Fuel Gauge 47A
When the ignition switch is in the Drive position, 12 V is supplied to pin 2 of the temperature instrument from pin 22 of EDU 210. Fuel level sensor 46
is connected to the EDU which, after processing the information, sends a 1-9 V signal to pin 1 of the tank/temperature unit.
1 V = tank empty
9 V = tank full.
Temperature gauge 47C, fuel gauge 47A, instrument lighting lamps 18, and indicator lamp 47I are connected to ground via pin 5.
