I think the white cup hook is just a red herring. Jackie is testing us in our problem solving skills.
I agree with BobJ's advise that making a secure reconnection of the the red/blue wire connector may just do it. On one occasion, I found that connector loose.
This may have legs. Don't blow it people.
This forum. I can never figure out why one thread triggers a response while others don’t. For instance, why the fascination with an image of a white cup hook? Dunno. One interpretation is that singlehanders are detail-oriented individuals who are able to problem solve using practical items aboard their boats in ways that may possibly save their lives offshore. An alternative scenario is that it has been raining here in the Bay Area and no one can sail, so SSS members are reading this forum with itchy fingers. Remember that, before Robin Knox-Johnson left for his solo circumnavigation, he was interviewed by a psychologist, who announced him “distressingly normal”. So you can never really tell.
Here’s another image for those of you who would like to be psycho-analyzed by singlehanded sailors. What do YOU see?
