TRACKER 5505/5505i/5605 Installation and Operation Manual 62 NAVMAN
1-1 The TRACKER won’t turn on:
a The TRACKER is designed to operate on
a 12/24 volt battery system, where the
voltage may vary from 10.5 to 32 volts. If
an excessive voltage is supplied, a fuse will
be tripped, turning the display unit off.
Check the fuse.
b Check that the power cable 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, squashed
or trapped 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
wire is connected to the ignition circuit.
Also check the boat’s main switch circuit
(see section 15-4).

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
troubleshooting section before contacting the
nearest NAVMAN dealer.
There are no user serviceable parts. Specialized
methods and testing equipment are required
to ensure that the display unit is reassembled correctly and is waterproof. Users who service
the product themselves will void the warranty.
Repairs to the product may only be carried out
by a service centre approved by NAVMAN. If the
product must be sent into a service centre for

at the same time.

f Check for corrosion on the power cable
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.

The TRACKER may have been wired for
Auto power. In this case, the TRACKER
cannot be turned off while the ignition
power is on (see section 2-3).

nothing is displayed:
The TRACKER may be operating, but the
backlight settings may have been set too
low (see section 2-4).
