[RE-wrenches] SWWP Whisper 200 - Looking for a Short to Ground

[Ron @ earthRight Solar]

Hi Allan, although I seem to be subscribed to the small wind forum I have never received an email or digest from that list. I went online to see if I could find archived posts just to see if there actually was a small wind forum and couldn't navigate my way through the list page to find anything like an archive although I did confirm my subscription and digest option selection. I just assume it isn't a very active list but if it is I'd like to check it out.

I don't know if Matt has had better luck.

>> Hi Matt, I have a very similar (maybe identical) problem with a Whisper 200 that I've been trying to solve for several weeks. When you say that it's not performing what exactly do you mean?

The turbine still just spins slowly as if the brake switch was on and only ramps up when leads are removed to the controller. I've double checked the wiring, dropped the turbine and checked the brushes, stator, connections etc. everything checks out. The batteries are weak but still showing acceptable voltage above 48v. I'm also at a loss. I've had a couple of discussions with the guys at renewable energy supplies and they seem to be knowledgeable but I still can't sort it out. Anyway maybe give these guys a call: http://renewableenergysupplies.net/index.html

I opened the wire access on the machine to double check wire insulation and the wire nut connections.  I unbolted the slip rings and checked for any sign of a smoking gun there.  Nothing jumped out at me during the inspection and I'm curious if it might be in the spinner assembly.
