For some time I have installed a remote battery shut off in my 12 volt cars. This allows me to simply flip a small toggle switch inside the car and all power is shut off without popping the hood and dealing with a green knob or knife blade switch. These excellent switches are sold by Ron Francis wiring. Until now a similar switch for 6 volt systems did not exist. AER, 866-228-0218 has designed such a switch for me and now has them available. This obviously won't impress the judges but it sure makes my trips to the store in my 54 easier and much more convenient.
