Condenser Unit Wiring Question

I'm more of a commercial HVAC controls guy, but I have an idea of how a residential condensing unit works. Any insight from a expert would be appreciated.
I'm tearing apart a condensing unit I got for free after the compressor seized up. It was under warranty and the factory said to scrap it, so I thought it would be interesting to dig into.
On the fan, it shows this:
Does that mean that the brown wire gets energized when the fan gets power? I'm assuming so since the brown goes to the capacitor and then off to the compressor? Thanks for any help.

Yep. It is a PSC permanent split capacitor type motor. Google that for more info.

Condenser Unit Wiring Question

I was working with a friend and he pulled wire off but didn't see where, I have two capacitors one large one and small one its on my g+ photos the large one is wired but the small one is not so I think a black wire should be on one end of capacitor to charge it or does that supplied by one of the two brown wires from the fan motor??its driving me crazy!Please anyone!!TY
