The fan ticks or makes something when you short ps on with ground or just dead?

that's normal condition, by pulling the signal down the supervisor starts the main power supplyLeave a comment:

Re: Cougar CMX 700W suddenly Went off
Alright i have checked again, how ever i am sure that all gives 0 voltages except the 5VSB
something new happened now, maybe the cleaning did something ?
the Green Wire voltage = 2.973 V
when i try to force power on while measuring the green wire voltage it jumps to 0 voltageLeave a comment:

Re: Cougar CMX 700W suddenly Went off
So when you keep the PWR On high, do you have 3.3 V or not?
Lightbulbs are bad idea unless combined with NTC in series. Startup current of lightbulb is hundreds of amperes, that can kill rectifier right away.Last edited by Behemot; 01-18-2017, 03:13 PM.Leave a comment:

Re: Cougar CMX 700W suddenly Went off
Have you tried it with a car bulb or something that can put some load, some PSU don't like to start with no load.
Check d 10 out of the unit, took every glue that looks brown. The fan ticks or makes something when you short ps on with ground or just dead?
When it went of did it make any wierd sound?

OK. I got the rocker switch figured out thanks to the good advice on this forum.
Now I need to figure out the correct wire to go to the switch from the broiler element and from the oven element.
This is a Whirlpool RDE3340 electric range.
The common wire on the switch appears to have a high temperature insulating material. I am guessing that both the wire to the broiler and the wire to the oven elements also need relatively high temperature insulation. What do I need to look for? The broiler is rated at about 2400 watts.
Where may I find parts... -
We have an Lenovo Yoga 710 15ISK that we use as a secondary laptop. To cut a long story short, around May 2023, while traveling, I connected the laptop into an electrical outlet that was already switched on. Something made a "pfft" sound and the laptop refused to turn on after that. After getting back home, I gave the the laptop for repair to an informal repair person. He replaced the adapter and an internal motherboard part, but after he returned it I noticed that the LCD did not look normal. Essentially, every alternate horizontal line on the screen had gone missing. The laptop was... -
I currently have a customer's vintage fan on the work bench to repair.
It uses an induction motor with 4 poles. One of the poles is open.
I couldn't find the break so i cut off the original wire.
I have measured the other poles and the resistance is about 28 ohms per pole and I measured the diameter of the wire with my digital calipers and it is 0.35mm in diameter.
I need to work out how much 0.35mm diameter enamelled copper wire i need to order for it to be 28 ohms. I have used this calculator and it says i need 160.35 metres.
The enamelled copper... -
I was Ollie today which is a close out / surplus outlet store I do not go in there to often because you find things that you should not be tempted by but that is a another story
I saw a small space heater that used a wire type of heater element which I been looking for a while but not really hard mind you but when I saw this I grabbed it I going to go back tomorrow and buy the last one that is like the one I bought today because I need the heater element and the ceramic insulators and more of heat element wire because this one has two different wattage settings one 1300 watts ( tap... -
I got this recently as-is. Gigabyte 1070 video card.
DVI port is removed. I don't know why.
A wire is soldered across two spots where it looks like the DVI port was. I don't know why.
I've read of people simply ripping out DVI ports and the rest of the cards still working fine. Never read anything about soldering a wire in there for some reason.
The card seems to work fine, except it's stuck in low clock speeds. While starting a game or benchmarking, the clocks may momentarily increase to around where they should be, then goes way back down and stays...
