Philip: Pretty sure that is a hole in the cap, and also the bottom seems to be split open right at the edge, below the hole. Craig: yes, planning to replace ALL THE CAPS (or my Pistons will MELT!)

Re: [MBZ] ***SPAM*** RE: OT CyberPower UPS won't charge batteries
Yes - most of the bad electrolytic caps I've seen blow their tops, except the large 400 volt in my transmitter power supply back in the days when they glowed in the dark. I fed it 450 volts, it lasted probably 20 hours, then blew it's bottom out - very smoky and stinky. I replaced it with a 500 volt cap.

Oh, yeah! I thought the ATC fuses were caps, but now that you mention it, the strange looking characters (if you read them top to bottom) are actually "40" if you look from the side! :-) Craig ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

I do see your one picture and four comments. I think the "splooge" to which Curt refers is not glue but melted capacitor guts. You should replace ***ALL*** of the electrolytic capacitors (EVERY SINGLE ONE!!!). You can lift one end of the questionable resistor and measure its resistance and replace it if it is out of tolerance, or just replace it.

Are there two blown caps? What about the sploogy one on the left of the picture?

Re: [MBZ] ***SPAM*** RE: OT CyberPower UPS won't charge batteries
Thanks Greg! Sure 'nough, blown cap, very obvious. Reading about another CyberPower UPS with similar "no charge" failure, apparently the factory used some type of glue that degrades with time and becomes conductive, and that glue is used in several places on the board, including at the base of this capacitor. The glue has turned from yellow to dark brown (carbonized?). Looks like I need to clean off that glue from all over the board, then replace all the electrolytic caps, maybe other components that are bad, and then button her up and let her rip. Pix to come soon... - Max Charleston SC On Fri, Sep 6, 2019 at 4:44 PM Greg Fiorentino via Mercedes < mercedes@okiebenz.com> wrote: > That earns you an Attaboy! > > > ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
