Garmin G3X flap indication calibration

paulzielinski

I'm New Here
RV-12iS. Flaps work normally. When trying to calibrate the EFIS, the voltage doesn't begin to indicate during extension until about halfway deployed and when it does, it's negative. When fully deployed, the voltage is only .7V, not the expected 5V. The flap needle moves on the EFIS, just no voltage and therefore no way to calibrate the zero position. We are using a volt meter and the flap servo is putting out expected voltage. Any help?
