Re: Power Cord/Adapter Issues
Based on my observations, and in agreement with svHyLyte, I believe the cause is high resistance at the connection - due to a build up of a resistive layer on the blades. Considering the environment these parts operate in, it's hardly surprising.
Once you have some resistance and parts start getting hot, it is a rapid vicious circle as the heat leads to rapid build up of a layer of corrosion.
I hadn't thought of adding dielectric grease, but will do
