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
