My sons girlfriends Mercedes ML 500 battery died. I was in the area but I didn’t have any tools. We called AAA and they provide a battery service. This poor guy had a rough time getting the shroud and negative terminal off. We find the negative terminal needs to be replaced and some wiring unrelated to the battery but hidden behind the battery starting to corrode. Is there a way to stop corrosion on these wires? She wants to keep the car for one more year until she graduates from law school. Thanks in advance.
