Ford Repair: Dash and Tailight fuse, fuse, taking the time

Question
Hello James.  Thank you for taking the time to consider my problem.  I have been having a problem with my dash/taillight fuse.  The fuse is fine with the lights on...until I start the car.  Then it blows about 5 seconds after I start it.  Any ideas...?

Answer
Look for the chassis ground to have a problem.What you may also need to do is to take each of the taillight's out one at a time and visually inspect them for wiring problem.Did anything bring this problem on?Have you done anything like install a radio recently?
