Yeah, that's what the diagram shows in Figure 2, all right. I'm used to the
configuration they show in Figure 1. Figure 2 makes sense to me only if the
motor case is grounded, but grounding the case seems like a bad idea.

It seems like that would only work if the motor case was grounded, and there
are good reasons why you don't want to

Actually, thats what i did, and i'm pretty sure thats what all the
diagrams told me to do. Seems crazy, but thats the recomendation.
One cap going from + to -, one cap going from + to case, one cap going
from - to case. I found multiple articles suggesting this. Here is
the link to one article: http://www.teamdelta.com/pdf/tde_an1.pdf
So far, i just did it to my 'test' motor. I figured i'd use an extra
motor in case i messed up, or couldn't put it back together, but i
figured that part out. I figure this, along with the new automotive
relays with diodes in them, should do the trick, or else its back to
the drawling board.
