Thanks. Batteries are fairly new and solar keeps them up. I am concerned with the converted seatalk that provides power and the NMEA 2000 bridge that only allows one power source. Of course it all works most of the time. I also have every,thing wired to a single 15amp breaker but they are only pulling 3 amps.Check all the connections to make certain they are good.
A drop in voltage can cause electronics to power down. This an happen if there is a sudden increase in the load as well as if the batteries are old or in a low SOC.
You can contact B&G tech support, but they will probably blame it on the Seatakbridge.
Thanks. I am going to move the power for the Zeus to it’s own connection rather then shared with all the other instruments and see what happens. The only other thing I can think of is overheating, but it does power back on.
