2003 7.3 Powerstroke - Electrical Problem?

[orin]

Please help!

I was driving along just fine when all the dash gauges stopped working and no throttle. Sounds like a simple fuse problem but I can't find a bad one.

The engine starts fine each time, and idles great but no gauges, no throttle.

Is there another fusebox other than the one under the steering wheel?

I am missing something obvious, I think.

Thanks,

Orin

you have two problems. first is an open fuse, i cant remember which one....

What caused this is the wires for the OD button. they come out of the shift lever under the trim for the steering column. if the wires get frayed, they will then short to the steering column and cause your EXACT issue. i would put good money on it that this is your problem. if they are not frayed very much, you can tape it all up. if they are really frayed, that shift lever will need to be replaced........Marc

Thanks for the response, mschn99. I exposed the OD wires and checked everything around the steering column--- everything looks in great shape, no frays, bad insulation or the like. I can't imagine what fuse would protect the gauges other than ones labeled "instrument cluster" (there are 2 10amp ones)but I will pull out everything tomorrow and check each one. I am still stumped on the cause of this. Any other ideas?

i will all but garantee that there is an exposed wire on that shift lever wiring. I have seen this a bunch of times, and yes, it does take the instrement operation as well........you may need to look very close to find the short, but this is where the problem should be.....

and yes, there should be a fuse panel under the hood too........but i the fuse that is blown should be behind that knee panel if i remember right....

Turns out it was a 10 Amp fuse labeled "Ignition switch Run/Start feed" (#45).

I hadn't checked that one because the start sequence was fine. Anyway, still don't know what triggered it. . .all wiring is fine after lots of checking.

Thanks for the input!

Now.. . .what do I do about the fact that I disabled the door chime (working under there with it open was driving me crazy) by latching it without engaging the receiver bar on the rear doors(supercab) . I think the latch went too far and is locked by a notch on the cam?

Instrument cluster not working all fuses ok, truck runs fine turn lights on and instrument cluster lights up still. How do I check instrument cluster which pins provide power to gauges? Any help would be appreciated.
