Asked by Aug 29, 2014 at 11:19 AM about the 2002 Chrysler 300M STD

Question type: Maintenance & Repair

Car wouldn't start and would not take a jump.  Battery only 8 months old.  Took
battery down for exchange and they said battery was fine.  Bought new battery
anyway.  After putting new battery in car would not start but would take a jump.  Drove
and worked fine.  No dim lights. All electrical seemed fine, and would restart a few
times during the day.  Turned car off last night and woke up this morning to no
electrical power.  Dead.  What is wrong with my 300m?

Have you had the alternator checked?

No. At this point I cannot even get it to a place to have it checked. But last night while driving, using a/c, headlights, radio etc. there were no electrical problems. No dim lights etc. I am not an expert but it does not act like a bad alternator.

Hi Mark. My instincts tell me you are probably right. I will put a new alternator in. The one that is in there is at least 7 years old and possibly came with the car in 2002. (I bought the car used in 2007). Thank you for your help.

Easy way to check your alternator....get a voltmeter 0 to 15 volts and with the engine turned off check the battery voltages...say 12.6 volts then start the engine and measure the voltage at the battery again...if the alternator is doing its job the voltage should be 2 to 4 volts higher. If not, it a bad alternator... If you still suspect the alternator....remove the alternator fuse overnight...also new batteries can go bad..with it fully charged disconnect one of the cables and leave it sit overnight and if its unable to crank the engine in the morning ..you've found the culprit...bad batteries does hold a charge for very long...
