820-2936 fake charging

so this board will charge white the computer is off. Light comes on and os says the charger is plugged in. however the battery drains. He came in with a fake charger, so pretty sure that killed it. Where to start on this guy?
 
17/18/ - 3 ohms
27/28 - 2.02

These values are correct no? I tried a good magsafe, but not battery. Have to order one, do you think this could be caused by a battery?

20.2 ohms or 2.02 kohms? If 20.2 ohms, try another battery first. Bad battery will obviously not charge. Voltage on PPBUS without the battery?
 
2.02khoms sorry, my bad.

Computer will not turn on without battery. keeps resetting after 2-3 seconds.

ppbus is 12.57v then drops to 10.8v
