Understand How to Use Dielectric Grease - DO NOT APPLY TO TERMINALS - VOIDS WARRANTY
Dielectric Grease is an insulator. The use of dielectric grease in electrical connections is to help insulate the wires and seals coming into a connection. DO NOT apply to the actual electrical terminals in the connector because it can interfere with the electrical signals passing through the connector.
