No Instruments, No Throttle

I need some help with this one

2003 f350 king cab, Dually, 7.3 liter diesel, 2wd

Number 45 fuse has blown a few times in the past causing no instruments and no throttle response. I replaced the fuse and it would work for a while.

When the truck had the same symptoms yesterday, I checked the fuse and it is good.

I have repaired the bare wire in the shift lever and reinstalled but same problem. I ordered a new shift lever.

I have removed and checked every fuse twice

I have read out every fuse with a meter, every fuse is good.

There is 12 volts on both sides of fuse 45 when the ignition is on

I have read many forums on this issue, but hey are all solved with the fuse being bad. This seems unique since all the fuses are good.

Is there anything else I can check while I wait for the new shift lever?

Thanks to all

if your truck is an automatic, remove the steering column and check the wires going to your over drive button. the wires get a place wore in them and ground out blowing your fuse. take your time looking for the spot took me awhile to find mine. use some electrical tape to cover the spot.

Thank you,

I pulled it and there is A wire that has been chafed. I repaired it and reinstalled, same problem. I ordered a new one, it will be here in a couple days. Is the anything else I can check while I wait. I have read that bad grounds can cause similar problems. Any idea where the grounds are at?

Thanks again

I will be looking for shorts this morning. I am still waiting on the new shift lever, but I double checked the one that I have and it reads out fine, so I do not think that is the problem. I am thinking about replacing the fuse box. Where can I get a schematic for this truck?

I changed the shift lever today, still have the same problem. No throttle no dash instruments. Does anyone know what else runs from fuse 45?

Thanks

i second that. my truck had the same issue and the problem was fuse 19 under the dash. when 19 goes you won't have throttle, overdrive or any gauges

In an '03 (and some '01s and all '02s) #45 does what #19 did in the older trucks. It's either one or the other, not both
