Battery not charging, firm green light on AC adapter

My MBP is about 4 years old, and the old battery had a cycle count of 1000+ so I bought a replacement last week and replaced it myself. Everything worked great (patted myself on the shoulder) until a few days ago I noticed it wasn't charging. The green LED indicator is on so I think the Magsafe isn't broken.

I've tried resetting the SMC & PRAM (or I think I did) but no luck. Not sure what my other options are but I think I'm going to try wipe the connectors with alcohol & cotton swab next.

Here is the info on my batts / AC:

Would it be safe to assume it's the DC in board or logic board that's causing this?
