Power up troubleshooting

Blown fuse / tripped breaker

1. Check the fuse, located inline with the power cable. Ensure that it has the correct rating (refer to the Inline fuse and thermal breaker ratings section), as an under-rated fuse can affect the power supplied to the product. If the fuse has blown, replace with a new fuse.

2. Check the condition of relevant / additional fuses and breakers and connections; replace if necessary.

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

Poor / damaged / insecure power supply cable / connections

1. 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.

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

3. Check that the power cable connector is fully inserted into the unit and locked in position.

4. With the unit turned on, try flexing the power cable near to the connector to see if this causes the unit to re-boot/lose power; 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

1. The power supply may be wired incorrectly; ensure that the installation instructions have been correctly followed.

Power source insufficient

1. Check that your power supply (battery or distribution panel) is providing a minimum of 10.8 V to each component in the system.

Power supply and connection

1. 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. Refer to your multifunction display / chartplotter’s operation instructions for details on updating software for connected devices.
