Radar problem

[cagey]

What a pre season I’ve had, today had a quick run through of electronics ahead of screwing everything down ready for leaving boatyard.
Northstar plotter just returned after quick repair on GPS, fitted last week and functioned perfectly, today turned it on everything worked as it should except radar, screen showed “ radar not found” , could this be connected to storms over the weekend, boat wasn’t hit nor was boatyard or area around but just curious how this could happen without any warning.
Not my best begining.

More likely to be contact issues/bent pins in the radar connector to the plotter.

Is the radar itself powered up and working? On my Furuno, the rotation of the antenna when switched on is audible.
Could be a blown/ corroded fuse

Check the voltage at the plotter when switched on. On occasions my radar won't function because the battery voltage has slipped below what is required to make it work. Once the engine's running or the shore power connected the it works....
