I totally agree with jya. Dieletric grease is the only way to go. A small tube goes a long way. The basic problem is that electrical connectors are often made of different metals/ plating. This is THE major cause of corrosion NOT salt water. Dis-similar metals in a salt enviro. make a mini battery and hence the corrosion. I learnt this lesson the hard way with a small fire caused by an ally. to copper connection that overheated due to high resistance. It is impossible to determine what metal/ plating is used by the manufacturers so play safe and use the grease. Good reminder jya, thanks. By the way, the best combination is nickel to nickel, but nobody is going to pay for that. Spent 15 years working for Chloride/ Exide so I did learn a few things.
