I have got a capacitor from a fan. The electrician says that it's not working, but I think he is lying. I want to test it with a multimeter. But I cannot understand which plates are positive or negative, because nothing is marked. These are a few pics of the capacitor:
It has no marks on its body to indicate the positive and negative terminals. It only has one on the bottom, which I believe might be a company logo:
How will I understand which is positive and which negative, so that I can use the multimeter probes correctly?

N.B.: pics are from a video which I wanted to upload, so the play and pause buttons have also come in the screenshot.

That capacitor is not polarized. There is no positive and negative lead. You can connect it either way.
