New Turbines won't spin

I have a couple of turbines that won’t spin. My guys have been installing these for years and this has never happened before. It’s not a wormaniship issue.

The rest will continuously spin but the ones circled will stop if its not a strong wind. The turbines have been inspected and I don’t see anything mechanically wrong with them.

Now the client is concerned about our workmanship.

Roof pitch is 10/12

Any advise is appreciated :pray:

Should be a rod in the center and a bearing in the cap, if they aren’t lined up, the cap wont spin. if that’s all good, a little high temp grease should help.
