TRACKER 5380 Installation and Operation Manual 60 NAVMAN
Note: For the TRACKER to measure fuel
consumption, the optional fuel flow kit must be
fitted.
3-1 Fuel used or remaining seem inaccurate:
TRACKER is not wired for auto power (see
section 15-4).
b In rough seas, fuel may surge back and
forth through the fuel transducer, resulting
in incorrect readings. Try installing a
one-way valve between the fuel transducer
and the fuel tank.
c The Set remaining fuel value must
be reset after every refuelling (see section
10-1).
d The fuel tank may not refill to the same
capacity each time due to air pockets. This is
particularly noticable with underfloor tanks.
e Fuel transducers wear out over time and
should be replaced after every 5000 litres
of fuel.
3-2 Flow indicates no fuel or low fuel:
a Check that the number of engines is set to
1 (see section 14-4).
b Check that the fuel cable connectors are
securely plugged in and the collar is locked
in place. The collar must be locked in place
to give a watertight connection.
c A fuel transducer may be clogged. If so,
remove the transducer from the fuel line
and gently blow through it in the opposite
direction to the fuel flow.
A fuel filter between the fuel transducer
and the fuel tank must be installed as per
the fuel installation guide. Failure to do so
will void the warranty.
d Inspect the fuel cable from end to end for
damage such as cuts, breaks, trapped or
squashed sections.
e Check that the fuel filter is clean.
3-3 A twin engine installation shows only one
flow rate:
a Check that the number of engines is set to
2 (see section 14-4).
3-4 Erratic Fuel Flow readings:
a The fuel flow transducer may have been
mounted too close to the fuel pump or may
be subject to excessive vibration. Refer to
the installation instructions supplied with
the fuel transducer.
b Check for leaks in the fuel line or in the fuel
pickup in the tank.
c The Flow filter value is not suitable for
the engine. Check that the value is not set
to zero, then try increasing the value until a
steady flow rate is shown (see section 14-4).
3-5 There is no reading for fuel economy:
a The boat must be travelling through the
water to generate an Economy reading.
b Check that the paddlewheel on the
transducer is spinning freely and that the
two magnets in the paddlewheel are still
in place.
