Hello all. I'm not really the electronics type, but a recent motorcycle wiring project has forced me to familiarize myself with diodes & resistors & such. What I've got now, is a "universal" fuel gauge working off the signal from the factory fuel level sender, which of course is an oddball range (143-12 ohms F-E) that doesn't quite match. So to make it work I wired an 8 ohm resistor in parallel to bring it close to the 20-150 ohms my fuel gauge reads.
So now the gauge works, but it's backwards (empty is full & vice versa). The needle also bounces around alot as fuel in the tank sloshes back & forth. The factory gauge must have had some sort of electronic "damper" to quell that, it always responded very slowly to changes (like just after filling up), but also gave a steady reading.
So my questions are, what could I use to damp the signal from the sender so the needle doesn't bounce? Maybe a capacitor of some sort? And is there any way to also "invert" the signal so the gauge reads the right way?
