Hi
I need help from someone in this forum with what I am sure is a very simple problem. I have a boat which has a separate oil tank with sensor which is on when the the tank is full and off when the tank is almost empty. I would like to install a warning lamp which lights when the tank is almost empty. Obviously a simple circuit would not work as the lamp would light when the tank is full and go out when the tank is empty. From my research I believe I need to include a relay to reverse the signal. Can anyone indicate what relay would be required and provide a simple circuit diagram?
This is a 12V DC circuit.
