Hi,
I want to use the voltage on a truck as a switch. when the truck is switched off its voltage is 24V I want to use the zener not to activate the relay at that voltage. when the truck star the voltage go to 28V for safety I will use a 27V zener that must pull the relay in at that voltage. Can this work, any help would be appreciated.
