I had the same issue and was driving me nuts, after lot of electrical and parasitic testing with few new alternators and a battery, found the problem, was the IBS ( intelligence battery Sensor ) which is connected at the negative post on the negative cable, sensor was bad giving wrong input to the car PCM and not allowing to charge. Hope this helps.(y)(y):giggle:

2013 300c awd

Battery saver mode light on, radio dimming. Brought to Chrysler light wasn't on anymore. They said that it tested fine. They said to call corporate and deal with them. Twenty minutes later after giving the dealer a lechture about that I wasn't going to end up on the side of the road. I will be getting a new alternator and then because I don't have the energy to continue yelling buy a new battery. Bought a lifetime warranty for $4k and it is useless that the mechanics cannot figure out this problem. I will update if I have this problem again after I pickup with a new alternator. Don't just be passive and let the dealer give you they are just the middle man excuse. Fight for your car to be fixed right.

The alternator has three terminals: +ve, connected directly to the battery, -ve to ground and a field control wire connected to the ECU. It is the ECU field connection which provides fine control over the alternator output. It is not uncommon for this field wire connection to be overlooked when installing an alternator and with predictable results. The integral alternator regulator only provides a coarse function.
