Re: APC Back-ups RS 1500 Dead

I just replace c40 & c41 & to my amazement it fixed the problem. Mine suddenly went to battery the other night even though it had ac power, and to think I have thrown at least 2 of this same model away over the last 2 years or so, wish I had know this sooner. FYI the cap installed in the above picture for c40 is backwards, (surprised no fireworks or blown) the polarity on the board is correct (the black edge on the old smt cap is negative)
