Fixing a Charger for a Cordless Vacuum Cleaner The charger for a cordless vacuum cleaner is broken. There is no DC output on the connector from the charger: ![](/upload/album/52/59/f6/b3480e0a8383VCgzwoyy.jpg)
Use two pin adapters (below, left, red and black) for the multimeter probes (below, right): ![](/upload/album/52/59/f6/b3480e0a6640W8yWE33R.jpg)
Measured DC output from the wires of the charger (power supply ) side, is OK: ![](/upload/album/52/59/f6/b3480e0a7446zV4uEgZl.jpg)
Measured the DC output on wires from the terminal side on the vacuum cleaner, is also OK: ![](/upload/album/52/59/f6/b3480e0a7739hw7Q5WBq.jpg)
Measured DC voltate with the positive output (black probe) in the terminal and negative wire (red probe) from the pin connector, is also OK: ![](/upload/album/52/59/f6/b3480e0a8120qmDLqpxy.jpg)
But if both probes are in the terminal side, it will not work (the picture is the first one) : ![](/upload/album/52/59/f6/b3480e0a8383VCgzwoyy.jpg)
So, there is no connection between the negative terminal (*) and the pin adapter of negative wire (**) Use this function with beeping sound: ![](/upload/album/17/9e/2c/6a81d2080207VhUvKQ5M.jpg)
Cut the top plastic terminal with a knife: ![](/upload/album/48/27/c4/c5d12e913141qjmgA0iL.jpg)
The copper wire (negative) is exposed (green circle, sorry, not focused): ![](/upload/album/48/27/c4/c5d12e913313IFQgacfG.jpg)
Then cut a piece of copper stripe (lower part) from a copper sheet (top part): ![](/upload/album/17/9e/2c/6a81d2089568M1waTiHT.jpg)
Take the brass tube out from the negative terminal: ![](/upload/album/17/9e/2c/6a81d2089680iY8Q1bC2.jpg)
![](/upload/album/17/9e/2c/6a81d2089711On5MDIRZ.jpg)
Put one side of the copper stripe into the negative terminal and also put the brass tube back into the negative terminal: ![](/upload/album/17/9e/2c/6a81d2089890mHsSMJpF.jpg)
Use a hammer to put the brass tube in: ![](/upload/album/17/9e/2c/6a81d2089959L8mbENCy.jpg)
Now the brass tube is in and then bend the other end of the stripe to the exposed negative wire (notice the exposed copper wire in green arrow): ![](/upload/album/5b/33/7e/3358e3a73847hgU1SGAy.jpg)
Wrap the terminal with electric tape: ![](/upload/album/17/9e/2c/6a81d2080510Dv35EXiC.jpg)
Finished terminals: ![](/upload/album/17/9e/2c/6a81d2081722QdlZoB5Y.jpg)
It is done: ![](/upload/album/17/9e/2c/6a81d2081676Kr1JR8mV.jpg)
Plug it in the vacuum cleaner: ![](/upload/album/17/9e/2c/6a81d2080632BZxSERFp.jpg)
It works: ![](/upload/album/17/9e/2c/6a81d2080671aZiiUX4z.jpg)
