Protecting Electrical Connections


BOT Machine
Whenever there is an electrical connection whether it is a plug or a light socket, it's best to check the condition of the connection periodically and keep them clean to prevent problems with the circuit. Corrosion causes resistance and in some cases breaks the connection if bad enough.
After you inspect the connection and it is clean, an application of dielectric grease to the connection will prevent further corrosion and water infiltration into that part.

This is what it is and can be had in most any automotive or marine store.
