Wind Generator Control Board Blown

I have an Air-X style wind generator stuck in wind-break mode.

Upon closer inspection, it appears that the controller board had a fried component (C8) (you can still see the smoked area in the attached photo).

I think this component was a surface mounted capacitor (just a guess). The component was removed in the photo.

The board is a RevE4.3. I was wondering if anyone had a circuit diagram for this board or happened to know what component goes at spot C8 and what the specifics for the component are?

Thanks in advance...

If you could post a pic of the whole board, but as close as possible to give a bigger pic, I'll give it a shot.

Re: Wind Generator Control Board Blown

These boards have programmable chipsThat lose theyre programming quite easily and sw answer is to sell you a new board. Wrist/ chassis grounding must be used.Online there is a guy reverse engineering these boards(which change often). Will take some looking to find page.Look here or a simple answer to these frail boards.

Re: Wind Generator Control Board Blown

"Stuck in the wind-brake mode" Sort of indicates more than a blown cap!! It might be best to get a replacement board. I would be checking the diodes for a short as something other than a blown cap is shorting the windings. At least check there is no bridge where the cap was located.(tooth brush & metho to remove that blacken area before inspection). There has been a very high voltage across that cap. check Wind Generator: Air-X 400, 12 volt regulator circuit board troubleshooting.

This does seem to fit your description.

regards Bill
