94 golf, very weak power

I went to start, the console was making a clicking sound, I thought dead battery. I took out the battery to charge, charger said it was full without having to charge at all.

The grounds were all clean and intact, as are the posts. It's getting enough power for the dome light to faintly work and the console displays to appear.

Starting, auto door lock, headlights or running lights, all not enough power to do. When I try to do any of these things, it seems like it drains all the power there is and shuts the console clock and dome light off until I cease.

I'm very stumped as to the weak connection. It all happened overnight.

Take your car to auto electrician! Could be your alternator / electrical fault / power drain - take fuses out one by one and test for current drain. Check out articles on our website - there might be 1 or 2 about this. If not let me know!
