Hi,
I'm looking for a circuit which would trigger a 12V relay from a fuel level sensor so that when the fuel tank is full the relay is triggered.
I believe the fuel level sender reads 560 ohms empty and 55 ohms full. That means I would like to trigger the relay at or below 65 ohms but not higher.
This is for a '87 Vanagon and I want to disable a pump transferring fuel from my axillary tank to my main tank when my main tank is full.
Thanks for any help,
David
