Matt Sounds like you have checked everything. How about the wiring coming from the brush holder? Make sure none of them have been chaffed near the pivot. Of course the brushes might show some arcing too if there is an intermittent short. If you need an upper casting, complete with stator and armature, contact me off list. Also what is the resistance phase to phase of the armature? Jeremy Rodriguez All Solar Sent by Jeremy's iPhone.

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.
