[attachment=8144]I just bought one of those battery isolaters that clamps to the negative battery post. The earth cable attaches to a post on the isolater. Screwing a plastic knob in or out isolates the battery. Simple and neat? However on connecting mine, I had a bit of a struggle tightening the clamp on the battery post and the thing just snapped in two. See the photos. As you can see, there is very little "metal" where it snapped. About 1.5 mm thick joining the teo halves. Mechanically useless. Electrically dangerous?? I shall not buy another.
