I'm having a weird issue with my innovate ethanol gauge. My original ethanol gauge was reading 1.2xx volts (yellow output wire) on 10% ethanol which is incorrect as it should've read .50v(setting: 0v = 0% and 5v = 100%). Innovate warrantied the gauge and sent me a replacement. The replacement gauge reads 9.8 - 10% ethanol on 93oct which seems correct but the output voltage wire(yellow) is producing .25v but shout be around .45-.50v. I'm going crazy trying to get the output voltage wire to output the correct voltage. Has anyone ran into this issue? Is it possible i got another bad gauge? Also, the ethanol content sensor wires into the gauge and the gauge outputs the ethanol percentage to voltage.

I'm going to try another source for power and ground to triple check....

In California, our 91 octane has 10% ethanol ever since MTBE was banned.
