Hi, I don't post that much because my Dodge is always fine. But 2 days ago my Dodge Charger Police '07 stalled for no reason. All the lights came up on the dash.
I drove with 15 miles to my garage. There I connected a OBD meter (Autel Maxidiag Elite MD802) All kinds of faults came up and the battery was dead, less than 9.0 volts. I put the battery on a proper charger and came back yesterday. The battery was full (12,5 volts) I connected the battery again and put on the ignition. All lights on the dash were still there.
I started the engine and run directly. But after a few seconds the engine run like sometimes a misfire.
I connected the OBD meter again and tried to delete all codes but no results. Codes are still there. And another problem, my interior lights keep on burning. I can't switch them off.
What could be a possible problem ?

Thanks for the reply,
Johan

Bad battery is my guess,volts are not always an indication of a healthy battery.
Agreed. If this is the original battery, and especially if the car was actually used as a police vehicle, the battery is due to be replaced. These cars are exceptionally finicky when it comes to electrical power.

Have you had the alternator tested as well?
If the alternator isn't charging the battery, it will die again on you.

I just replaced my battery in Oct. It was the OEM battery and no problems to date. I figured it was time being that it's an 09 charger.
I went with a Diehard Gold North putting out 900 CCA.
With the really cold winter we had.... I'm glad I did.
No trouble starting it.

I replaced my 07 battery with one from Autozone. They sell one made for the police car which is the one I bought. A few more cranking amps wont hurt.

Agree, sounds like battery replacement time, and as mentioned....... have them check the alternator as well........but wondering why his interior lights would stay on and he can't shut them off? That makes no sense.

Thanks for all the tips. I have checked the battery and it's fine. My alternator is new. I checked the voltage on the battery with the engine running and it measures 14,5 volts.
I also came across this connector. I point my finger of the wire that is being used for this connector. any idea were it's from ? Maybe this connector gives all or some of the problems ? This connector was hanging between the engine and the chassis. As you can see it's a blue connector. It's on the drivers side.

How did you check the battery? Did you put it on a battery diagnostics checker? I vote for battery as well.

I did the test for the battery with a battery checker. It came out as good.
Also found the place for the connector. It was for the air pump.
I called a Dodger garage today and they said that all my computers are damaged.
Thursday I hope to know more.

What is a battery checker? Just a voltage meter? A proper tester you would probably not have at home the shop would have to do it for you. I would not trust anyone that says all of your computers are damaged. I still vote battery.

I've had 4 batteries on 2 vehicles checked by the dealer using a load test that they said were fine...only to find that they weren't really and needed to be replaced within a couple of months.

The simple battery test for these cars is to measure the voltage during starting a cold engine. If it drops below 11.0 volts while it is starting, it needs to be replaced.

What happens is that if the voltage dips too far when the car is firing up and the computers are coming on line, bad stuff happens. Think of it like you are dimming the power on your computer while it is booting up. :yikes:

With all due respect, I'm not sure why you aren't listening to all your peers on this forum. I believe each of them has said to change your battery and/or test your alternator. If your alternator is new, it's 99% not the problem, therefore it leaves the battery.

As stated by others before, CHANGE YOUR BATTERY! Especially if it's the original. My 2006 just had to be replaced last year and was doing all the funky crap you're explaining. It charged and tested fine, but when it came to running the car, it FAILED.

These dealerships or fix-it shops are trying to make money off you because you're on the hunt for a fix, when you could simply go with our advice and usually come out ahead of the game by several hundreds of dollars.

Change the battery, and go from there. If it doesn't fix everything, we'll come up try something else but don't throw money at a problem unnecessarily.

I have a new battery. Still no results. My alternator is new and it's charging. Next week a mechanic will pick up the Dodge and they will go read out the computer. So I hope to give some news next week.
Thanks for all the reply.

We found the problem !!! It was a bad wire behind fuse 17 (FCM) replaced the wire for a new piece and upload the software again into the PCM. Problem solved.

Thanks all for the input :)
