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

[Ron Young]

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?

My problem surfaced following a lightning storm and everything pointed to the controller. I replaced the controller with a Clipper & Classic. 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

Will be interested to hear how you make out.

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.
