Standard Resistance of Fuel Gauge Unit
(1) Check that resistance
value
between the fuel gauge
terminal and ground terminal is at standard value when fuel
gauge unit float is at point (highest) and point (lowest).
Standard value: Point 3
P o i n t
(2) Check that resistance value changes smoothly when float
moves slowly between point (highest) and point
(lowest).

Connect fuel gauge unit ‘to battery via test light
Immerse in water. Condition good if light goes off when unit
thermistor is in water and lights when unit is removed from
