e125 intermittent power off

Todd,

The "Supply Voltage" reported within the MFD's diagnostics will normally report a voltage level which is approximately 1V below that of a 12V power circuit supplying the MFD. Per the FAQ referenced within my initial response, the MFD should be isolated from other high current drawing devices. It appears that the windlass is minimally on the same power circuit or possibly the battery switch was in the Both position when the previous windlass operation caused the MFD to reboot. The FAQ referenced within my prior response identified some products which may assist with such isolation. Should the windlass or any other high current drawing device which is not part of the marine electronics system be powered by house battery, then you may want to consider installing a product such as Newmar's Start Guard between the marine electronics and the circuit which is supplying them with power.
