Yep bad alternator I have two 300c and both have had alternator replaced and week later you'll need a battery.

Either that or you fried the ECM when you removed the battery cable with it running. Never remove a battery cable with the engine running on a vehicle that has an Alternator, it causes a voltage spike that fries electronics.
