Hi Guys,
How does the fuel sender circuit work in the Saxo?
I'm going to a trackday on Friday but won't have a chance to replace the clocks (which I suspect are faulty - fuel gauge doesn't work but the fuel reserve light does), but ideally would like to see how much fuel I have left during the trip!
If I take a voltage reading between the smaller two cables on the pump/sender plug (live and earth), what voltage should I be seeing?
Does the sender/gauge assembly work by using a voltage to activate the circuit, and a variable resistor on the sender unit itself and the gauge just displays the resistance across that circuit?
Does anyone know what resistance values in ohms full and empty should read?
Thanks in advance for any help. My plan is to temporarily check fuel levels via a multimeter!
