Smart Diode cut out

[Bob Culver]

Thanks all, esp Simon, although I always maintain eelctronics are not in the spirit of Sevens (despite having some quite lofty albeit long forgotten qualifications!)
A mechanical cutout draws current which is wasteful. But as pointed out a normal diode absorbs voltage which is equallyo undesirable or worse. I suppose the unit will survive the enormous ignition hash present in many Sevens.
