Abstract: A protective cover for substantially completely enclosing a ground junction connector to inhibit contamination of the electrical contact surfaces of the ground junction connector when it is in use. The cover comprises a housing that fits over the ground junction connector and an end cap which matingly engages the housing to trap the ground junction connector in an enclosed position within the housing. The housing has a lower surface with a bolt hole formed therein and an upper surface with a larger access hole formed therein. The holes are in coaxial alignment with one another so that a bolt may be inserted through the access hole, into engagement with an eyelet attached to the ground junction connector, and out through the bolt hole to connect with the ground point. The end cap has a wire hole through which a wire harness attached to the ground junction connector extends. A lid is attached to the housing by a hinge and seals the access hole when in a closed position.
