[CA] [CA11] Fishfinder low voltage issue

Welcome to the Raymarine Forum Paulo,

The low voltage alert will be generated if the MFD is receiving insufficient power (voltage x current). Insufficient current may result from depleted or weak batteries, or poor electrical continuity within the power and/or ground circuit used to supply power to the MFD. Troubleshooting should begin by inspecting the connections within the power and ground circuits from the MFD, though any power distribution panel, bus bars, etc, to the batteries to ensure that all connections are free of corrosion, tight, and provide good continuity. The vessel should then be connected to shore power, the vessel's batteries should be permitted to achieve a fully charged state, and then while still connected to shore power, the system should be tested. Should the problem persist, then the loaded system voltage being supplied to the MFD should be measured at the MFD's power plug. Should the measured voltage be greater than 10.6 VDC and should the problem persist, then it would be recommended that the MFD be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
