We had this old NM-CD AA, AAA, and 9V -All-In-One Battery Charger. Its very old and is currently not anymore working. I wanted to know the rating of the Transformer inside it so i can reuse it for future projects, BUT, there aren't any part numbers or anything written on this transformer.. so how do you find out a rating of a transformer if you only have as far as a multimeter and internet?...
I'm sure this isn't a 220v-110v, but probably to lower voltages.
The two blue thicker wires went straight to 220V AC mains on the charger's design. The PCB beside it was previously connected to it. It only had Resistors, Diodes, and LED's then straight to the AAA, AA, and 9V battery connection.
