I've searched high and low for a charger troubleshoot video. There are none!!! Then i found this one. Thanks for taking the time to tear this down and recording it. I'm oldschool and want to know why my kobalt charger is acting crazy and not charging. It's $60 for a new charger! Rediculas! I took mine apart after watching your video and guess what! Yep i found it. Same thing was wrong with mine. I'm going for it!

[@dariusz879]

Hello. Our conservation volunteer group had two of these chargers with the same fault. Your video has saved us about £100 on replacing them. Many thanks!!

[@Fentertainment]

Glad it helped

[@johnlloyd2534]

Thanks brother!!! You saved me a 60 minute round trip ride and prolly $50 or more... so simple and took less than 10 minutes. Thanks again!! John, A1

This is one if the best instructional videos I've ever watched. You have a really good talent for teaching. Thank you for this information. 💪

[@jeffharris4312]

Thanks for posting this!!! My Dewalt charger was having the exact same problem. Opened it up and found one of the capacitor leads had not been soldered in properly and had come loose. I re-soldered it and it works perfectly now! Thanks for saving me some $$$!

[@danieltaylor8347]

Perfect. I had a charger quit on me, and I suspect the same issue. I'll get back with you when I get it repaired. Thank you for showing me how.

[@Angryoldman50]

I found a DCB107 in the trash. Plugged it in. Nothing. So , here i am on yt looking for possible issues. From the comments, I would say it's the same issue. Thank you for posting this 5 years ago.

[@rogerpianoking1945]

I’ve just repaired my dead charger. Having worked in the electronics industry for 40 years, I found that 2 diodes on the bridge rectifier had gone short circuit and blown the input 2A fuse. I requested some diodes from a mate at my ex work place,1N4007 and replaced. These have a good reverse voltage breakdown 700V. I replaced the input fuse with a direct short as the mains fuse plug is rated at 3A so that will protect the circuit. I suspect a surge on the mains supply caused the problem. I’ve recharged both batteries and my drill is now up and running.

[@butler386]

Great video. I think I have a couple of lithium battery chargers so this came in very handy just in case. You did a great job of showing how to diagnose and fix the charger. Good job.

[@moefuggerr2970]

I am a repairman. That is very common with any power supply. Good vid.

[@djsi38t]

Freakin Brilliant.Such a simple fix that most would skip and just throw away and then shell out like 80 bucks for a fancy new charger.I have seen plenty of bulging caps on motherboards that still worked fine,so I dont think I would have thought of that.Since it was the only thing that looked off,great call on replacing that part.

[@Fentertainment]

We live in a throw it away world. Before I throw away anything I usually take it apart or see if I can fix it. You sound the same.

[@jafypacu346]

I have had the same problem with my DeWalt DCB107 charger here is Zambia where I relocated from the USA about 3 years ago now. Thanks for sharing your detailed fix for the problem. Now I just need to see whether or not I'll be able to source the capacitor locally.

[@emmettturner9452]

If you are in DeWALT’s 20V Max system it’s hard not to end up with several of those DCB107 chargers. They only get away with charging so much for replacements because contractors make mistakes (leave them) and will overpay for an emergency charger to avoid holding up a job. I, myself, have four DCB107 and one DCB118 fast charger. First one came with my brushless drill/driver set. Turns out my mom had already purchased a brushed drill with the same charger before moving in with me, bringing a second DCB107 into our garage. Next, I got a PowerDetect hammer drill to anchor into concrete which is how I ended up with my DCB118 fast charger. Finally, I bought an open box DeWALT mower that included two more of the DCB107 chargers for a total of four plus the fast charger. I’m here because I’m considering mounting the extras into a TSTAK box so that the attached batteries don’t roll around and I’ll always have chargers when on the go.

[@gera19871068]

Great Video, I had the same problem with the charger,but thanks to this Video i was able to reapair it. Thank you!

[@billwessels207]

Thanks a bunch. Same problem, same reason, same solution. Took mine apart, same bulged capacitor. Great video, Sir.

[@Fentertainment]

Awesome!

[@ebastelli]

Thanks for the Video, it encouraged me to open up my charger and check for a swollen Cap but it was ok, So I looked around for another issue and found that under a diode was dark brown like from excessive heat (i think it was number 201 on the board) so I turned the board over and saw a cold soldered joint on the diode and re soldered it and Voila It worked!! Thanks Again

[@Fentertainment]

Thats awesome. Most would've thrown it away.

[@groovejet33]

That's great. I wish I was that lucky. My 12v charger is fast blinking . I'm sure battery is fine. Looked at board and can't see any visual issues. Last week the charger worked one time, and battery was fully charged. But goes to fast blink again.

