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

[Matt Sherald]

I've got a Whisper that's not performing and I'm putting this out to the group in hopes that someone has had a similiar dilemma.

My line to line voltage measurements are the same between the three phases.  However, my line to ground measurements are consistent across only two of the phase-ground combinations.  The third phase appears to be shorting to ground.

I had the tower down and took the machine off to check the split bolt connections at the top of the tower for wear/rubbing.  The down tower wiring checks 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.

With no tech support to turn to I am hoping that someone in the Wrench community might have had a similiar conundrum at one time.  I'd appreciate hearing from you if you have.

Many thanks in advance.
