Fuel Gauge

Circuit consists of an electromagnetic gauge in instrument panel and a fuel tank sending unit. Sending unit consists of a float attached to a contact arm and a rheostat. As float moves with fuel level, contact arm moves over rheostat which changes resistance to gauge circuit. Gauge pointer moves to reflect fuel level. Gauge pointer may set at any position when ignition is off, and should move to correct fuel level with ignition switch in "ACC" or "ON" position.
