Dead LINC screen after swapping battery selector switch

[Cadesun]

I had the dealer swap out my dying battery selector switch at the end of the season and now my LINC screen is dead. Anyone else have this issue? Could the dealer have shorted it while swapping the switch? Thanks.

Make sure the post fuse was put back on the battery selector.

No, it's unlikely the dealership could damage the screen by changing out the battery selector. The screen is protected from reverse power connection, and if they had done that somehow, other stuff in the boat would be damaged but not the LINC screen. If they did anything, they left something disconnected, but the screen shouldn't be damaged.

Did the screen come on ever since they switched the power selector? I can't imagine they didn't boot the boat up and make sure everything was running after changing that selector.

LINC screen runs off same Aux power feed as the stereo. Is the Stereo working?

If you have a voltmeter and want to check the power feed directly at the connector on the LINC screen. Then pop the black 23-pin connector off the screen.

Ground is pin 8,

Pins 7 and 15 should read 12v when the boat ignition is on. If they don't then there is problem with the power to the screen in the boat wiring. And that likely is something that got left disconnected by the dealer. Assuming the screen has never worked since the selector was changed.

If Power is on those pins, then the problem is the screen. For that generation LINC screen, the flash getting corrupted and the screen not booting is a pretty common problem. If that's the case, you should see the screen button backlight come on when the boat is powered up. Actually, that's the first thing you should check. Is the button backlight coming on? If so, then it's the screen. If not, then I bet the screen isn't getting power.

Thanks for the replies! Picking up the boat tomorrow from storage so I'll investigate based on the advice.

They did boot up the boat after replacing the switch and noted that the screen was dead and needed replacement. Hopefully they just forgot to reconnect something because it worked when I dropped the boat off.

Experienced dead screen, no backlight a year ago. Had a boat electrician stop by and he was stumped. He decided to unplug all wiring harness and cables going to/from the Linc. Gave each a blow of air, plugged back in, screen fired right up. Worth a shot. My boat was a 2014.

Thanks for all the input. I troubleshot it at the cottage, failed, took it to the Nautique dealer who troubleshot it again, also a no go. They tried to charge me $4,800 for the screen alone (no labor) but had quoted me $3,000 last fall. They honored the first quote but it was a good reminder to keep maintenance records!
