as the armada was not in use that much i didnt saw any problem with fuel gauge.

which was showing full tank when empty & empty when full.

so opened the tank to check the sensor which was OK.

after comparing it with other armadas sensor it the problem was solved.

electrician said to buy a new sensor but i thought what the hell another rs 300/-.

after thinking for a while finally solved the issue by bending the as shown by red arrow.

& now the meter shows (approx :p) correct reading.

 

also changed the wiper linkage assey.
which was not OE so had to do a little work to fit it.
