Fuel Gauge

Circuit consists of an electromagnetic gauge in instrument panel and a fuel tank sending unit incorporating a float, linkage, movable contact arm and rheostat. As float lowers with fuel level, contact arm moves over rheostat which decreases resistance to gauge circuit, allowing gauge pointer to move towards empty position. Gauge pointer may rest at any position with ignition in "OFF" or "START" and should move to correct fuel level with ignition in "ACC" or "ON" position.
