With fuel level going down, the slide contact (1) on float (2) of immersion tube indicator increases the resistance value, the voltage will drop and the indi\u00adcating needle in instrument will therefore swing back.<\/div>\n
If the fuel level goes down still further, the reserve warning contact (5) in immersion tube indicator is closed and will connect reserve warning lamp to ground, which will then light up.<\/div>\n<\/div>\n<\/td>\n

The circuit has been modified starting September 1982. The reserve warning lamp will light up with ignition switched on (checkup). As soon as engine starts, the lamp will go out, if the fuel tank holds more than the reserve fuel.<\/div>\n
Note: <\/strong>During checkup, the reserve warning lamp will light up weaker, with reserve stronger.<\/div>\n<\/div>\n<\/td>\n
