Fish 4430/4431 Installation and Operation Manual
This troubleshooting guide is written with
the assumption that the user has read and
understood the relevant sections in this
manual.
It is possible in many cases to solve difficulties
without having to send the display unit back to
the manufacturer for repair. Please follow this
trouble-shooting section before contacting the
nearest NAVMAN dealer.
There are no user serviceable parts.
Specialised methods and testing equipment
are required to ensure that the display unit is
reassembled correctly and is waterproof. Users
who service a NAVMAN fishfinder themselves
will void the warranty.
Repairs to the FISH 4430/4431 may only be
carried out by a service centre approved by
NAVMAN. If the display unit must be sent into
a service centre for repair, it is essential to
send in the transducer(s) at the same time.
More information can be found on our
Website: www.navman.com
1. The fishfinder won’t turn on:
a) NAVMAN fishfinders are designed to
operate on 12 volt battery systems, where
the voltage may vary from 10 to 16.5 volts.
If an excessive voltage is supplied to the
unit, a resettable fuse will be tripped,
turning the display unit off.
b) Check that the power cable LT connector
at the back of the display unit is securely
plugged in and the collar is locked in place.
The collar must be secure for watertight
connection.
c) Measure the battery voltage while the
battery is under load - turn on some
lights, radio, or other electrical equipment
connected to the battery. If the voltage is
less than 10 volts:
- The battery terminals or wiring on the
terminals may be corroded.
- The battery may not be charging correctly
or may need replacing.
d) Inspect the power cable from end to
end for damage such as cuts, breaks or
squashed sections.
e) Ensure that the red wire is connected to the
positive battery terminal and the black wire
to the negative battery terminal. If wired for
the Auto Power option, ensure the yellow
wires are connected to ignition circuit. Also
check the boat’s main switch circuit (see
section 5-4).
f) Check for corrosion on the power cable LT
connector and clean or replace if required.
g) Check fuses that are placed in line with the
power cable. A fuse can be blown despite
appearing to be good, or the fuse may be
corroded. Test the fuse or replace it with a
fuse known to be good.
2. The fishfinder won’t turn off:
The fishfinder may have been wired with
the Engine Hours feature enabled. In this
case, the fishfinder cannot be turned off
while the ignition power is on. (See Auto
Power Wiring in section 5-4).
3. The fishfinder 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
running 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 postion. (See the
Transducer Installation Guide for more
information).
c) When in water less than 2 feet (0.6 m) the
bottom and depth readings may become
inconsistent and erratic. This depth is
measured from the transducer and does
not allow for any keel offset setting.
d) Manual Gain may be set too low, which may
cause weak bottom echo, or no fish signals.
If Auto Gain is disabled try increasing the
gain.
