Resistors in a fuel sender circuit
My question tonight is...
I have a fuel sender which is 18 ohms full and 268 ohms empty I need this to be 0 ohms full and 250ohms empty, to work with my acewell dash, is this
possible? I don't really want to buy that fuel sender wizard thing

No, you can't get it down to zero ohms with a simple resistor network. A 3700 Ohm resistor in parallel with the sensor will move it's
range to 17.9 -250 Ohms. However the sensor is close enough to the nominal 250 ohms that it should work perfectly well with the Acewell gauges
without any resistors.

Okay that's where I start getting confused. The gauge has 7 bars I think but the top bar won't work! The rest do and the bottom one
flashes when it is low low. I can power up the top bar by doing away with the sender. Any suggestions this is the second sender I bought

Unfotunatly not I tried for ages with different arrangements but they just don't work. You get one end right but not both.
You need the wizzard I reccomended to you in your previous post or a matching sensor.

Boll0cks, did you buy the wizard? I can't find a matching sensor anywhere I was searching for at least 2 hours the other night. I'll
either buy the wizard or hust have 6 bars on my gauge.
