2017 Yamaha limited s connext : issue

[Ace_17yamaha212limiteds]

Help please...
I replace my batteries this weekend. My boat starts up fine . The only things that don’t work is my sound system , tacs and connext screen stays on Yamaha display. Has anyone had this problem?

I would start by checking battery voltages and connections. A picture of the connections may help a second set of eyes spot something wrong with the connections. As long as the battery switches were shut off during the changing of the batteries, then there should not have been any way to damage any components in the system. From your description, it really sounds like the House/system side is underpowered somehow.

Thank you for the input... I have it at the shop now. I'm hoping to get it fixed soon and hopefully the unit isn't shot it's on backorder until August

Update: screen was replaced it goes now. But now the screen is popping up with errs, pcu errs, and rpm tacs are going up down. Any suggestions how to fix this?
