I have a fuel level sender installed in my custom built car which supposedly should read ~50 Ohms when empty, and 2 Ohms when full. I've measured it 30 Ohms empty, but this could be because the arm/float is resting on the bottom at half-engagement.
I want to read this sender with a 0-5V input and from what I've gathered so far I need some kind of voltage divider for this to work. I have access to 5V and 12V.
My EE skills are nowhere what they used to be, can anyone help me out with this?
