Hello,
I am working on a fuel gauge for my 77' CJ7 jeep. the gauge came from a B17 air craft bomber. I was told I need to create a circuit with a digital pot.
My fuel tank reads about 17Ω full and about 80Ω empty, the B17 gauge reads empty with no power/resistance and 128KΩ full. also with 12.44v DC , current is 140mA with no resistance (pegs out). can someone help with a basic circuit using A digital pot to make the fuel tank levels match the B17 gauge?
Thanks
Kendall
