No power to main screen and speedometer-2015 Moomba Mondo

[Cgray21]

I have a 2015 Moomba Mondo that does not get power to the main screen and speedometer. The RPM gauge lights up. Also, the motor will not turn over and none of the accessories or switches work besides the radio. Any ideas?

Jumpering the battery with a known good battery not correct the problem?

The battery is brand new. I went and got a new one just in case the battery was bad because I tried jumping it and nothing changed.

There are two breakers in this boat. They may have tripped. One is located next to the battery bank and the other one in the engine compartment behind and below the ski pylon. Press the reset button on each of them and toggle up the lever on the breaker to activate.
If this doesn’t work ensure the DIN plug (make plug) from the wiring harness is fully seated in each gauge. Temperature fluctuations at this time of year can ‘unseat’ the plug if they aren’t fully compressed.
Hope this works!

I got all the gauges working and the main screen. The toggle switches light up but none of them work. The same thing with my motor turning over when I hit the key. My engine hours say zero now for some reason. Could the computer screen cause the issue with the power to everything? I checked my relay box on top of the motor and it is not getting any power there either. I checked the fuses underneath the dash and the two breakers

This sounds like a bad connection. I would check the battery switch and main bus bar voltage. Could be a partially failed breaker on that circuit.
