I'm new here and didn't know where to go or whom to ask, or what category to put this in (my apologies). I would appreciate some help in understanding though.
I have installed a new sending unit in my gas tank(new tank as well) and new gauge in my dash. The sending unit and gauge operate (to my understanding) as follows: 0-ohms is empty, and 90-ohms is full. I filled the tank gauge reads full. I ran out of gas with about 1/8-3/16 reading on the gauge. I pulled the sending unit out and measured the ohms of the sweep. It measures 39-125ohms (empty to full). So i figure the sending unit is bad out of the box. But if that is the case, why would the gauge not have registered closer to 1/2 -3/8 of tank of fuel? The gauge has key hot on one terminal. Sending unit connection, and ground connection. Does this mean the gauge is wired in parallel with the sending unit, and that is why it shows close to empty when the ohms is 40?
