Require circuit diagram for charger 5100235-08

Only seriously demented ideas available here. You have been given due warning as I have no idea if ANY of them are of the least value or if they might cause the charger to explode or fry you. 1) Here is a parts lists for chargers: https://www.centurytool.net/Associated_Battery_Charger_Parts_Listing_By_Model_s/27.htm

2) Simple 48V automatic battery charger circuit https://www.homemade-circuits.com/make-this-48v-automatic-battery-charger/)

3) https://www.google.com/search?tbm=isch&q=INC-4825+charger+circuit+diagram&fir=2h2vwjvWk8DcyM%252C0q8ujlS5HC-1tM%252C_%253BHPQ3OEJawOeocM%252CyiLgDIxQYa_G0M%252C_%253BW1oSQRy1Y0A37M%252C0q8ujlS5HC-1tM%252C_%253Bz5qM7XOpqWeYuM%252C0q8ujlS5HC-1tM%252C_%253B4d_LJ6uToWkhAM%252CH3oT2sNG5HcqkM%252C_%253BYDHG5Cm1AL6O3M%252Ce3JndQzU7tP_AM%252C_%253B5BVOX4JophqPOM%252C0q8ujlS5HC-1tM%252C_%253Btg4vpyM4brHVIM%252C0q8ujlS5HC-1tM%252C_%253BT4Q7wJ3ia86DaM%252C96ffaPQ13bEASM%252C_%253BMYk-of_VBir31M%252CgunQ_JLWUteTFM%252C_

4) Get an extra charger and take it apart. Maybe you can identify something in it with a magnifying glass.

5) Aren't these things patented? Of course it might cost an arm and a leg to pursue that as a means to get a diagram.

Feel free to resume rolling over in the floor laughing at these ideas. Perhaps you should have restricted the query to GOOD ideas. If any are accidentally useful, put that in a comment.

Why?
Chargers are so cheap that it is not worthwhile & even unsafe to repair. Just buy a new one.
If you still want to repair, you really do not need a circuit diagram. Just replace swollen (bulging) capacitors and resolder the output cable. Cable is usually broken at the "bending point".

black&decker dont have diagram for charger,only sell new one
i dont know this one but i can tell you,most of the time it is hard to find the problem on black charger.do you have a picture of board?

Recheck your phone with another charger which is amply available in the friends circle, once confirmed the charger can be replaced. There are cases in which the circuit functions improperly , sometimes the capacitor can be replaced to rectify the faulty.
other wise as these needs to be broken open the charger can be replaced.
If your charger test also give the same result, then the battery or the charging circuit in the phone is faulty.

You can contact a Dewalt Service Center to see if they have the diagram. Black and Decker is Dewalts lower priced line. A quick search on their website did not reveal anything. They may not have the diagram. As far as I know there are no parts available for the chargers so you may have a hard time locating the diagram. Try giving Dewalt a call.

My charger (24 v) died also and repair shop wanted too many $ for repair. I happened on-to a charger for a printer (24v 1 amp) at the thrift store for $3.00 and fashioned a connector for connecting to the battery. It takes about 3 hrs to charge the battery but you must disconnect manually. It has been working for many months. It will do for me untill i find a bargan on ebay. The repair shop said that the part that failed was not a component that can be changed. (Multyfunction chip) Hope this helps for the short term. Enjoy

Hi,I just find the circuit diagram,hopefully that could help you ! :-)
