Garmin Display Dead

[Cctvdc]

2018 R7 Out on boat today and display on both screens are blank. Looking into it found no power to each screen. I was able to grab 12 Vdc from under dash and feed power to Garmin and they displayed properly. I thought I have seen something on this forum as to a relay being a possible cause ?

Relay gets bumped behind the helm. (Where the radio amplifiers are, I believe). I haven't had that problem yet but anticipating it.

(Or sometimes they go bad)

Bad relay that powers up the display. Common problem. The only issue is there are maybe 2-3 of these relays behind the dash and Cobalt is useless in telling you which one powers the displays. Where mine is located may not be where yours is.

Thank You for responses, Does anyone have a wiring diagram for an 2018 R7 or direct me to a source ? I have all user manuals from the original purchase of our boat but no electrical diagrams. Went on Cobalt support and just saw user manuals I have.

Update on display easy and no cost fix. After getting wiring diagram from Cobalt and looking at them it showed a circuit breaker panel that I was unaware of located in front of the helm in the swing up sea storage very well tucked behind the fender storage. Inspected area and found the cover to the panel had come off from everything we packed in there for a day on the boat. Also on the floor was a circuit breaker that had come out of block assembly. Lesson learned look for the obvious first.
