I was thinking about security when out and about and thought about the "battery master switch" that is listed on all the cars that were exported overseas (AFAIK), this master switch is just a regular motorsport type switch that they connected between the main positive connection to the battery and the battery itself.
I was thinking of fitting something slightly more permanent, the same type of motorsport master switch but mounted into the rear portion of the battery cover with connections to the negative terminal since it's on that side.
As long as the leads are long enough to allow the cover to be lifted it would be easy to fit/remove the cover, and there is space behind the battery for the leads to drop into when the cover is fitted.
All you then need to do is to fit a fused connection between the master switch connections so that the alarm etc is still powered when the switch is disconnected.
If someone breaks in, or even gets the keys, when they try to start the car the ignition lights will come on but as soon as the starter draws current the fuse will blow and the car will be immobile. Obviously it would be best to keep the master switch separately from the normal keys, and you'd have to remember to put the master key back in before you attempt to start the car yourself!
Thoughts?
