I finally am getting around to fixing my fuel gauge, and I've got a question for the wise minds and maverick scholars out there: When I bought my mav, the guy i bought it from said "A wire would need soldered back on to the sending unit, because he yanked it off/broke it when he dropped the tank to clean it out". I was suspecting he meant the terminal on the outside of the sender, but when I got under there to fix it, it was fine. The sending unit wire was pulled and tied off to the frame. I reconnected the boot to the two pole terminal outside the tank, but still nothing. So, I suspect there is a wire or connection in the guts of the sender in the tank that he was talking about? Before I drop the tank, and as illogical as it sounds to have a connection needed soldered that lives in GALLONS OF GASOLINE , i thought i would ask if anyone else can decode his supposed fix to the issue. I traced the sending wire back about 3 feet, and there doesnt appear to be anything frayed or broken on that. I am wondering if he may have meant something on the gauge itself? Any thoughts out there on what this could be? I'm sick of feeding the Oil monster $8 a day so I can be SURE I don't end up thumbing my way to a gas station! Also, I hate things that are not working - take 'em out or fix 'em (big predicament I am in with all the dead, and always useless idiot lights right now). Thanks fellas!
I had a issue close to this. My flotter needed to be replaced it had fuel in it. Keeping it down. Hope tha helps.
Hook up an ohm meter between the center terminal and a ground. If the guts are good, you should see between 10 and 73 ohms. If it's either zero (grounded) or infinite (open), there's something broke inside the tank.
To check the wiring and gas gauge - pull the wire that goes onto the stud of the sending unit off and ground it right to the frame of the car. While you are under the car doing this, have a helper inside the car watching the gauge (key on for this). If all is well with the wiring and gauge it will rise up to the full mark rather quickly. If it goes to full you know there is nothing wrong with the wiring.
