iPhone 3G doesn't charge (dead fuse)

Hello,

I have a iPhone 3G that does not charge. I checked the charging fuse and it seems like it's gone, so I put a small bended paper clip to short-circuit it and plugged the usb to my pc.

Nothing happened after 5 minutes...

how can I check the dock connector and if the current is arriving to the logic board?

Did you check for power on your battery connectors? Paperclip? Darn, that space is so small, how did you manage that:-)? Are you sure you did not short anything else out. A small dab of solder or a circuit writer pen would have been plenty :-)

I did not short anything, however now I have put a small copper wire around it; didn't think about the circuit writer pen... I don't have one... Would a normal pencil do the job?

Can you tell me also how to check the dock connector?

I also tried to measure the voltage on the dock connector where you can see the > sign (and the other pin of the tester touching the chassis)

I don't know if it is the right point to test

It shows 0v with the cable unplugged and 3.7v with the cable plugged

Sorry, a regular pencil does not work. Anyhow, check on here http://pinouts.ru/PortableDevices/ipod_p... for the pinout. It should help you when you measure at your dock connector. Do you have any experience with reading schematics?

I don't think that one is useful, since I don't know which inside contact correspond to the pin outside

Today I got a working 3G; I tried to put the logic board into this one and it still does not work; it doesn't turn on, so I think it's something about the logic board
