What is your question?
Replaced battery alternator checked anything I can think of & my car won’t charge radio turns on then off repeatedly when it does start & drains a fully charged battery in seconds. I’ve checked fuses and relays also noticed beforehand my headlights went out and park lights after that…replaced the plugs now they do work but car won’t stay running very long at all. Could it be my tipm? Or computer considering my voltage regulator is located in my pcm? Plz help located in atkins Va!
What makes this problem better or worse?
Maybe a bad ground?? Fuse box?? PCM?? Radio issue?

Hello, I’m Pete from the Car Genius team at RepairPal. I’m sorry you’re dealing with this concern on your Chrysler 300. Based on the information provided it sounds like your battery is not receiving a charge from the alternator with the engine running. It also sounds like you have already replaced your battery and alternator as well to try and resolve this concern without success. A loss of charge will cause the voltage to dip below 12 volts with the engine running and when this occurs this causes various electronics to either stop working all together or work incorrectly. What can cause a concern like this with the parts that were already replaced are a blown fuse, damaged, corroded, or loose electrical wiring or connections, a faulty PCM, or even an internal PCM or TIPM (since the TIPM is one of the main electronics computer in this model). I recommend having all of these checked into to help pinpoint which component is creating this concern so it can then be repaired properly to resolve this issue. The testing involves may require special test equipment to be able to pinpoint the concern properly, test equipment that most shops and dealers use. I wish I had some better news to give you on this.
