[bradleyrife]

Need some help here.....I have an 02 f250 7.3 P.S......for a while it has been blowing fuses when I would put it in reverse....the fuse for the auto lights,gages,and fuel pedal....so it did it again today but all the fuses are still good....it still starts and idles fine but not Fuel pedal.....does anyone have any ideas where we can start to look to figure this out.....Any ideas are welcome......Thanks.....BTW today it done it in drive not reverse

But the lights will work if you turn the switch, just not on auto

It sounds to me like there could be a short in the wiring that is only triped when the shifter is moved to reverse. Check your wiring around the shifter and look at any wiring down by the trans where the cable connects. May not find anything but it is somewhere to start.

Bump for the OP.

My 03 6.0 was doing something similar to this just recently while plowing snow. I think the 7.3's have the issues your describing. Mine would blow a fuse cant remember #41 or #45 and dash gauges didnt work and batteries would not charge. Turned out to be the wire to the tow/haul button on the end of the shifter lever was shorting out on the stearing column. Worn thru becouse of the constant forward/reverse shifting when plowing snow. Take the plastic shroud apart on the stearing column and inspect that wire. If its worn thru just wrap some electrical tape around it. Hope this helps.
