the truck comes to life with my test lite in place of the fuse.Tried switching with a known good mass air flow and nothing. i need a gun and a bullet right about now just about went through the whole harness on this thing chasing down circuits and found nothing.

LARRY BRUDZYNSKI Posted February 11, 2009 Share Posted February 11, 2009 What kind of body was put on the truck? Could you have your wiring problem back there? I have seen in the past that some of the body builders aren't very careful with the chassis harnesses. Quote Link to comment Share on other sites More sharing options...
robp823 Posted February 12, 2009 Author Share Posted February 12, 2009 Its a box truck, attempted an overlay today but not sure if its gonna work. I talked to hotline and they said that there has been alot of problems with these harnesses and also that they are on national back order due to high demand. The worst part about this thing is that its intermitent so half way through testing the damm fuse doesnt blow.Ive basically been through the whole harness and cannot find anything.
