2022 Yamaha AR 195 display screen, completely black.. connext screen

[Hbjrico]

So today I disconnected my batteries to charge them for our trip when I wired them back up, and I started my boat. I noticed that the screen never came on everything else works all accessories work the bilge pump, blower, horn, and navigation lights. Boat turns on just fine but just no display. It’s completely black like there’s no power to it. I checked the two fuses by the batteries. There’s one fuse for the build and a second fuse I believe is for accessories, but no luck. Any ideas where I can find another point to look at?

You need a wiring diagram to check if you are getting power to the connext. If so you shorted the screen. They do not like voltage fluctuations. Seen this happen before when changing batteries.
