Okay, I need help on this one - has anyone else experienced blowing a fuse all the time? Got a 2002 F250 xlt. Never had any problems with it, but now my instrument panel goes out and the ATM-10 fuse blows constantly. It seems to do it only after starting the truck and putting it in reverse?!? Though today it did it when I put it in drive. . .I know there's a short that I have to find, but was wondering if anyone else experienced this? And maybe where to start looking? Steering column maybe? HELP!
There is a short in the OD off button wiring in the shifter tube. Out F250 at work does this if you push the button. Your's probably has a bare spot in the hot wire going to the switch on the shifter. Our work truck has the bare spot on the wire going from the button to wherever it goes.
I don't think its the transmission shift lever harness if it's actually F2.41 blowing. The O/D cancel switch is on F2.45. However, F2.45 DOES help run the gauge cluster. Is it possible you're actually blowing this fuse?
Looking at the drawings for the 02 Superduty, I see that F2.41 goes to the cluster, but it's just a switch-through for the courtesy lamp circuit via a relay and does nothing that is evident from the schematic to operate the cluster itself.
If it is actually F2.41 blowing and the diagrams are correct, you've got an intermittent short in the courtesy lamp circuit.

It could be different on the F150. I know on the 2000 SD, if you push the OD button, it grounds out in the shifter and you lose the instrument panel gauges. I figured the F150 may be the same. I don't have any drawings in front of me to look at.
This is great feedback! Thank you - it is actually F2.41 that's blowing. The only thing I can attribute it to is when I change gears . . . and it's not every time I do it. . . Thank you again for all the feedback, I think it's a great start to eliminating the problem!
