This suggestion was excellent it works the way i wanted it.
I got a problem though!
I was an idiot when figuring out what needs to vary and its not
the voltage. When i pulled out the guage again i found that there
is 3 wires feeding the guage.
Black = Ground
Red = 12v power
Yellow = current to ground through the fuel float
In the beginning i though the float varied the voltage
going to the guage. I was wrong
I can use the circuit you designed by connecting the yellow
to ground and varing the power to the guage. Although
i would be nice to design it around the original purpose.
Current! :roll:
What would i have to do to your circuit to change it to
adjust the current instead of voltage?
When i measure the current with a Pot i get
200mA with 10 ohms High
100mA with 80 ohms Low
When measuring the amps they were in pulses so this is the best i can get was the peak pulse at the resistant.
I am not sure what to do next i am running into
unexplored teritory for me. :?:
