never had one of these, that's a capacitor, right? also don't know what capacitance this is, tried searching but came up short
edit: OK, since it's 1000V I guess this isn't electronics, askelectrics doesn't exist yet?

(dogdammit lemmy, can't you tell me what image size isn't too large, I hafta guess?!)
The fact that a capacitor is marked with a 1000V label does not necessarily mean that 1000V are present on its terminal (but you should use caution). I don't think the voltage makes it out of the realm of electronics.
It's quite hard to answer your question, as the board is quite dirty and you provided a single picture. You could check for continuity and capacitance value with a multimeter
