I can't say I have been here long, or even sailed for many years. I find the "windicator" helpful to improve my skills, and even more so, my Admiral uses it when at the helm so we can keep moving while I am doing something else, like eating, using the head, checking things, etc. Without it, we seem to have a luff problem... I know, novices.
I have just replaced my pre-Raymarine TakTik wireless battery/solar panel for the second time, as the wires had fallen off the board the first time without me realizing it. The fix you need to do is very easy, as has been described. There is a youtube video by a well respected cruiser showing the replacement procedure of the cups, etc. I found it helpful as he also replaced his battery. The video was by the late Patrick Childress/Sailing Brickhouse. His videos were often spot on, and very helpful for many tasks onboard. Unfortunately, he passed due to Covid last year.
As to the wireless, well the thing is toast again. So, I will be buying a new one so we can see wind speed and direction where we fail to fully appreciate all the readily identifiable clues to this information everyone else seems so adept at seeing....
Good luck.
