Question about 1999 Chrysler 300M
How have you determined that the alternator (generator) is working fine?
Whilst the engine is running you need to see if there is at least 12 volts (usually 13.5V) across the battery using a voltmeter or similar tool. Also, whilst the engine is running, what happens when you turn the headlights on? (Does the car stall or try to stall?) This would affect night driving using headlights.
Most importantly, you run the risk of damaging the diodes on the alternator whilst running the
engine with a flat or undercharged battery.
There is also a regulator that controls the voltage from the alternator.
have you checked all fuses, including engine fuses located under the bonnet?
