[QUOTE="Thomas Rogers, post: 939112, member: 60724"] It's a form of "galvanic corrosion" caused by passing a current through two dissimilar metals. Essentially, the terminal and the connector take on the roles of an anode and a cathode, and if of dissimilar metals the ion jump between the two generates the corrosion. It cannot necessarily be avoided, but it can be reduced and slowed considerably. To remedy: Disconnect and clean the terminals and connectors with baking soda and cocoa cola mixture (try it, but be careful as you mix) using a green scrubber pad, insert a felt washer below the connectors to help reduce any gases you MIGHT be getting from a loose terminal seal, reconnect, then cover exposed post & connector with petroleum jelly or a spray especially made for the purpose of protecting against corrosion as keeping acids, salts and moisture away from the metals helps to reduce the corrosion.
