I have a capacitor from a fan. The electrician says it's dead, but I think he is lying. I want to test it with a multimeter. But I can't identify which terminal is positive or negative as it's old and from local company. A poor video of the capacitor is below: A few pics from the video: A sign on the bottom: company logo or identifier? I came to kmow from a site that a fan capacitor used for starting the motor is unpolarised. Is that correct? If so, then I don't have to think of positive or negative terminals while testing, right? If not, please help in identification. Note the sign it has at its bottom: is that a company logo or an identifier? I want to give the capacitor a death certificate, and I don't need to calculate the capacitance. I only want to see if it's OK. The electrician has charged quite a lot, and I want to see if he was telling the truth. N.B.: The video quality might not be very good. It has no sound except background noise. I used it to show the capacitor from all sides. Pics are from video which I uploaded, so the play and pause buttons have also come in the screenshot.
