Possible solutions
1. Check condition of relevant fuses and breakers and connections, replace if necessary (Refer to
Technical specification 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. (Refer to
4 Cables and connections for cable and connection requirements.)
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
supply requirements.)
Possible solutions
See possible solutions from 'Products does not turn on or keeps turning off' above.
