A firm I know manufactured a number of gas tank sending units with the incorrect resistance range. The range should be 20-225 ohms - instead, it's 10-125 ohms.
I thought some combination of a parallel resistor in combination with a series resistor might do it, but to achieve the high end, the series resistor would have to be >= 100 ohms, and in the low end, it would have to be <= 20. So, it's no realizable. Looks like I need an active circuit of some sort.
Any ideas for something cheap and easy?
