Can anyone tell me if/how you can check a fuel gauge. have two different ones, both have 3 terminals. one has S on one terminal (guessing s is connected to sending unit) another terminal has I or 1 (thinking I is for ignition) and a gnd. terminal. The other has a B terminal guessing Battery and T terminal guessing tank and gnd. terminal. can the gage be checked without the sending either with voltage or continuity and are my assumptions on the markings correct. Next what kind of continuity readings should you get on the sending unit. My reading are all over the place and intermittent on the sending unit. I have these parts out on the bench for testing. Thank in advance
