Hey there HardstyleZilink,
Just had the same issue. Ended up being that the pins on the dock connector were bent. Bent them back and iPod started to charge fine.
I also found out it was under warranty, so to avoid it possibly happening again I sent it back to apple and received an exchange.

Hope this helps buddy.
Best Regards,
