This measurement determines the length of the sending unitвЂ™s float arm. If it does, it is working properly.ДЇirst measure tank depth from the top of the tank, near the sending unit, to the bottom. When you do this, the gauge should go to its lowest reading. If there is no ground pin, use a longer wire and jump the sending pin to the engine block. If the gauge does not reach its maximum reading, it is faulty and must be replaced.ДЄnother test is to jump a wire or a screwdriver across the sending pin to the ground pin on the back of the gauge. If this is the case then the gauge is good and you can proceed to the next step.

Once the wire is disconnected, the gauge should jump to its highest possible reading. With power running to the gauge, disconnect the sending wire it will be marked with an вЂњSвЂќ at the back of the gauge. If there are 12 volts at the gauge, either the sender, the gauge or its wiring is the culprit, so you need to proceed to the next step. Turn on the engineвЂ™s ignition and probe with a multimeter between the ground and the positive terminal on the back of the gauge it should be marked with a вЂњ+вЂќ or an вЂњI.вЂќ If there is no voltage then the fault is in the ignition circuit-and the gauge is probably good. First, check that the gauge is receiving 12 volts of power.

The first step is to determine whether the problem is with the gauge or the sending unit. Is your fuel gauge inaccurate? Is it no longer working at all? This is a common problem on older boats, but is easy to fix.
