Fuel sender - correcting resistance?
Howlor - 29/10/05 at 09:45 PM

Hi,

My sender seems to be giving me 320ohms - 17ohms at full tank. My problem is that my gauge is designed for 100ohms. Is there any way I can correct this with some electronic jiggery pokery? The sender is supposed to be 100ohms so I don't know where it has gone wrong!

Any ideas most welcome.

Thanks.

Its hard to do it electrically but you could extend the float arm & play about with a meter & so that you dont use the full travel of the sender & only the first 100 ohm

I have a similiar problem with my fuel gauge,i am using a ford sender and a smiths gauge, i adjusted the sender for the full movement inside the tank but find when empty it reads correctly, but only reads half full when full.
I have thought of trying to make a circuit to take an input from the sender and extend the output to suit the gauge possibly using a digital potentiometer, but will probably end up just fitting a ford gauge to suit the sender , hopefully i might be able to fit the ford inards in the smiths casing .
