Reocurring need to charge battery to srart, though dash lights up
2000 Chrysler Concorde with otherwise good history. Battery replaced in 2005 and 2007. In 2008 on 3 occasions battery had to be charged to start. Recently driven 25 miles to resturant in dry weather and started up fine 1 hr later. Drove 15 miles and it seemed to falter momentarily and felt like it shifted down, though dash showed in drive. I then manually shifted it down and run another 10 miles nicely before quick falter then about a minute later it shut down, It had normal headlights. When I turned key on, the dash lit up as it always did when turning key. It did not try to turn over. Just clicked once each time. I tried key 3 times.
Using battery charger from our own repair garage works fine, and it's then good to go. I did not try jumper cables but was towed once and the other 2 times it was parked in garage where it is always kept .
Re: Reocurring need to charge battery to srart, though...
There is a fuse box under the hood with a power wire running from the battery to this box. Check for corrosion around this box and make sure the connection is good. Had a similar problem everthing checked out good, then found this wire had a terriable connection, check this out and clean the post for the connection.

Did you have the alternator checked? When the battery light comes on, it indicates either the battery is very bad and is draining power from the system, or the alternator is not providing enough voltage to keep the battery charged.
Once you have the electrical problem taken care of, and the system is getting proper voltage, you can see if you continue to have problems with the engine performance. (The crankshaft position sensor has nothing to do with battery charging)
The easiest way to figure this out is to read the touble code that triggered the check engine light.You will probably want to clear the code after making the correction,otherwise,it colud take a lot of ignition cycles to go out on its own.A basic code scanner is about 50 bucks,which will pay for itself in one use! The battery fire probably melted a nearby wire,connector,or sensor.
Actually, although rare, this could be a computer issue. The voltage regulator is built into the computer on your Concorde and may not be completing the circuit.
I'm not sure how you verified the alternator is good other than you removed it and had it tested.
To verify the problem is in the computer, find the orange/dark green wire that supplies power to the alternator. This is fused power to the field. Verify it has 12.5 volts positive. If not, that will need to be repaired.
If it is OK, then find the dark green wire that also hooks to the alternator. This wire leads to the computer which controls the amount of ground to regulate the amount of output from the alternator stator. Attach a wire with an alligator clip to the dark green wire terminal on the alternator. Attach a voltmeter to the battery. Start the car and touch the other end of the attached wire for a few seconds (no more than a minute) to the NEGATIVE battery terminal. If the alternator begins to charge you will need to verify the green wire is good to the computer. If OK, replace the computer.
If you need more assistance with this issue, let me know here. Thank you for using FixYa. KL
Make sure the connections and the cables are good.No corrosion on cables.If the lights in the dash flicker this is usually a sign that the battery is not good or it is not making good contact.Have the charging system and battery load tested.Hope this helps.Good luck.
the most common cause of this by far is lights left on by defective switchs, these include the map lights in the visors, the glove box light due to a defective switch, the trunk light and the hood light if equipped, check it at night and look for a faint glow, the other much less common cause is the alternator has a defective diode and allows a small current to pass to ground drawing the battery down..
1999 CONCORDE: check the battery terminals probably they are not tight enough...something like that happened to me just the lights turned on and the car seemed to be dead, the battery is still ok since then. I just needed to buy new terminals.
Clicking??? Probably starter/alternator. does the starter turn? The clicking, is that all you get when you turn the key? Have the battery checked and make sure its holding a charge. If battery holds a charge, its time to have your alternator tested, if the alternator checks, then the clicking may be the starter/soleniod. Places like autozone will check the battery/alt for free, provided you can still drive to get there.
