Hi,
Back after a long hiatus with some old power supplies that need repairing. I've recently picked up a couple of 386SX systems, two 486DX systems, a SiliconGraphics Indy and an iMac G3 that either have verified leaking capacitors in their power supplies, or are likely to in the near future. For the sake of simplicity, instead of tackling all at once, I'm starting with the 386's and one of the 486's.
The 386's power supplies are Seasonic SS4040A's, with caps that are visibly leaking, and 9 replacement caps per unit are required. Most appear to be from the Rubycon... -
UPS turned off one night and it seemed that the 3 year old batteries gave out.
Replaced with a new pair, but the UPS software claimed the battery voltage was only 18 volts and needed to charge. After 24 hours, the UPS claimed only 60% charge and 20 volts (although FWIW, my meter sees 27v).
...then I found various Cyberpower threads here with some guidance on what to check.
C1 (22uF) tested at 2, so I replaced that.
Put it all back together and didn't see a change on the reported battery voltage. Although, I did run the quick battery diagnostic... -
I got lucky that when I got home and was about to get some ice out of the ice dispenser I hear and see water running down the outside of the ice dispenser what the heck is going on here

Well I put the new one in and wait and I wait for the water valve to open and let water in no such luck well there is a way to check the function of the motor and the water valve on this ice maker just need a jumper wire “L” to... -
I'd like to start out by thanking this forum for providing the info to be able to repair my 15 year old CP1500AVRLCD UPS. Here is all the info I gathered during my trouble-shooting and re-capping.
Like clockwork, I've had to replace the SLA batteries every 4 years. It was about that time and the UPS was acting like it needed new batteries... randomly shutting off with AC present, not being able to charge fully, and poor runtime when AC was removed. So, I replaced the batteries but noticed that it was not charging properly.
I decided to verify that the batteries were... -
I had this refrigerator at my old folks which I noticed I would put my beer or soda in and take it out warmer than I'd brought it from the store.
Now, I don't know much about refrigerators or HVAC but to me it seemed like we have a problem. I threw a thermometer in... 20 deg C in the fridge. WHAT THE...
Freezer worked fine with temperatures way below zero, as it should, and it has only one compressor for both sides so it got me scratching my head for a while.
Only other things that seemed a bit odd was that the heatsink on the back was barely warm and the...
