19ROADRUNNER
Member
OK, have a 69 roadrunner that I can not get the fuel gauge to read right. I have the 5v to the gauges (temp works fine and so does the amp meter). the fuel gauge, full , reads about half tank. and drops fast as fuel is used. the sender is the aftermarket style, out of tank works perfect, 70ohm full and 9ohm empty. did plug sender in, grounded gender (all out of tank) and gauge works fine. . I have put an ohms box on the fuel sender wire to test gauge, and gauge works perfect, 70ohm full and 9 empty, but with the sender in tank fuel gauge does not work. have checked the ground to gauge and is less than 5 ohms. did try another after market sender , same problem. I am at my wits end over this guage and looking for help please. this is the last thing on my to do list for my friend that I have built car for (he is recovering from cancer and knee surgery) and would like to have a car like he drove back in the day. thanks in advance for any help given.
