Fuel Gauge
I have been playing around with the fuel tank sender & a couple of little trim pots.
Even though the sender wire connects via the sender to a dash panel return wire, it works equally well connected via vehicle ground.
This is what I have found.
Empty needs 71 ohms & measures 35mV
Quarter needs 119 ohms & measures 48mV
Half needs 166 ohms & measures 58mV
Three quarters needs 227 ohms & measures 64mV
Full needs 283 ohms & measures 70 mV
Is this wonderful little LCD display able to drive this gauge somehow?
