Power up troubleshooting
Before troubleshooting problems with your power connection, ensure that you have followed the power connection guidance provided in the product’s installation instructions and performed a power cycle/reboot of the device. The troubleshooting information below can be used if you are experiencing problems with powering up your product.
Blown fuse / tripped breaker
Check the fuse, located inline with the power cable. Ensure that it has the correct rating (refer to Connections chapter), as an under-rated fuse can affect the power supplied to the product. If the fuse has blown, replace with a new fuse.
Check the condition of relevant / additional fuses and breakers and connections; replace if necessary.
If fuse keeps blowing, check for cable damage, broken connector pins or incorrect wiring.
Poor / damaged / insecure power supply cable / connections
Check that the power cable connector is fully inserted into the unit and locked in position.
Check the power supply cable and connectors for signs of damage or corrosion, replace if necessary.
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.
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.
Incorrect power connection
The power supply may be wired incorrectly, ensure the installation instructions have been followed.
Power source insufficient
Check that your power supply (battery or distribution panel) is providing a minimum of 10.8 V to each component in the system.
