FG-101 is a course in the construction and operation of the MGA fuel gauge. In the beginning it may be a little strange, because the gauge reading goes towards "E" as the resistance in the tank sender unit goes towards zero, increasing the signal current. You may browse the next few pages to become familiar with the construction of the gauge and a "simplified" explanation of its operation.