[@kennetheady1347]

Thank you sir. You explained it very well and your demonstration gets five stars from me.

[@MLFranklin]

Dude, I've been having the exact same experiences -- this happened right around the time of one of our California Public Safety Power Shutoffs. I even went back to my old super-reliable DeWalt 18v drill. I actually bought a couple of new 20v batteries and ordered a new charger. But now seeing this, I'll have to try this trick. Thanks and please keep up the great work. I'll let you know if it works.

[@Fentertainment]

Please do!

[@georgeokafor2722]

My own got burnt this morning so it produces awful smell could it the the capacitor or the transformer though I haven't opened it yet

[@kia0016]

Great video. Had same problem, capacitor was $6 on Amazon though, but 20 min fix and works like new. End of the capacitor was extruded and appeared like it had expanded 1-2mm. So I soldered in a new one and, just as this video shows, it worked like a charm. Thanks!

[@allen1473]

I’m having trouble finding the capacitor on Amazon. Followed the link and says product unavailable. Any suggestions on where to find the correct one? I’m unsure of exactly what to look for.

[@kia0016]

@@allen1473 Open your charger up, make sure you see 68 and 200V, in case your model uses different capacitor. I don't want to order from China, so I bought the one in the link below and received in 2 days locally. Make sure solder iron gets hot to remove the old solder, I used solder wick to suck up the old solder, slightly applied tension to old capacitor so the moment solder melted, the leg pulled out. 20 min fix!, and my old capacitor had a slight bulge, so moment I changed it, I was back to normal charging. Now run my charger on a power strip/surge protector.

[@rpennybrown]

Very helpful video. Side note: one of our DeWalt chargers had a 100-micro-F (200v) capacitor and the other one had a 220-micro-F (200v) capacitor. So not every charger will have the 68-micro-F (200v) one shown here I guess. The 100-200v charger repair was successful, but our replacement of the capacitor on the 220-200V model failed.

[@martyhameline9685]

[@calholli]

That pin coming off of your connector will probably be an issue in the future.. At 4:23 . you can see that green pin on the board at the bottom.. where it's coming out of your connector and mounting to the board on the right side pin. I would desolder that and clean it up and add some new solder; to get rid of that green corrosion. It probably dripped some water down in there and is starting to corrode away and might short to the pin next to it, etc.

[@krish7893]

Great video and thank you for sharing. I wonder how many Dewalt chargers have been "bought" after people getting stuck with no choice. Also, think these chargers are made to self-destruct overtime to ensure repeat sales...

[@Fentertainment]

I agree. Said the same thing!

[@jtsongas]

Since you had it open, it probably would have been a good idea to clean up J1 and J2 on the board as it looks like there is some corrosion. Looks to be on the main board as well as on the little board which contains the actual terminals the the battery contacts with (not as clear video so hard to be sure).

[@MrsBuddevil]

I have a hole blown through I guess it's called a resistor. Do you have a link for replacement part?

[@RaudelJaureguiJr]

I have the fast charger model and the torx T15 bits are too small, and the next up, the T20 are too. Can't figure out how to remove the screws 😭

[@muraveera]

I had the same issue... remember it is a security Torx T15 and not regular T15. Torx security screws have a post in the center of the head that prevents a standard Torx driver (or a straight screwdriver) from being inserted. I was able to shear the center post using a tiny strong flat screw driver and then my regular T15 just had a snug fit.

Can you do a video on repairing the audio output side of a car stereo amplifier ? I’m not gonna lie, I have pushed this 4 channel 3000 watt amplifier to its max for year’s from car shows and tailgate parties to crank it up stereo competitions. But the funny thing is it stopped putting out audio on a 2 hour road trip after it playing at maybe 15% power. Just turned up loud enough to where you can talk to the passenger without yelling. I have took the case apart and looked for blown capacitor’s or anything obvious but I got nothing.

That is the mains buffering filter capacitor. You can put in a higher voltage rated one about 120 to 400uF at 400uf would make the problem go away for good. 🤓😊😁

120 to 400uf at up to 400v. Fix it for good.❤

I have the same problem with two of my old DCB201 batteries. If I didn't have to order the t15 torx security screwdriver set, the soldering iron, and the capacitors I would probably try to fix it, but I can just get a new charger on Amazon for the same price on sale or less (found one for $38) without all the hassle. This charger still charges my DCB203 battery, but if I can salvage these two DCB201's, it's worth buying the new charger. HOWEVER... if I think I'm going to use a soldering iron, capacitors, and a torx security screwdriver set again... it might be worth the investment?? 😂
