Hey All:

I got my 7.5HP rotary working today with three nice phases showing up on the outputs. With one huge issue. There's 80+V AC showing up on the case of the electronics box. The only thing touching the case metal are the run time caps. Each leg has .130F of oval metal can caps in parallel. Is this where that voltage is showing up? Is this a regular problem with these things? Is it standard to insulate them from the case electrically? Everything else is isolated.
Are these AC eddy currents induced by the high current running between the cap banks? Will a short to outside ground solve this problem. I'm afraid to touch it and use a broom handle to control things.

And ideas would be welcome.

Andrew
