Hi all - your help if may please. I'm going to fit a battery isolator as a further security layer to the 300 soon and need a little extra cable to go from it back to the battery. My question is what is the amp rating of the cable that runs from battery to starter? I don't want to just chop the existing as I'm planning on hiding it (well, as much as you can 'hide' an isolator) - Cheers in advance for any help
