Bipolar fuel gauge

[OzCharger69]

So the other week my fuel gauge was showing that I was on empty when I knew I had half a tank. I have Dakota digital gauges and you calibrate the gauge at 1/3 2/3 and full tank. I checked all connections and the earths all were fine. I emptied the tank and started filling up to recalibrate but the sender sat at 80ohms whether the tank was full or empty. So I thought the sender was dead or the float was punctured or stuck.

Today while cruising the fuel gauge came back to life. I emptied the tank to confirm that it was working well across the range and it was.

Any idea what could have caused this?

I am looking at the Dakota Digital Dash and have been doing the research on the fuel gauge because I want to know how to set it up. There is a section in the installation manual about a specific way to ground the fuel gauge. Did you follow that? Also did you try changing to one of the pre programmed settings to see if changed any response?

I've had the Dakota gauges for 3 years and I calibrated the fuel gauge 3 years ago and never missed a beat. The issue I have is from the sender.


Basically you pair the gauges to the Dakota app on your phone. Start the calibration with an empty tank, fill the tank a third at a time while telling the app when it is 1/3 then 2/3 and then full. It is extremely accurate.
