Power up troubleshooting

Blown fuse / tripped breaker:

1. Check condition of relevant fuses and breakers and connections, replace if necessary. (Refer to the Technical Specification section of your product’s installation instructions for fuse ratings.)

2. If fuse keeps blowing check for cable damage, broken connector pins or incorrect wiring.

Poor / damaged / insecure power supply cable / connections:

1. Check that the power cable connector is correctly orientated and fully inserted into the display connector and locked in position.

2. Check the power supply cable and connectors for signs of damage or corrosion, and replace if necessary.

3. With the display turned on, try flexing the power cable near to the display connector to see if this causes the unit to restart or lose power. Replace if necessary.

4. Check the vessel’s battery voltage and 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, and replace if necessary.

Incorrect power connection:

The power supply may be wired incorrectly, ensure the installation instructions have been followed.

Power supply and connection:

See possible solutions from the table above, entitled ‘Product does not turn on or keeps turning off’.

Software corruption:

1. In the unlikely event that the product’s software has become corrupted, try downloading and installing the latest software from the Raymarine website.

2. On display products, as a last resort, attempt to perform a ‘Power on Reset’. Be aware that this will delete all settings / presets and user data (such as waypoints and tracks), and revert the unit back to factory defaults.
