ok here's the story plugged my boat trailer into my f250 blew my gauges out so searched for fuse all were good switched every fuse out just to make sure!!!! Just drove the truck anyway was not gonna stop a good day fishing lol!!! Got to the lake and my truck died out battery was shot got a new battery drove fine got it home just to find out my alternator went out and my battery was actually good still!!! My truck was dead again replaced alternator and everything was fine still no gauges though 3 days later starter went out changed it now all good but no gauges still I searched the harness for bad/corroded wires connectors etc etc etc nothing I switched all the fuses again and nothing I have no 4x4 no over drive no spedo tach gas temp mileage or trip no maitnace lights all I have is illumination and blinkers any suggestions?????

 

How about an English composition class at your local community college?

Can't make heads or tails out of what you're trying to report.

 

My gauges... they are not working at all!! Started with the trailer blowing them out I never got them to come back on but after that incident numerous electrical problems happened... such as the alternator the starter and battery.. even after replacing these parts I still have no gauges any idea where to look.. I have already checked every fuse!

 

Does the backlighting work, just not the gauges? Does the radio work?

Backlighting does work as well as the blinkers!!! The radio does work as well!!

 

Funny it started with the plug for the trailer and all signal lights seem to work. This is going to be one of those take it to a mechanic ones because tracking down electrical is a headache. I will be honest I haven't done much work on anything older than 1980 because of the computers they put in them. The Mechanics have a better test equipment than I do and it might track it down easier. You can take it to a dealer and they will diagnose it for you for a fee, that might be worth it to make it easier to find. Make sure you check all the fuses there are several, some inside the truck some under the hood and some blocks in the fuse panel you might not be able to tell just by looking.

 

The trailer bit was coincidental, nothing else. There's nothing in the trailer wiring that can cause a failure in the cluster, they're all on separate circuits.

We need to know the YEAR of the truck, the circuits have changed over the years. Without that, there are too many possibilities to try and cover.

Nonsense! This can be easily troubleshot via the forum if the OP provides proper observations and feedback and has a multimeter and the basic ability to use it.

 

It's a 2003 f250

 

Now I have already pulled every fuse out of the panel under the dash and replaced with what was called for!!! I have only had the truck a year and when replacing the fuses I noticed a lot of them were wrong size....cluster being one!!! they had a 30 amp in it and I wanna say it called for a 15 or 20 amp!!! I also checked voltage at each fuse I was right around 12.7 volts on each fuse in the panel.. I do not have a fuse panel under the hood I only have 5 little black relays. I have not pulled the cluster out to test voltage on each power pin in the harness or to even test the ground that was my next move!!! But I am getting frustrated so I figured ask the experts (you guys) everyone always has great insight to problems so why not ask!!!! Thanks in advance for the help!!!

 

 

Don't have that only 2 small black boxes one wth 3 relays and one with 2 relays !!!

 

What country is this truck in?
Which engine does it have?

 

Us and v10 gas

 

My 03 (5.4, U.S. market) is the same way. There's NO fuses under the hood, just the two relay blocks. All the fuses are under the steering wheel.

Yep, my bad. The pic shows what the early ones like mine use.
