Powermate UPS bad electrolytics?
I have a Powermate 9120 UPS. After replacing the batteries, it came up
with "DC bus fault"
My first guess was that the batteries were not connected properly,
or maybe a relay had burnt out.
Then I found in a Finnish forum that this fault was cured by replacing
two capacitors. The poster further claimed that this was a frequent
failure in these models.
Has anybody fixed this brand of UPS and found bad caps are the culprit?
