I've got an old Sony Ericsson with a charger that's sustained some damage. The cord has been melted and flattened in one place. Neither the charger nor phone has been used in a long time. The battery for the phone is not charged and at right now the charger doesn't seem to charge the phone.
Using a multimeter, I tested the voltage on the pins of the charger. I get the correct 5V readout. This leads me to believe the charger still works. However, when I try to read the amperage from one pin to the other I always get zero. Can anyone tell me why this might be?
