Fuel Gauge
The fuel gauge can be tested using a new gauge as a
substitute or by the use of a DC voltage source and a
variable resistance box.
CAUTION
Make sure the voltage source is turned OFF be-
fore connecting it to the electrical circuit toavoid
electrical shock and prevent damaging the
gauge.

Note:
When reading the gauge test point, there are
two white dots on the gauge face below the edge of the
glass cover for the each test point. For each variable re-
sistance setting, the needle must be pointed between
the two white dots.

Take test point readings (Fig. 34).
IMPORTANT: Allow circuit to warm up for at least 5
minutes before taking test readings.

the left edge of the red area (empty).
B. Set variable resistance to 33 ohms. The needle
should point to the right edge of the green area
