KJay, thanks for the post. I went to the site you posted and seen the tester you was talking about. Although I didn't get that one, I seen another one that was cheaper and had all good reviews on it, so I decided to get that one. It is a "Newcason" testing from 20MF to 200pf. It had 9 reviews from HVAC persons. I started to get another cheap one, but this one looked better. I got it for $ 20.99. from Amazon. Hope it works right. Got interested in one when my son's a/c went out, and had a HVAC friend come by and check it. The capacitor was bad. I may not be able to go very far in the HVAC trade, but at least I maybe able to change a capacitor out if needed.
