If you are worried about a car fire there are many things that you can do in addition to a battery master switch. Make absolutly sure there are NO fuel leaks or odors anywhere in the car. Inspect and clean all fuses, connectors, and relays. Install a Fanzilla or equivelent because the fan fail relay or the fan bypass is dangerous. Check the routing of all wiring so that is securely fastened and is not near anything hot or moving. Keep a fire extinguisher in the car (not in the trunk but where you can reach it quickly). If you have the Ducy alternater upgrade to something better. Finally install a battery master switch. The one I installed is on a bracket that slides under the battery. It was picked up at a car show for about $14. It has a removeble key. I can also use it as a security device and when I go to car shows and leave the doors open the battery doesn't go dead. I only had to make up a short cable to connect it to the battery. I also ran a wire from the radio fuse to the battery directly so I keep my presets even with the battery off (keeps the time going too). In case of a fire especially, while you are driving, I doubt the value of a battery master switch. I would trust in a fire extinguisher first! On most modern cars, at least the ones with fuel injection, in the majority of cases fires start out as fuel leaks. When you have a leak on a car with fuel injection a tiny leak isn't always visible as the fuel atomizes as it escapes. If it ignites now you have a tiny blowtorch melting anything nearby and eventually setting the entire car on fire. This is one of the reasons you are cautioned not to reuse the little copper gaskets that are used throughout the fuel system. On the Delorean, even though it is fuel injected, many of the fires appear to be electrical in origion. I have personally seen a fan fail bypass jumper melt in a member's car and if we didn't catch it, it wouldn't be a stretch to imagine the car burning! A master switch can't prevent this from happening and shuting off the battery isn't going to save the car once it starts burning. Preventive maintainence is the only sure way to prevent car fires.
