Photo here shows the fuse that is broken in my battery charger. I dropped the charger and it quit working so it looks like this is the problem. Does a fuse like this come out of the end caps that are soldered to the PCB or is the fuse itself part of the two legs soldered to the PCB? It does not seem to be a fuse I can dislodge from the caps.

Second question........Is this fuse something that is easy to find a replacement for? Any ideas for where I might start looking for one on line?

Thanks.......wayne

Hey Wayne? What country are you from? The reason I ask is that Chinese battery chargers seem to come with 250v fuses instead of 125v fuses that would work in the USA.

That fuse that is broken is easy to find. eBay or a lot of other places. Replacing it depends on your soldering abilities. Look at the end-caps of the fuse to see what the real values of it were and replace it with an applicable fuse.

Step 1 is un-soldering the fuse holders from the underside of the pcb.
Step 2 try to un-solder the broken fuse parts from the holder caps. If you can great, save the caps for the new fuse, if not don't worry about it.
Step 3 using an applicable fuse, re-solder it into the fuse caps and then re-solder the end cap leads into the pcb....or
If you can not save the caps from the old fuse, cut the leads off a resistor (make sure the leads are the same size of the original leads)
quickly solder them to the ends of the fuse and then solder the leads to the pcb.

:D
 
Did you ever find a fuse because looks like I need one too. Just a regular 110 v fuse ??
 
Yeah I accidentally put the charger to the output of the battery and the pop. Hopefully its just the fuse here.

Ouch.... :(

Looks like you also popped a cap. A couple of things.....



Also, please start a new thread with the specific info about your charger. Manufacture and model would help a lot. The pictures are great, the better to help us help you with.

But it looks like you need to replace that capacitor for sure. :(

:D

i bot a box of 100 for $7 free shipping. already used almost a dozen.

@waynebergman , looks like dnmun has what you need. PM him, (if you haven't all ready) and see if he can help you.

:D
 
Thanks ebeach, I have what I need now from a local supplier so all is well.
 
Wow I just saw the white goo coming out of capacitor. So I can just detach both the fuse and capacitor from bottom of board via solder and put new replacements in?
 
Any dangers to myself or the board attempting to do so. Don't want to electrocute myself lol

is the goo a solid like epoxy or is it liquid? the cap doesn't look like it split on top where it has the cut lines.
