I need some help with a circuit design, now this is my first attempt at making something to last not just a bit of fun and learning to be kind please.
Basically it gets 3 inputs from a truck which controls other features on the vehicle depending on the inputs. I am trying to make this compatible with 12V and 24V thats why i went for the zener diodes on the inputs.
There are 4 outputs, 2 control relays, one outputs power to the hazard lights and the other is basically a ignition cut for the radio.
I have some electronics knowledge but is not the best. All comments would be appreciated.
Thanks in advance.
