Trouble with KISS wind generator

Directly after returning to our boat after hurricane Dorian passed Cape Canaveral I noticed the KISS wind generator, high up the main mast, had stopped rotating. I switched it off before we left, to put it into freewheel. The wind speed at the height of the hurricane was about 100 mph locally, so it probably went crazy.
I went up the mast to see if it was just stuck. It was stiff but possible to turn by hand, but even in 15 knts it would not spin on it’s own.
Does anyone please have any hints what to do?
It sounds like bearings to me, could they have overheated and failed in that speed wind?
It’s a devil of a job to get down and back up.

It’s been flawless for ten years I’ve owned the boat.
Thanks in advance. JR

Re: Trouble with KISS wind generator

On our KISS the brake switch would only stop the generator spinning up to 30-35 knots of wind. Above that there was enough rotation force to get it spinning again. We took to tying the blades when we received a storm forecast. Water under the bridge for you, but it is sounds like bearings. I know for sure that it would start spinning again at wind speeds well less than hurricane, I would suspect that things got very hot. They're not too hard to replace, but as you said, removing and re-installing will be the time-consuming bits, but I think that's where you need to go.

Re: Trouble with KISS wind generator

We have owned our KISS for 15 years and always tie it off before leaving the boat for any length of time or in a storm. The brake does not work above 25 knots and it just howls like a banshee.

I am afraid you will need to split the case and get into it to see what maybe the problem.

Good luck
