Installation and Operation Manual
85
3-2 Flow indicates no fuel or low fuel:
a Check that the number of engines is set to
1 (see section 17-5).
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 17-5).
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 17-5).
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.
B-4 Sonar fishfinding problems
4-1 The Instrument operates erratically:
a Check that the transducer does not have
debris (e.g. weed, plastic bag) caught
around it.
b The transducer may have been damaged
during launching, running aground or
while underway with debris etc. If the
transducer has been impacted, it may
have been kicked up on the bracket. If
it is not physically damaged, reset the
transducer back to its original position.
(See the
Transom Transducer Installation
Guide
.)
c When the transducer is less that 2 ft
(0.6 m) from the bottom, the depth
readings may become inconsistent and
erratic.
d Manual Gain may be set too low, which may
cause weak bottom echo or no fish signals.
If in Manual Gain, try increasing the Gain.
e Ensure the back of the bottom surface
of the transducer is slightly lower than
the front and the front is as deep in the
water as possible in order to minimize the
generation of bubbles through cavitation.
(See the
Transom Transducers Installation
Guide
)
f Check the transducer and power cable
connectors at the back of the display unit
are securely plugged in and the collars
are locked in place. The collars must be
secure for watertight connection.
g Inspect the power cable from end to end
for damage such as cuts, breaks, squashed
or trapped sections.
h Ensure there is not another fishfinder or
depth sounder turned on, which may
interfere with this Instrument.
