I just bought a new duralast gold batterie for my hellcat charger, the car has intermittent starting problems. I thought it was for sure the batterie but that did not resolve the issue, the car has a lazy crank and is very reluctant to start. Today i was sitting in it amd watched the volts drop down from 9.1 8.5 before i decided to shut it down. Things like the radio had turned off and the car was starting to display warnings .. service active dampening/ electronic stability control etc...
I also am getting a faint electric smell under the hood.
I am thinking of removing the alternator and having it rebuilt by a local shop down the street.
Any body have any input or suggestions?

Check all fuses first.

Alternator connections & all electrical ground points...

Any mods?

What model year & mileage?

I have checked all electrical connections and grounds numerous times.
Only mod is a legmaker

Its actually a custom build i did into a 2015 Chrysler 300 and now its a hellcat after a full conversion using ALL charger hellcat parts and wiring.
Never had this issue before and now i have this issue.

Check the continuity of the Field Wire from the alternator to the PCM. The PCM controls the Field Circuit based on system voltage needs & thus alternator voltage & amperage output.

Battery Voltage should also be available at the alternator Battery Terminal all the time.

Well, did you ever check the battery (fully charged) voltage while running/charging with a voltmeter?

Lol
You can have the battery and alternator tested in the car very easily by a parts store or mechanic.
Have you done this ?
Or just tossing parts at it?

I checked the voltage at the batterie while the car was running with a volt meter and the voltage was dropping while the car was running.

What about the Field Wire/Circuit?? There's either Voltage to it or it grounds at the PCM. You'll need a wiring diagram to know. Nothing happens with a dead Field Circuit.

Seems to be your charging system, swap out your alternator.

Alternator was fried, had it rebuilt and got a new american made batterie as well.
Finally got a code for P0340.
Swapped out the cam position sensor and the car starts right up.

Great, thanks for the update.
