I
terminal and ground terminal is at standard value when fuel
gauge unit float is at point F (highest) and point E (lowest).
Standard value: Point F 3 +2 R
(2) Check that resistance value changes smoothly when float
moves slowly between point F (highest) and point E
(lowest).

Connect fuel gauge unit 'to battery via test light (12V-3.4W).
Immerse in water. Condition good if light goes off when unit
thermistor is in water and lights when unit is removed from
