    I have a problem with my Nintendo Entertainment System aka NES AC adapter. I purchased the NES from a person and everything was working fine. He got the system to turn on and the system was functioning. When I went home and tried out the ac adapter, it wouldn't work unless I move the AC adapter unit to a certain angle. I flip it upside down, sideways and sometimes it will work and other times it will not. So I bought a digital multimeter. I plugged the multimeter red wire into the female connector coming out of the ac adapter (the plug) and the black wire to the ground or the outer side of the plug. I got about 9.9v iirc.

    The NES ac adapter specs are below.

    Plug type and size

    Did some googling and some say the wire inside could have been damaged? I have tried moving the wire that is close to the power brick and at one point i got voltage, then I moved it again to a different area and no voltage.

    I feel a bump on the wire's protective covering. Perhaps that is where the wire has split?

    Should I fix it by buying a new wire or just buy another original nes ac adaptor? Thank you.

    Buy another AC adapter. They are too easy to buy at a low price instead of possibly creating a fire hazard by doing this wrong.
