I just bought at 1993 318iS. Coming home from work at night, I noticed the battery light coming on, but barely. As I get the engine up to over 3K it disappears for a while and returns. After about 10 minutes of driving, I noticed that all of my dash lights are brighter and the battery light is off.
Earlier in the week, I turned on my high beams and my ABS light started to flash. Also, my radio will turn off and on by itself.
The previous owner replaced the alternator, belts and battery in August 2012. Do I have a bad alternator or a grounding issue? Anybody been down this road?
