I have an autometer phantom guage (0-90ohm) o being empty 90 being full. I also have a RCI 10 gallon fuel cell (0-90ohm) 0 being empty 90 being full. I hooked the guage up properly and im getting reverse readings?? everything is functioning properly except the way the guage is reading. I cant figure out why the hell it is doing this, anyone have this problem? Ive checked the resistance and it is correct.
