Preparing A Pass-Through For An Occupant Compartment - Engine Compartment Ground Block

摘要

A special patch is adhered to the bare metal of a dash panel in covering relation to one or more pass-through holes and their margins before a truck cab is primed and painted. After painting, a cover of the patch is peeled off to expose an electrically conductive medium that remains adhered to the bare metal. A ground block is mounted on the dash panel with a stud passing through a pass-through hole. The electrically conductive medium establishes conductivity of the body of the ground block to the dash panel.
