Hi everyone I have a multimeter model: BS1901W that no longer works it has a very strong yellow fuse that has no designation so I wonder if you can help me know what value it has. Here are some pictures

Yellow PTC? Shouldn't affect power up of the meter...Comment

Re: Help Identify this Fuse
It doesn't have any fuses, only a yellow PTC to protect the 200mA current range.Comment

Re: Help Identify this Fuse
no, the yellow thing is a polyfuse.
tell me what's printed on it.
the meter looks like a Centec btw - worth about €3 if you break it.

Re: Help Identify this Fuse
hello all there is nothing printed on it-i tested but no continuity
i will try to have a better pic later todayComment

Re: Help Identify this Fuse
when you say the meter doesnt work - be specific.
does the display show anything?
does it read volts?
amps?
continuity?
all these modes use different circuitsComment

Re: Help Identify this Fuse
oh yes there is something on it LBV160 and fuse on the bcb.not working att allComment

Re: Help Identify this Fuse
Post a picture of the part that is the "fuse LBV160". Without the bblluuurrr.
It seems to be a custom British Standard multimeter made by Caltek HK.
I call a polyfuse a PTC, the big yellow squarish one looks to be for 200mA current range.
I still say there's no fuse- "self-recovery fuse protection" in the marketing. You would think any fuse would be replaceable, not soldered in for a multimeter.
There are three bead style PTC's, and a MOV - but I can't see any fuse.Comment

Re: Help Identify this Fuse
found it.
it wont stop the meter working, it will just mess up the current readings usuallyLast edited by stj; 02-20-2021, 02:25 PM.Comment

hello redwire in terms of better pictures I use my mobile because I do not have better right nowComment

Re: Help Identify this Fuse
hi stj you are right after replacing better battery now it works but not as it should i have to test some more to understand.so that fuse it does not stop the multimeterComment

Hi everyone:
This is the second time I have my sister's mixer on the bench. First time I identified a blown tiristor......this time I guess it's the thermal fuse (reads open).
My understanding is that it should be (NC) normally closed and open at 85C?????
Could you help me to identify/get a good one? How many amps? I was about to buy a NC 10A, 85 celcius in Aliexpress. (ceramic one)......but I guess is too much.
Wording in the back......... "limitor 16", "T160".
Thanks in advance,
Francesc.... -
Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping... -
Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the... -
Hi guys,
I'm inexperienced with electronics repairs, I've done a little bit of soldering caps and whatnot, but i have a blown fuse on this mimaki printer I got which I have bought a replacement for.
How do I remove this type of fuse (see picture)...it kinda looks like it would pull out of that bracket but it didn't come at first pull and I didn't want to brute force it incase it's soldered on there like most of the rest of the components.
Anybody know how to remove this type of fuse?
(The fuse is toward the bottom of the image labeled F2)... -
I found a project in the electronics trash yesterday. A nice Argon SA1 audio amp with some electrical issue. Took it apart and saw that the 4A250V fuse was blown so started lifting components to find the short. Eventually got to two MOSFETs (model FTA14N50C) that are shorted and when i took them out the short was gone.
Now i didn't have any replacements of the same model of course but i found a couple with pretty similar spec i thought (K10A60D & K12A50D) and put them in. Also replaced the blown fuse with a 3.5A250V one. Checked another time for short circuit and plugged it in....
