I agree, discussion without differences isn't. If not for different opinions we all would still believe Ford owns Cummins.

I am running from memory the wires wire that triggered charge is in the ECM connector and it traced that way. However, lots of pins and its possible the guy at the connector read the pin wrong, or, possibly the relay is in the PCM and it is triggered by the ECM, or the harness was shorted.

Five years and lots of times tracing wires could produce erroneous memories. Either that or I am getting old.

 

ok im gonna sound like the dumbass here! my 07 is charging funny and the tranny is starting to feel funny so where would the grounds for the tcm be located? one more question while im here. i recently went to a bigger rim and tire 35-12.50-20 been on for about a month and now there is a phontom vibration had the itres rotated and balanced twice been on the alighnment rack twice and have checked over everything with the truck on the ground and jacked up and cant find anything!! its driving me absolutly crazy from 60 to 70. please help thanks!

 

You don't have a seperate TCM, its in the ECU. Check all your grounds for the battery, the connections to the batteries themselves, have your batteries tested.

The vibration could be the typical drive shaft angle problem if you have a 2 piece shaft, or, a bad u-joint.

 

not a two piece but was goin to the ujoints next. thanks!!!!

 

make sure all you lug nuts are there and tight , not x-threaded. had some tires that I bought online mounted by the local tire shop, and they ran all the nuts on with the impact, an x-threaded one.
Prior to that though on another vehicle, I experienced a phantom vibration at 70mph on the interstate. so I slowed down, and it went away, then I sped back up. Then the back of the truck droped, and I looked in the rearview mirror in time to see my right rear tire and wheel bounceing all the way across two north bound lanes the median, and all the way across both south bound lanes, and into the ditch. Fortunatly no one was close enough to even concern them. I can only conclude that the lug nuts were loose. Three of the five were sheered of, and asside from destroying the aluminum rim there was no other dammage.

Can you feel the vibration in the steering wheel, which might point to a front end problem like ball joints, or wheel berrings
If you cant feel it in the steering, then then universal joints. In my experience they will cause a vibration so you cant even see out of the rearview mirror. I have had them come appart with little or no warnning though.

Im no mechanic though, just 25 years of driving and wrenching on my own used vehicles.
