gear surface damage due to electrical discharge?
(OP)
I am looking at a gear with a damage that resembles that of electicral pitting due to arc discharging. Is there anyone who has seen this before? I have seen it, but in bearing. The appearance is very similar, which makes me thinks this is electrical to.
