Triplight UPS Issue
larrybl:
I'll open it up tomorrow, but 99% sure I won't find the problem.

Just replace the small electrolytic capcitors, there's probably a switchmode power supply IC and there will be some capacitors associated with that. You can also look around for cracked solder joints, particularly on the relays.
larrybl:
Not seeing anything out of sorts. I can buy a new 400va ups for less than $50.00 US, which most likely would be less than trying to locate the issue and fix this.
james_s:
I see several capacitors that I would suspect, but a visual inspection is completely useless in most cases, they have to get *really* bad before showing any visible signs of problems. You need a ESR meter or a can of freeze spray/air duster can be useful. If you don't feel like trying to troubleshoot it though just replace it, they are cheap and easy to find.
