OK... as some of you know if you were at the pub I had a little eye opener by way of an electrical fire under the bonnet this evening. That said I am now looking at ways to isolate the battery. Of course I know that the simplest way would be to fit one of those nice isolator thingys with the big red handle! Similar to the one in Jai's motor. Is this the only way?
The reason I ask is this...
If I get another fire under the bonnet while I am out and about I must first stop the car... then evacuate all seven people - unstrapping at lkeast two and sometimes three babies from their seats. Then release the bonnet and activate the isolator. If I put the isolator in the vehicle then I diminish its effectiveness since there will be no protection for the length of cable running from the battery to the live side of the isolator.
With this in mind I wonder whether it would be possible to fit a large, normally closed, relay (160 amp maybe) close to the battery, and activate the coil by way of a small switch in the vehicle thereby cutting off the power from a point only inches from the battery itself. Feed for the coil would be via a seperate power source (a small supplimentary battery),
Viable?
