Troubleshooting:
A. Electronic Output: The sender has a transistorized output. This
prevents 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: 904-423-3709)
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.
Make a visual check for fuel leaks at all engine-mounted fuel lines,
connections and at the fuel tank pick-up and return lines. Leaks in this area
may best be detected by checking for accumulation of fuel under the tank.
Engine performance and auxiliary equipment is dependent upon the ability of
flexible hoses to transfer lubricating oil, air, coolant and fuel. Maintenance of
hoses is an important step in ensuring efficient, economical and safe operation
of the engine and related equipment.
INSPECT: Check hoses daily as part of the pre-start inspection. Examine
hoses for leaks. Check all fittings, clamps and ties carefully. Make sure the
hoses are not touching shafts, couplings or heated surfaces, including exhaust
manifolds, sharp edges or other obvious hazardous areas. Over time, vibration
from the engine and road can move or fatigue clamps and ties. To ensure con-
tinued proper support, inspect fasteners frequently and tighten or replace them
as necessary.
Three filters are used for the engine. These are; a reusable pre-filter, primary
and a secondary filter. The reusable pre-filter and primary filter is located in
the engine compartment. The secondary filter is located on the engine. Prime
the fuel system when filters are changed or if the engine has run out of fuel.
