[RE-wrenches] advice on testing turbine on tower

[Ron Young]

Thanks Ryan, there is a new Midnite arrestor in the Clipper and I don't think that is the prob. but will check. There are two Delta LA's in the main Outback panel and I don't think they're involved.

The wind turbine would not spin, it was as if the brake was on - if you know the Whisper, the brake is electrical, basically a shorting of the three phases. When the turbine was disconnected from the controller it would spin up and produce voltage at the leads. So the controller was replaced with a Clipper and Classic and the same problem still exists. I have resisted pulling the turbine down as it is a complicated sidehill installation but it looks like it will have to be done. Before I do that I thought I'd throw this out into the Wrenches community to see if anyone could offer suggestions. My conclusion is that there is some kind of short in the electronics in the turbine that only shows up when it is under load, i.e. has a battery connection. Suggestions, ideas?
