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: Use two pin adapters (below, left, red and black) for the multimeter probes (below, right): Measured DC output from the wires of the charger (power supply ) side, is OK: Measured the DC output on wires from the terminal side on the vacuum cleaner, is also OK: Measured DC voltate with the positive output (black probe) in the terminal and negative wire (red probe) from the pin connector, is also OK: But if both probes are in the terminal side, it will not work (the picture is the first one) : So, there is no connection between the negative terminal (*) and the pin adapter of negative wire (**)Use this function with beeping sound: Cut the top plastic terminal with a knife: The copper wire (negative) is exposed (green circle, sorry, not focused): Then cut a piece of copper stripe (lower part) from a copper sheet (top part): Take the brass tube out from the negative terminal: Put one side of the copper stripe into the negative terminal and also put the brass tube back into the negative terminal: Use a hammer to put the brass tube in: 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): Wrap the terminal with electric tape: Finished terminals: It is done: Plug it in the vacuum cleaner: It works: |
