Replace the DC plug on an Apple iBook silver "yo-yo" power adapter.

Step 2 Selecting the Replacement Connector

The connector is clearly a 1/8" stereo headphone plug with a custom metal shell around it. I bought a replacement plug but it didn't look like it would be easy to fit it inside the metal shell.

I decided to hedge a bet and just install the replacement jack without the original metal outer shell.

Although the outer shell was connected to the middle-ring and to the wire shield, I guessed that the shell itself was not connected for supplying power. I would have to take apart the iBook to find out for sure, but for the time being I just assumed it wasn't connected. If the resulting repair failed to get the iBook powered, then I could assume I was mistaken.

Interesting.... I went to my local Radio Schmuck and got a 1/8" stereo phone plug (part #274-1547), and it's too fat to fit in the DC-in port on my iBook (dual USB). Does anyone have an idea what's the correct one?

Ok, for those of you with an IBook dual USB, it's probably a 3/32 stereo plug. (dang, I hate replying to my own questions!) Of course the local store didn't have one, so I'm making do with a 1/8 and an adapter. Still cheaper than a new yoyo.

Just make sure to check the polarities and voltages and let us know.

Exactly how do you check the polarities and voltages? I repaired the plug on my power cord and am afraid to plug it in. Thank you!
