hello. we hope maybe someone can help with the problem we are having with this 96 mustang v6. originally it wouldnt start. battery replaced, everything was fine for a week or so and then the new battery died. assuming the alternator was not keeping the battery charged, alternator was replaced. Found out a lot later that the battery was defective and so battery was replaced again with another brand new one. Car will not crank. Starter has been checked, battery is brand new, alternator brand new. When key is turned, a noise comes from what looks like a junction box which is located behind the passenger side fender. The fender had to be removed to see this item. Can anyone say what the name of this is and what the noise could be. Battery cables, connections and wires have all been replaced. Cannot figure this out. Any help would be greatly appreciated. Thank you.
