A few weeks ago, on our last outing, our depth/speed log, wind
and auto pilot screens all suddenly went blank, except for the pilot screen
showing the "SeaTalk Failure" message. The plotter and GPS
continued to function. This occurred during a rather heavy downpour, though it was not the first time we had been caught out in the weather
. A week or so later, they were working again, until yesterday when I switched them on and, again, same message though there had been no rain this time. Any ideas out there or similar experiences? I'm guessing/hoping it might just be a cabling connection issue.
