Possible causes Possible solutions
Blown fuse / tripped breaker
1. Check condition of relevant fuses and breakers and
connections, replace if necessary (Refer to
Chapter 13
Technical specification 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
Chapter 4
Cables and connections 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
