This UPS died unexpectedly. Replaced the battery and no charging at all. hmm I found that strange, these units usually last longer than a couple years....Once I cracked open the unit I searched and searched for a bad component and found NONE! I went back to basics and traced the power from the input as far as I could. Turns out this unit has a FUSE hidden under the transformer. I am attaching a pic that shows where. I ran a new fuse with a couple short leads so I would not need to unsolder that transformer again! Thought I'd share my experience and save others the trouble for this kind of repair. I also cam across the service manual for this series of UPS. I am attaching that as well.
