Battery light frustration on 78 280e
So I am helping my friend with her 1978 280E and the Battery light keeps coming on. We replaced the alternator first. Car ran fine for a couple weeks then the battery light came on and ran the battery down. Charged up her battery on a charger and it lasted about a week. I read 13.85 volts while the car was running on the old battery. Decided to throw a new battery in there today and it read 14.36 volts on the battery while running. Sent her down the road and now the battery light is back on. The belt seems tight to me. Any ideas?
