This relay?/eletrical thingy sits on top of the battery and is covered in white stuff which is going everywhere, also the connector also seems to be rotten, no signs of any acid leaks or anything - anyone got any clues? Should I replace the part, any idea what it does?
Personally I feel, given the location, an AGM battery which does not spill or leak (and also is a bit more tolerant of deep cycle events) is 'cheap' insurance on our cars...
