Hello everyone, I’m new to this and I’m not sure how forums work, I need help. I was given a razor that is broken, and the first thing I did was check the voltage at the motor input, and it was 0. I disconnected the motor and measured the voltages on the batteries, and they were dead (I think they are completely damaged). So, I disconnected the batteries and measured the voltages, and it showed 3V at the output (the supply is 5V). However, when I connect the motor, the voltage drops to 0, and at the motor terminals, there is 5V with respect to ground. I’m not sure what to do, I know some basics about electronics and I know the motor is an inductor that short circuits, and I suppose that’s why the voltage drops to 0 due to the short, but I’m not sure if it’s a lack of current or what might be damaged on the board.
