FUEL GAUGE UNIT CHECK



FUEL GAUGE UNIT FLOAT HEIGHT



NOMINAL RESISTANCE OF THE FUEL GAUGE UNIT


1.Remove the fuel pump and gauge assembly <Diesel> or fuel pipe and gauge assembly <Petrol> (Refer to GROUP 13D, Fuel Tank ).


2.When float of the fuel gauge unit is in stopper positions "F" and "E", ensure that resistance between the fuel pump and gauge assembly <Diesel> or fuel pipe and gauge assembly <Petrol> terminal and earth terminal is within the standard value.
Standard value <Petrol>:
Float position
Gauge resistance (Ω)
Stopper position "F"
13.0 ± 1
Stopper position "E"
120.0 ± 1
Standard value <Diesel>:
Float position
Gauge resistance (Ω)
Stopper position "F"
13.0 ± 1
Stopper position "E"
120.0 ± 1
3.When the float is moved slowly between stopper positions "F" and "E", ensure that the resistance is smoothly changing.
