Step 1: Open the Case
A major challenge in opening the case was these security type screws that have the thread poking in the middle of the nut and the slot is on the outside of it. Since I didn’t have an appropriate screwdriver, I managed to improvise and use two smaller screwdrivers to push on the two slots at the same time.
Step 2: Inspect the Circuit and Principle of Operation
To learn how the charger worked, and how it was built, I used my multimeter to trace out all of the connections, and also I did some voltage measurements in different parts of the circuit.
Step 3: Test the Output of the Transformer
To verify that the transformer was working properly, I completely removed it from the circuit and I measured the output voltage on the entire winding and on the half tap as well. The voltage measured about 8V on the half winding and close to 16 on the entire winding which meant that the transformer was good and something else is the issue.
Step 4: Bridge Rectifier Wiring
Now, the only thing left to check was the bridge rectifier so I measured each diode separately and it seemed to be working. However, its construction is a bit exposed so over the years the material that makes the diodes have developed a relatively large voltage drop, cutting the output at half on the charger.
Step 5: Install New Bridge Rectifier
The installation of the new bridge rectifier was really simple as it was a lot smaller than the old one. Since I don’t have wire crimps to add connectors I added solder directly to the pads on the rectifier and soldered the wires.
Step 6: Assemble the Charger
With all of the electrical connections made, I returned everything to the case and I wiggled with the wire mesh on the outside in order to get it flat and sit properly in the dedicated slot.
Step 7: Replace the Alligator Clips
As a final step, I removed the old rusty alligator clips and I’ve added new ones by first flooding the clip with solder and adding the wire to that solder joint. For some extra relief on the wires, I’ve bent the outer flaps over the wires and I made sure to add the cover to the clip and call it a project done.

Background and Identification
Car chargers are devices that connect to a car’s auxiliary power outlet on one end and a charging port on the other end. This auxiliary outlet used to be commonly used to power an electric cigarette lighter. As the harmfulness of cigarettes become more widely known and their use decreased, however, this port changed function.
