Is there any possible way to make a little circuit to adapt a fuelIf you could get inside the gauge cluster and see if there is a series
gauge to a sending unit with the wrong ohm range? Specifically, I want
to use a particular fuel guage that expects a 30-240 ohm range, and my
existing sending unit is 10-73. This is a factor of 3 across the range
(close enough), so I'm really wondering if I can somehow make it work.
I expect that classic car folks must run into this all the time when
they want to switch to modern gauges.
resistor in line with the meter movement, you might be able to change
the resistor value to get a wider range.
Other wise, a electronic impedance convertor would have to be built.
Sounds like a resister ladder problem for an EE major.
