so ive got an 06 F150, 5.4l crew cab lariat. so to start, i had a programmer screw up my ECU, so when i got it re programmed at ford, everything works except for the ABS sensors. i recently had someone break into my truck and broke my stereo when they couldnt get it out. so i was driving home from work the other day and lost my whole instrument cluster, windows wouldnt roll up or down, wipers worked very slowly until not at all. shut off the truck and wouldnt restart. i jumped it and started it. ran fine. with the exception of the previous problems. i noticed when it got dark out that my my taillights and head lights were on very dimly with the switch off. also hearing a clicking sound coming from under the truck, at the back of the cab and front of the bed. the only thing electric thats back there is the fuel pump (i believe). im at a complete loss. any help greatly appreciated

 

Start with making sure your battery cables are clean and tight. From there follow the battery negative to the body and engine block and check those ends for tightness.

 

Charge the battery thoroughly, a jump start just gets you back on the road in an emergency. It won't bring a dead battery back up, unless you drive to Tennessee or something. Very common mistake!

 

I cleaned all the grounds. my battery charger pooped out. but i jumped it again and it ran so long as the cables where hooked up. same clicking coming from what i believe is the fuel pump

 

Hm, too bad about the old charger, but the battery still needs to be charged up. Don't try to use the alternator to bring up a dead battery.

 

Bad battery and bad alternator.
