Troubleshooting
Possible solutions
1. Check condition of relevant fuses and breakers and connections,
replace if necessary (Refer to the
your product's installation instructions for fuse ratings.)
2. If fuse keeps blowing check for cable damage, broken connector pins
or incorrect wiring.
1. Check that the power cable connector is fully inserted into the unit
and locked in position.
2. Check the power supply cable and connectors for signs of damage or
corrosion, replace if necessary.
3. With the unit turned on, try flexing the power cable near to the display
connector to see if this causes the unit to re-boot/loose power,
replace if necessary.
4. Check the vessel's battery voltage, the condition of the battery
terminals and power supply cables, ensuring connections are secure,
clean and free from corrosion, replace if necessary.
5. With the product under load, using a multi-meter, check for high
voltage drop across all connectors/fuses etc, replace if necessary.
The power supply may be wired incorrectly, ensure the installation
instructions have been followed.
With the product under load, using a multi-meter, check the power supply
voltage as close to the unit as possible to establish actual voltage when
the current is flowing. (Refer to the
product's installation instructions for power supply requirements.)
Possible solutions
See possible solutions from 'Products does not turn on or keeps turning
off' above.
1. In the unlikely event that the products software has become corrupted
please try re-flashing the latest software from the Raymarine website.
2. On display products, as a last resort, you can try to perform a 'Power
on Reset', however this will delete all settings/presets and user data
(such as waypoints and tracks) and revert the unit back to factory
defaults.
