I just had the starter and alternator rebuilt in my 87 omc cobra w/gm 3.0L. I would like to replace the ends of the wires (some of the connectors have some rust on them). Should these be brass, stainless steel, copper, and can I get these at the auto parts store or are they different for marine applications? Also, if I need to replace any wires, are they copper and braided or solid. I have no clue, this is my first boat. Thanks alot!
