Default Onan 5 OCCK-3CR/12016R

I wasn't actively looking for a genset, but my brother-in-law gave this one to me. It came out of a 1976 Beechcraft RV. It only has 275hrs on it. I'm not new to basic electrical or engines, but I haven't messed with gensets before.
I need some help identifying 2 parts in the pic below. I took all each one of the brush holders off to free up the brushes and clean the slip rings/commutator. When I put part #2(I think it's a diode) back on, I must've gotten it backwards. When I hooked the battery back up, it popped and came apart. The local electronics store should have one on the shelf in a few days. Thanks!

That is a charging resistor. Some call it a run resistor. I forgot what the diode is for.

Looks like Kevin is a little dyslexic. I think the wiring diagram is 611-1086 (or 611C1086). I think the purpose of the diode is to suppress any reverse polarity surges to protect the solid state control board.

I've been looking maybe they are referring to the diagram manual 900-0186 . You typed 900-01876. no big deal.
