TRACKER 5430/5430i Installation and Operation Manual
13 Fuel Used or Remaining seem wrong:
a The engine has been run while the TRACKER
is turned off and it has not recorded the fuel
use. Wire the auto power option (see section
15-3).
b Fuel may be surging back and forward
through a transducer in rough seas. Try
installing a one way valve between the fuel
transducer and the fuel tank.
c Tank Full or Set Remaining has not been set
every refuelling.
d When refuelling, air pockets may have
prevented the tank filling completely.
e Fuel transducers wear out over time and
should be replaced every 5000 litres
(1316 US gallons) of fuel as a guide.
14 No or low fuel flow reading:
a Check the fuel cable connectors are securely
plugged in and the locking ring is locked in
place.
b Clogged fuel transducer. To clean a
transducer, remove it from the line and gently
blow through it in the opposite direction
to the fuel flow. Fit a fuel filter before the
transducer.
c Inspect the fuel cable(s) for damage.
d Dirty fuel filter.
e Fuel transducer has been exposed to
excessive heat or vibration.
15 Only one flow rate value shown for a twin
engine installation:
Set Num Engines to 2 (see section 13-4).
16 Erratic fuel flow readings:
a The fuel transducer must not be mounted too
close to the fuel pump(s) and not subject to
excess vibration.
b Check for air leaks in the fuel hose(s) or fuel
pick-up(s) in the tank(s).
c The Flow Filter has not been set to suit the
engine(s) (see section 13-4). Increase the
Flow Filter value until a steady flow rate is
indicated.
17 TRACKER operates erratically or
unexpectedly:
Setup data incorrect. Reset to factory
defaults (see section 13-1).
