sx210 electrical problems

[Rogerrowe]

I recently purchased a 2014 SX210 with 230 hours.the boat worked great for 2 weeks.
Then my speedometer stopped working and now my starboard tach doesn’t even light up.
I show a N2K as well as a speed comm error on startup on my port Tachometer.
I can’t imagine both Speedo and tach failure at the same time.
I did swap the port and starboard and the port tach powered up on the starboard connectors but the starboard tach still doesn’t power up on the port connectors.
Does the hull sensor control this?

Not sure if this helps any, from the service manual
how to confirm if the speed sensor is working.

As well as verify the meter voltage.

I will check this on the weekend and post my findings
