Blown Fuse/No Throttle/No Gauges
Really need some help here. I have a 2002 F-350 Single Wheel with the 7.3L. Several weeks ago on the way home the truck gauges died and throttle response stopped. After some fuse checking I found that the fuse which controls the dash/TPS at the pedal/etc. had blown. I believe this was number 45 on the diagram.
Having replaced the fuse I started looking for the culprit. I read some post on here about bad TPS at the pedal so my buddy and I hooked up this cool computer that graphs amperage draw to the TPS. We never saw a spike above 3amps after driving around for an hour.
I also saw some posts about chaffed wire harnesses near the left front shock tower. After a pretty good inspection, I can't see anywhere this has happened.
I also spoke to the heavy equipment manager at my Ford dealer about the TPS. According to him, he has never seen one go out on a 7.3L truck. Mine only has ~74,000 miles.
Do any of you have any idea what I should look at next?
Any help would be greatly appreciated!
