Spi Fuel And Temp Guages Not Working
Posted 19 March 2020 - 09:35 PM
I have recently rebuilt my mini and the problem i have is that the fuel and temp guages are not working.
I have fitted a new temp sensor and it has a brand new engine wiring loom. I also connected both fuel sender wires together and the guage rose to the top. I then replaced the sender and have checked the resistance reading as i move the arm.
Both guages are still not working but they do have power to them as they move a tiny bit when i put the ignition on.
Does anybody know which wire to check from the ecu to the guages for the temp? And any suggestions for the fuel guage? I have also checked the earth to it.

Check page 455 of the PDF for the instruments and follow trace AC from the temperature gauge to page 460 to terminal 5 of the ECU. However, two failures must have something in common and that is the voltage stabiliser. I would check that first.

Start by checking for a good earth connection for the fuel gauge and the voltage stabiliser on the left taillight, almost behind the fuel tank. See if the solves it.
