I have a 2014 Chrysler 300C with about 60xxxkm on it. In the past 3 or 4 months the battery will die over night or over a couple nights. The cluster screen shows white and the gauges act all strange and it will barely have enough juice to start or it wont start at all. The other day I decided to find the source and found a 2.5 amp drain on the battery when the car is off. I put a test light from the negative post to to the negative terminal and pulled all the fuses to find which on was staying on and I found that fuse 7 Exterior Lighting #2 , fuse 6 Exterior lighting#1 , fuse 23 Fuel door/ Diagnostic port, fuse 32 HVAC module/ cluster, and fuse 33 Ignition switch/ wireless module were all staying on. I understand that there will be some systems that stay on when the cars off but I'm not sure which ones and if they can possibly affect other circuits. I'm at the end of my electrical ability and am pretty stumped as to how to fix this.
