just got ficm back from ed@ficm repair installed showed 48v koeo 47v cranking got down to 35 wot couple clips are broke on harness ran zipties to hold believe its a ground issue since I dont even know where my ground is. im a driller not a mechanic but I know how to spin a wrench. electronics are just not my strong point. appreciatr any help.
Hmm 65 series Batts are they not 650 CCA? iirc this truck requires 725 or better. With that said I don't think that would effect the WOT runs. Might want to contact Ed and see if he has an explanation or any troubleshooting method.
anybody with a pic of the ground wire does it come from the harness or is itjust off the case
