Clamps unpowered until connected to battery! Dude, the sticker is right there
It took me two seconds to figure out what you just said no battery connection no power LOL
I saw a video that a guy added a toggle switch and jumped it to manual and made it power without even connecting it that was great then you could turn off the toggle and it would go back to automatic charging
I have one of these chargers. It has a problem with charging. I am a retired electronic engineer. I started reverse engineering my unit.
It is the exact same unit you have. I found out that it is a Silicon Controlled Rectifier based charging circuit thus it has no Bridge Rectifier.
That component you pointed out as being a Bridge Rectifier is actually a transformer used to provide power for the control circuit for the SCRs.
I am still working out all the details here. due to the size of the components, Surface Mounted, its difficult to identify what type and value of each.
If any body is interested in how this type of charger works you can search for SCR Based battery charger here on UA-cam.
You're a gem, thanks for posting and sharing your experience and knowledge.
I added a one 10k ohm 1/2 watt. Soldered it from the 19Vdc on top the relay to the breaker and works great. Getting 10Vdc to breaker, and still shutting down to keep battery from over charging at 14.8Vdc.
10k ohm 1/2 watt resistor.
Got any pictures ?????
What you pointed out as the bridge rectifier is the step down transformer to reduce the voltage. The rectifier is likely the two diodes diodes on the circuit board you said changed the AC to DC.
You are correct on both points. My comments in the vid were before careful inspection, both visually and with a dmm.
@@bailmox2813 How do you know when the battery is fully charged, because when I connect charger to any Battery the one LED light goes on and never turns off. and I mean the green charging LED on the charger, or do you have to rely on the meter that say's 100% to know, because the margin of error is greater relying on the meter, versus the charger turning off automatically.
You make it too complicated . You do not show close up videos so one can see what you doing
I came across this in one of the reviews for this product on the HF website: "Open the charger and observe that there are a pair of wires (black and red) that connect between both PC boards. This is the sense wire that turns the charger on when there is a battery connected. Add a PUSHBUTTON switch in parallel with these wires and mount the pushbutton type switch to the front panel." I assumed this meant he was just disconnecting the balance line, but he also talked about using another battery to get it started, so maybe this was just his way of being able to connect a 2nd battery to the charger instead of to the battery being charged. I'm going to have to go open mine up now and see what I canq do. I wonder if there is room in the case for the internals of a spare dc adapter instead of stepping down the 18v off the board.
I read that review too. I assume that he was using an older charger because no such wiring configuration will work on this charger.
You need to get yourself one of those cone shaped sheet metal bits. They work awesome for a procedure like this and your holes end up more circular too.
Step drill bits?
@@onlylettersatozornum haha yeah that's what they're called! 😂
You need to read the note on top of the charger!!! Clamps unpowered until connected to battery!! Most battery charger are made that way now days. What a goof ball, Geeeezzzzzzzzzzzzzzzz
Yah and its dumb. You can't charge a dead battery with them anymore like you used to be able to. Unless you like shelling out money to buy a new battery when all that needed to happen was it needed to be charged beyond 6 volts. He needs a constant 12 volts for Electrolysis. They no longer make them unless you shell out tons of money for one a charger like what he turned this one into. So the smart charger part is dumb.
Life saver. Trying to reverse electroplate n got this n was pissed lol
Hello Sr , I do not see the black wire connection .
best regards
saw doing it cheap do this u soder to points together and put a switch in it to make it turn off when u need it to
Could you just plug that up to a car battery and then run cables from the battery to your project
That worked for me.
Do you still need a rubber mat to stand on? I would agree that one is not necessarily used for a car jump, but how would it be on wet wood? And if they touch on the wood and arc, no worries there as well? Thanks for any and all info. Also car battery is on the table, or still in vehicle.??
@@depressionnow8290 I had a charge car battery out of the vehicle. I just basically jumped my battery charger while it was connected to electrosis setup. Worked like a charm.
The newer version of this charger has completely different circuitry inside, but I got it to work for electrolysis, resistance soldering, etc. See my lengthy comment in Part 2 of this series for the "how-to."
It would be really nice if you could just buy a "dumb" battery charger for etching and electrolysis. Everyone in their tutorials says, "get yourself a non-smart battery charger." Problem is I don't think anyone makes them. I had hoped this battery charger wasn't smart because it says "manual" on it but it's not or at least it's not dumb enough for what we want to use it for! 😂😂
Just have a look on ebay. There is plenty of old fashioned battery chargers there.
So where do we solder the switch wires to exactly? I realize he did it does not show where to solder both ends.
Can show how to wire your voltage divider, what value is your resistors you use?
Now why would one want to remove the reverse polarity protection.. Gate voltage with ( resistor ) only seen on positive side clamp to see a positive voltage on that end, 2-5 volts ish @ FET ( positive side sensed, not negative side ) then it will close loop the negative side. to begin charging.
Quick question since I didn’t see that part / Voltage divider underneath the black tape is all three wires solder together with heat shrink . One goes to ground the other one to current and the other to the 18v ??? Am doing the same thing / does it Automatically stop charging the battery or is it constant Voltage. ???
