[QUOTE="Decoy, post: 530281, member: 17310"] +1 Dead driver You want a zener diode over voltage protection, is the way to go and its very simple. You can also add over voltage protection by I would place a 9.1V zener diode parallel with a fuse on your power input, when the voltage hits 9.1v the diode will conduct shorting out the circuit and blowing your fuse. I would suggest this 9.1V 5W zener diode from Element 14 for sub $1, you can also try RS components, WES or Jaycar etc.. element14.com/on-semiconductor/1n5346brlg/zener-diode-9-1v-5w-axial-leaded/dp/2844766?st=zener%20diode%209.1v you can also add a reversed normal power diode rated for 2-5 amps incase you reverse the polarity. here is site with about and how to. learningaboutelectronics.com/Articles/Overvoltage-protection-circuit.php [/QUOTE]
