I just bought a 2013 F-150 STX. When I got it noticed a flickering in the cargo light thought it was maybe corroded, did not think much about it. 2 weeks later the battery light keeps coming on. No out problems that I have noticed. It starts no problem and it is my daily driver so it's not sitting. It's at the dealer now and they can't figure out what's wrong, replaced the alternator tested it read that it was fine on the test drive the light came on again. So they are going to put another alternator in. Now I'm definitely no mechanic but this dose not make sense. I'm looking for any help I can get. Any ideas what it could be? I just bought it and I want to drive it.

 

what dealer is it at ? Ford ?

 

Yes, I bought it from a ford dealer and took it back to them

 

was wondering what brand Alt they were installing.. did they troubleshoot the cargo light flicker ?

 

I'm not sure. But I can definitely ask.

 

You may have a more complicated problem than this, but I recently got my
headliner re-done. The cab light at the top of the rear window(inside)which
comes on when you open the door...after the new headliner was put in that ligtht
had issues with flickering and just not coming on and I just took hold of it on
all four corners with the thumb and forefinger of both hands and wiggled it around
a bit which made the electrical ground better and have not had a problem since.
This is a 96 model F-150 so this may or may not have anything to do/w your
problem.

 

She has a 2013...

 

Anything is worth trying! I just got it it's my 1st truck and 1st ford, I'd love to be able to drive it

 

Let then replace the Alt again and see what happens.. I assume your not paying for this..

 

No I'm not thankfully. Thanks