A lot of good electrical knowledge from you and your commenters, I don't quite understand it, but if the charger was new, why not take it back?
He is not wanting to charge a battery (as intended). He is going to use it for a different purpose that it was created and sold for. He wants to use it for fractal wood burning. If the safety mechanism works correctly it won’t burn the wood.
This video was really helpful actually but I ended up utilizing a different method to get the same result, as it was a slightly different charger with a seemingly more convenient way to accomplish this. But I was wondering if you had an easy way to load the power supply? I have a current clamp rated at 200Adc, and I want to make sure my unit can actually do the rated 50A. I just don't actually have anything that can take 50A@12Vdc continues.
the hack worked o the model you used they changed boards and I can't find any AC voltage except for a constant 53 dc volts I can't even see a a volt rectifier (I can identify with ) CAN U HELP??
Are there anything in the magic black tape ??? Connection? Resistors??? It is an important part, not using screwdriver to open the box waste time. Thank you.
Dam witch ones did you put togeter
the "idiot proofing" of all things has ruined it for the common man who has enough sense not to do stupid stuff, we are now stuck with rigging our equipment to work as it was designed to work...
You will need a battery for this process and experiment for this type of charger that you have
I want to use my charger like normal but I want to be able to flip a switch so the +&- have power without connected to a battery can someone please tell me how to do that on my battery charger
On the charger when he pushed the button it sounded like a relay kicked in (if that's the case the voltage sensed powers the relay) adding a toggle switch in parallel to the relay contacts would bypass the relay giving you your desired result.
@@TopCat2021 just now saw this comment would you be able to show me exactly what I needed to do or just help me find out what I need to do
Why aren't we using electric screwdrivers why just a plain old screwdriver takes forever to open this thing just saying
I'm triggered just looking at that fucking box
You need to read the note on top of the charger!!! Clamps unpowered until connected to battery!!
so, all of those changes are not necessaries, aren´t they?
Even if you hook them to a battery they have no guarantee of powering to 12 volts. Smart chargers are not that smart they only work if the battery still has above 5 to 6 volts or they stay powered off anyway. All he did was turned this charger with a toggle switch into a old style charger which has become rare and hard to find. Unless you like paying for batteries when nothing is wrong with them. And to do Electrolysis you need to have a Constant 12volts. Read his description.
He knew that, this video explains how to bypass this bullcrap so it can be used as a 12 volt power supply.
It's doubled in price at $60.
$30 this month. Sometimes they take the additional 20% discount coupon also.
Did u make part 2 I would like to know ur resistor values u used
I used 220k ohm 1 watt resistors. The actual resistance values shouldn't matter as long as you use two of the same values, ie, two 1k ohm resistors would have given us exactly the same voltage to the sense wire. Part 2 should be up in just a few minutes.
Harbor freight sells step bits lol
Really?
I dont get it. He found output at 18v and put it through a voltage devider with equal resisters. should that half the voltage to 9v?. So were does the 12.6v come from?
You are using 1w resisters. How is that enough for 10 amps?
What size resistors are you using and how are they wired?
Sorry to be so offtopic but does someone know a method to get back into an instagram account?
I was stupid lost my account password. I would love any help you can offer me.
@Juan Watson Instablaster :)
@Cairo Cory i really appreciate your reply. I got to the site thru google and I'm waiting for the hacking stuff atm.
Seems to take quite some time so I will reply here later when my account password hopefully is recovered.
@Cairo Cory It did the trick and I finally got access to my account again. I'm so happy!
Thanks so much, you saved my ass !
@Juan Watson glad I could help :)
You should not do this to a battery charger. You just bought from Arbor freight. You should leave it like it is and get a battery andtestive more or less. This charger also lets you know whether the battery has power in it or not. Because it has a sensor intelligent breaker on it or should I say intelligent sensor breaker on it to protect you from electrical shock or battery explosion? Please handle with care when using this battery charger.
Stupid thing to do tearing apart that battery charger especially if it's brand new you don't know what you are doing.
Maybe 20 30 volts DC current
Why are they doing this?? This is the second video I've seen about this. Are they trying to stop people from doing electrolysis. This makes me want to break the law even more. Hey but anyway bro, if you're good with electronics then the money's in modding Xboxes and game consoles. You can make a lot of money doing that. You should look into it you seem very competent. Just be observation
These chargers won't power the leads until it senses a battery being connected. In this case, no voltage being sensed by the charger means the charger won't power up. Also, it means if you're trying to charge a very dead battery, it won't kick on, which is annoying as fuck.
they are trying to stop from getting sued by stupid people.. its a safety device. what they should do is provide the bypass from the factory.
You never showed us where or how you did your wiring, nor did you show the two little what ever they are that you attached in the wiring. You were more excited to show your sparky sparks than anything......just saying.... Waisted 20 mins of my time...
Please dear god I'm begging yall dont do this it is extremely dangerous and has killed over thirty people already, I promise it's not worth it. Stay safe
😂😂😂😂
