The Centroid fuel sender has no moving parts. It works by measuring capaci-
tance, an electrical property, between its inner and outer tubes in the tank. The
more fuel between the tubes, the higher the reading. Electronics in the hockey-
puck head of the sender convert the capacitance to current to drive the fuel
gauge.
CONNECTIONS
The Centroid sender has 4 connections:
• Positive
and
Negative
: Battery voltage to run the electronics in the sender
head.
• Send:
Connects to the Send terminal of the gauge on the dash.
• Alarm:
Makes a connection internally to the Negative terminal when the low
alarm fuel level is reached (when gauge is reading about 1/8 tank). This turns on
the alarm light on the dash. It is not adjustable.
ADJUSTMENTS
The Centroid sender has 2 adjustments:
Empty
: Adjusts for length of sender. It has been set at the factory and covered
with a sealant. It should not be changed.
Full Adjustment
: The full adjustment can be used to correct for slight differ-
ences between fuel meters. During installation, is has been calibrated for your
meter and should not need readjustment.
The correct adjustment technique, with a full tank of fuel, is to start with the
full adjustment screw completely clockwise. This should cause the reading to be
above full. Then adjust slowly counterclockwise until the full mark is reached.
The intent is to always adjust downscale rather than upscale.
