It's a 4700uf 35v electrolytic AC filter cap. Reads fine on the capacitance meter, but when I check resistance for short/open, it reads as a dead short for about 3 seconds, then slowly raises to about 147k ohms. I know it's supposed to start low and go high, but is it ever supposed to read as a dead short even if only for a few secs?
I thought buying a cap meter would help but from what I've read on the net, bad caps can test good and the only way to know for sure is with an ESR meter. Any advice?
Thanks!
