I put my battery on wrong on my 1991 f150, fixed the fuseable link and radio doesnt work? every thing else is fine.

 

What exactly do you mean by wrong? Like pos to neg and visa versa? I did that once, had to replace a lot of wiring. If you've got an amp hooked up there should be an inline fuse from the battery, otherwise I'd check your radio fuse. Worst case scenario, you fried your radio.

 

You didn't read his post ??? He said FIXED the fuseable link... Runer check all your fuse's ...but if your radio was on at the time you made your boo boo like Bibo said...it may be fried.

 

Check for an inline fuse behind the radio. Usually w/in the first 6 inches of power wire.

 

If all the wiring and fuses check out and the radio still is not working, you may have blown the protection diode inside the radio. If you are feeling brave, you can check this diode with a multimeter on the diode setting (some meeters group this with continuity setting) and replace it. If you cant find a replacement diode, you can just bypass it with a jumper and hope you never get the polarity backwards again.

 

On a side note: Never try to take a **** & plug in a blow dryer at the same time! At least til you master the positive/ negative battery thing anyway.

 

 

My truck has two fuses for the radio. One in the fuse panel inside the cabin, and one in the power distribution box under the hood. Make sure you check both.

 

Yes, I read his post. I though a fusible link and in line fuse were 2 different things, still pretty sure they are, but the term may be interchangeable. Either way, I was thinking more of the in-line fuse in the power wire to the amp, if he's using one.

 

The fusible link(s) is/are kinda the mother of all inline fuses & under the hood.
Not to be confused w/ inline fuses that many times comes w/ a component As a secondary protector.
