Hey, so I have a 2002 f150 that I am thinking has a bad ground. The battery has power but when you open the door no lights and the beep doesn’t start, when you put the key in and turn you get nothing. If you can think of anything lmk

 

How do you know the battery has power? Pull it, take it to a parts store, get it charged and load tested. Clean the terminals when putting it back in.

 

Classic symptom of a bad battery, bad battery connection or bad battery cable.
