soooo yesterday i plugged in a mini fridge into the car adapter in the center console... and this morning when i tried to start my car all the lights turned off and it wouldnt start.... i unplugged the fridge after i relized i was an idiot for leaving it plugged in over night and the car started right up... Well now the check engine light wont turn off... and i drove 33 miles to work this morning... i figured it would turn off by now... anyone know what i should do???? my car is running fine now

Maybe the alternator hasn't juiced it all of the way up. I'd give it a little more time, personally.

But he was able to start once he unplugged the fridge, and he drove 33 miles in to work so that should've been enough time for the alternator to recharge. No telling on that one, that's new to me, in a Charger, that is. My Dad's got a portable fridge in his Durango but it was built with that in mind (came with it).

I can't even speculate, keep us posted man.

Just because he could start up doesn't mean he has 14.4 volts or whatever it is while running. It took me about 45 minutes to charger a battery from dead with a resistor coming off of another 12v power source.

Go to Autozone, or someone that will pull the code for free, and have them pull a code from it. You will have a starting point.

Also, if the problem is not there for so many starts/stop cycles the CEL will turn off (it took mine 3 starts/stops).

Turn the ignition key to ACC-ON-ACC-ON-ACC-ON (3 times acc-on) and then the dash display will show you the codes ...

Then let us know what they are, or search in Google for "DTC _ _ _ _" <<<< insert code there ;)

Well, that code would come up when the battery is low or the alt isn't charging properly ... you may wanna reset it with the Predator if you have one, or if not, disconnect the battery for a couple minutes ... but when you re-connect it, don't forget the reconnect procedure :
