- You can learn in this short video How to fix Apc Ups overload error any other model.Its cheap and simple but u have to be carefull.You can find the schematic for model in this video in this link:

Thanks for the informative video Marius - Old electrolytic capacitors are by far the most common components to fail (in my experience) and always worth checking first, which can save considerable time spent on diagnostics. I found that when the UPS battery's approach their end of serviceability, they put considerable additional strain on the battery charging circuit. It pays to install new batteries at the recommended intervals, which few people do. Most components will typically last decades, except for those filled with electrolytes. 😉
You are perefctly right bro.
I like your video (the problem is well known but your video is very steady and focusing. Thank you!
tnx man for feedback.for the moment i am using my phone,but when I will receive money from YT I will buy better camera.
Wow, this is great thanks! I see you just posted it 7 days ago and I was looking at the same issue on my APC Backup-UPS XS 1000. It is similar style on the outside so sure it is a similar board. I will open it up and take a closer look. With the original battery in it, it was just making beeping noise and lit "On Battery" but then I changed it to another BAD battery I had (showed on other system "bad battery" and using those batterys it actually lit up Overload. So if the batteries are really old or haven't used in a while it might not even show the correct error. I will buy a new set of batteries for the unit I know that works and then test those in the unit I am not sure if it works and then if I get that overload message again will follow our video or have someone do it for me with better soldering skills
I had to remake this video because of copyright.original had 15K views and lot of coments.I hope u will be lucky and solve problem.
Helpful video. Thank you! A friend asked me to look into a APC Smart UPS 750 which was clicking endlessly when plugged in. I took it apart, stayed that way for a while, and after I assembled it back, it worked as it should. The batteries charged to 100 percent, but this overload issue started right when I plugged in a 300W laser printer so test the UPS further. The screen showed over 120% load and it beeped. No idea where to go from there.
replace this capacitor.maybe u r lucky.
Curious how/where can you find the schematics for the various models, especially the SM* series? Looking to find out how to manually run "self-test" and possibly run tests through a serial connection.
I did some tests long time ago with special cable to conect to the pc and dedicated apc program.but i dont remember the details sorry.
@@diymariuselectro Thanks. I recently bought the NMC APC9641 as I found it on Amazon/APC store for a very reasonable price considering a used 9630 or new 9640. The NMC will can run a self-test manually in addition to other tests. There may be a way to run it through the front panel as well.
great information thank you very much
tnx bro hope we create toghether a strong comunity.
Good explanation.
tnx hope that helps u to repair.
Hi,
please tell me, what is the purpose of the third connector inside the battery compartment? Am I correct in understanding that two positive and one common negative wire come from a pair of batteries?
now I dont remember,cos was long time ago. I think its some kind of feedback.
My APC 500 backup enters in OVERLOAD alarm even without load. Thanks for your video.
tnx bro
Good morning,
Thans for your good vidéo of this problem !!
Can you help me ?
My C60 positive solder point on the motherboard is damaged.
Can I get this point somewhere else?
Thanks !
find the schematics for your model and foolow the wires.its simple.
When I start playing the overload alarm starts going off, is it normal? or do I have to change the 22uF 16V capacitor? I have the apc ups cs 500 model
yes try this maybe u r lucky.
How to check gate drive of this ups, sir in my apc smart 1500 ups gate drive of +ve chennel is missing results no output how to repair this problem please help me.
you need schematic and osciloscop and check step by step.but if there is a big fault,is cheaper to buy another ups than repair it.you can repair only if you want to learn electronics,
Sir I am already expert in repairing of inverters that is the resason that I have checked its gate drive, i have also changed it's ic18(H-driver) smd ic, i found there is no input signal at pin no 2 & 7, Also I found voltage is at pin 3 & 4 that goes out from it's pin 13 & 14 also at pin 10 & 15 that drive voltage is absent. I think it's ic21(361-0025v2) is perhaps faulty because there is no any voltage at pin 4 & 7 of this ic which goes to pin no 2 & 7 of ic18(H-driver)
Can you help me please, I have the same ups and it's not charging the online LED power on and off continuously
how can I help u bro? u need schematic and error codes.
What model of oscilloscope do you have?
u can find model and review on my page.in a video.
Please send me this 800 va APC UPS circuit diagram.
Sir my apc UPS AC working okay but I did new battery connection. but not working. only relay working so please sir tlk me my UPS repair tricks
sir not enough details.sorry.
Can the alarm beep be turned off? It scares my dog a lot!
at old models u need software and cable,newer models have button for sound on/off.or u can take out the buzzer :)
Thank you! I removed the buzzer.@@diymariuselectro
Thank you for your informative video please send me total circuit diagram RS 1500 and explain.
I dont have it but you can find it on the net.
@@diymariuselectroThank you
Find many time but not
