Hi
I think the battery isolator should be as close as possible to the battery. The type Colin suggests would be good. The problem is that a short can occur anywhere along the cable run and can be upstream from the isolator towards the battery. This would leave a remotely located isolator doing nothing. I would have thought the isolator should be connected to the positive in a neg earth car. Whilst not an "isolator" one of our modern cars has the fuses mounted in a pack directly onto the positive terminal to protect against shorts along the wiring harness.
