Not an electronics guy so riddle me this if you can please
A friend brought the transformer for her Roland piano into a local electronics place for repair. The output on the transformer should be 12v DC \ 2A. When she brought it home it wouldn't power the piano so she asked me if I could test it. My Fluke meter tell's me it's outputting between 15.9 and 16.3 volts every time I test it. I've tested half a dozen other transformers and they all test within 5% of the expected value so I'm assuming my meter is good.
They replaced the cable entirely on the transformer. It's an older unit and has screw to take off the cover so is serviceable by a professional. Can anyone think of any reasons why the unit might now be outputting the wrong voltage so I can send her back to these guys armed with the right questions?
