NMEA Network

[walleye284]

I just put the batteries back in the boat for the year, now I am not recognizing any of my nmea network devices. Should have evinrude engine info, ep10 fuel flow, and LGC2000. None of them are showing up. I assume there is no power to the network, but I don't know why. Any ideas?

Did you miss a red or black wire when connecting to the battery?

Do you have a master power switch you need to turn on to power the network?

Are any fuses blown on the network power cables?
