Adjustments:
The "Centroid" sender has two adjustments:
• EMPTY: Adjusts for length of sender. It has been set at the
factory, covered with a sealant and should not be changed.
• Full Adjustment (FULL): The full adjustment can be used to
correct for slight differences between fuel meters. During
installation, it 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. Adjust slowly, rotate counterclockwise, until the full
mark on the gauge is reached. The intent is to always adjust downscale rather
than upscale.
Troubleshooting:
A. Electronic Output: The sender has a transistorized output
to prevent an ohmmeter from getting a correct reading of its
output resistance.
B. Fuel Only: The sender will not work correctly in conducting
fluids such as water (it will read above full all the time in
water). One possibility is that when there is a constant
above-full reading there may be water in the bottom of the fuel
tank.
C. Contact Centroid: Probably 90% of the return Centroid tests
work okay on the bench. If you have incorrect readings contact
Centroid (telephone: 800-423-3574, or preferably,
fax: 386-423-3709) with the symptoms. A short,"fill in the
blanks" troubleshooting test is provided to test the sender. It is
easier to find the problem that way than after the sender has
been removed from the system, since the problem is not
necessarily with the sender.
