Ken,

This is truly the curse to end all curses. I've known that sick
feeling.
We manic-depressives just walk out, slamming the door, and don't
go
back in for a long time. It doesn't help, of course.
Well, you've got to find the cause or scrap that motor and start
with
another unit. There's something basically wrong somewhere.
I'll offer any help that I can, of course. Remember, big boys
don't cry!
They get revenge!

Gary Kosier
