The hazard

On certain vehicles, the ground stud that retains the negative battery terminal eyelet to the engine block may be loose. A loose battery ground wire may produce high resistance to current flow. As a result, current may take an alternate path to ground through the radio suppression strap causing it to heat and potentially melt or ignite adjacent components. Correction: Dealers will replace the engine ground stud. The radio suppression strap and adjacent components will be inspected for damage, and if necessary, replaced.
