[CA] Dragonfly 7 Blowing Fuses

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Kwallace,

The symptom does indeed appear to be symptomatic of a fault within the Dragonfly display's power/transducer cable. If the product is still under warranty, then it would be recommended that the power/transducer cable be sent to Raymarine’s Product Repair Center to be bench checked / serviced. Otherwise, the problem may be worked around be installing a Dragonfly transducer extension cable. If electing to attempt the latter solution, then the power leads of the Dragonfly power/transducer cable would be disconnected from power and ground. Instead, the power and ground leads of the Dragonfly transducer extension cable will be used to power the Dragonfly display.
