NR Series FUEL  FUEL SENDER GAUGE ASSEMBLY  INSPECTION  


PROCEDURE

Hide 83320 1.INSPECT FUEL SENDER GAUGE ASSEMBLY

CAUTION:

Perform the inspection in a well-ventilated area.

Do not perform the inspection near an open flame.


a.

Check that the float moves smoothly between F and E.


b.

Check the fuel sender gauge assembly voltage.

(Fuel Sender Gauge Assembly)
*b Voltage Applied between Terminals


Apply 5 V between terminals 2 and 3.

NOTICE:
·

Be careful when connecting the leads, as the fuel sender gauge assembly may be damaged if the leads are connected to the wrong terminals.

·

Do not apply more than 6 V to terminals 2 or 3.



HINT:

If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series.

Measure the voltage according to the value(s) in the table below.

Standard Voltage:
Tester Connection Float Level Specified Condition
1 - 2 F 4.255 to 4.605 V*
Between F and E 0.345 to 4.605 V* (Gradually changes)
E 0.345 to 0.695 V*


*: The output voltage changes depending on the voltage applied to the terminals.

Output voltage (F) = (0.851 x Voltage applied to terminals) to (0.921 x Voltage applied to terminals)

Output voltage (E) = (0.069 x Voltage applied to terminals) to (0.139 x Voltage applied to terminals)

If the result is not as specified, replace the fuel sender gauge assembly.
