Do you have other devices that are powered by NMEA2000? If so, do those devices work?
Thanks Rusty. Yes, all my other Raymarine Seatalk instruments are getting power and there didn't seem to even be a backlight glow on the ST70 display (but it was in bright sun and I was driving so I can't be sure until I go out to the boat this weekend and check).
What is odd is that I didn't do anything that would cause the cable to be bumped and during the prior days trip the display didn't falter at all during in the rough water.
