[RE-wrenches] advice on testing turbine on tower

[boB at midnitesolar.com]

Ron,
Depending on the Clipper version,  there may be a jumper.... One of 3 in 
a row in the front of the
Clipper circuit board that, if installed on the right, may be making the 
Clipper try to turn on its auxiliary
power supply at a very low voltage when the turbine isn't spinning fast 
enough to
get over that hump.   Sometimes that can have a loading down effect on 
the turbine
before it has enough ~Ooomph~ to overcome that draw.

Lablelled  J1, J2 and J3  in-between the PWM input connector and that 
Batt In connector.
Just remove the jumper and maybe hang it on one of the pins to hold it 
or toss it.

If that doesn't help, disconnect the Classic from the Clipper/Turbine to 
make sure that is not the problem.

See if that helps.

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?
