Problems at power up and their possible causes and solutions are described here.
Product does not turn on or keeps turning off
Possible causes
Possible solutions
Blown fuse / tripped breaker
1.
Check condition of relevant fuses and breakers and connections, replace if necessary (Refer to
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 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.
Incorrect power connection
The power supply may be wired incorrectly, ensure the installation instructions have been followed. (Refer to
for cable and connection requirements.)
Power source insufficient
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
Chapter 12 Technical specification
for power
supply requirements.)
Product will not boot up (re-boot loop)
