When the environment is not controlled, electrical system reliability suffers. Many electrical components are located externally or under the hood, so they are constantly subject to thermal, mechanical and corrosive ambient conditions. The best option for combatting the weather, and keeping electrical connections corrosion-free is to seal them with heat shrink tubing.
