@ianfink the DS has a fuse that protects the power circuit. You want to check that one since they love to fail. You will definitely need a multimeter for that. Proceed with what my colleagues answers as well. you do not know the history of the console. Corrosion is one of the most common issues with the handheld consoles.

Okay, you will need at least a voltmeter or a multimeter (do they even still make dedicated volt meters?;-). Set is to something in the 10 Volt DC range. Then plug the AC adapter into your DS. You should measure P7 (which is your battery terminal. REd arrow is the positive and Blue arrow the negative pole. What voltage do you get? You may have to try to push the on button and see if that changes the voltage. You could also measure the voltage on the left and then the right side of the fuse. Both are positive pole. On your meter you will use the positive probe on one of the sides on the fuse. the negative probe from your meter on the negative (Blue arrow) on P7. Let us know what voltages you get. Also, if this doesn't make sense, let us know. We can always try and guide you further.
