[C320-list] Fuel Assembly Question

[Chris Burti]

Ok...a kiss reply

The sender is a rheostat or adjustable resistor and the gauge is an
ohmmeter measuring the reistance in the circuit as reflected by the
height of the float.

Testing Fuel Gauges Proceedure follows:

1. Disconnect Pink Sender Wire from Gauge, and turn power ON. The Fuel
Gauge should read ZERO Scale (< Empty)
2. Short the Gauge Sender Terminal to Ground. The Gauge should read FULL Scale
(> Full).
3. Measure resistance of Pink Sender Wire to Ground.
American Floats: 240 Ohms (Empty), 103 Ohms (½ Full), & 33 Ohms (Full)
European Floats: 10 Ohms (Empty), 95 Ohms (Half), & 180 Ohms (Full)
Automotive & other Float Switches may use other resistances e.g. 0-90
Ohm, 73-10
Ohm, etc.
4. Disconnect Pink Wire from Sender on Fuel Tank.
5. Test continuity of Pink Wire.
Zero Ohms from Tank End to Gauge End - If not, repair or replace Wire.



6. Measure Resistance from Sender Terminal (on Tank) to Ground on Tank.



Should read as per (3) above - If not, replace Sender.
