Master Kill Swith

[Jon Davis]

Chaps,

I am working on a car that has the master kill switch on the negative side of the battery . . . in escence it puts a break in the earth. My own car has it on the positive side of the battery which I thought was the requirement in the blue book. I can't find any reference to it in the blue book and I can't really think of a good reason why having it on the negative other than my noddy theory that if the ngative cable came loose it could still earth on the car and allow the engine to keep running whereas if the live came loose and touched down on the chassis you would 'just' get a spectacular sparking light show.

Any comments.

I hate electricity, you can't see it leaking!

Cheers
