My name is ***** ***** I will assist you with your question today.

I'm an independent contractor and I don't get paid until a rating has been made.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

When you replaced these items, did you program them back on the truck? If the programming isn;t set on the GEM, it will not send power to the 4x4 module. It will act as if the truck is a non*****vehicle. Rule that out first for it will save a lot of headache and wire chasing.

All was done, all I want to know is which wire is the hot feed so I can trace it back to the fuse block. Ok? Thank you
Ford Mechanic: Jeremy, Certified Diesel Technician/Electrician replied 1 year ago

Sure, I can provide that.

I sent the offer for the diagrams. There are 6 total for the ESOF system.

Hello, let me ask a few questions. The 4x4 control module controls the transfer case shift motor, im not sure what you mean you you say you replaced the GEN. You also replaced the 4x4 control module? Will the 4x4 lights come on when the key it turned to on and start and go off(prove out like the other warning lamps)? Do you hear the transfer case engage into 4x4 high or low? Do the indicator lamps indicate a 4x4 engagement?

nothing happens,no lite on dash ,no shift motor movement.nothing. the only power i have coming to the esof is for the lite in it.the relays for the vacuum pump are good and do actuate the vacuum pump all the fuses are good checked on each side with a test lite. i dont know what else to check. the rest of the options in the truck work perfectly.I was told its possibly the fuse box but i am tired of throwing parts at it.this is exactly what it did before i changed the shift control motor and the gem .I have made no real progress. i had it to a local ford dealer and they tried throwing parts to.and nothing helped..Thats why if i seem a bit discusted ,,its because i really am .thanks,Pat

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
