Question about 2004 Dodge Ram

1 Answer

Charging system My charge light has been coming on followed by a decrease in speed and eventually dying out. Had the alternator removed and checked and it is fine. Was told that i may need to change the voltage regulator. Dealer says it is now part of the $712.00 PCM.  Is that the only way to fix this thing?

You can also try to instal a external regulator, from the 70,s or 80's but that will be like a good mikey mouse job,
if you can't affort to pay that money now, the only way is visiting auto electrical shops and ask for an external regulator, if they don't want to do it i will tell you how to do it, but if you want it original then have the computer replaced, but before replacing teh computer make sure you are getting igniton power to alternator at one of the small thing wires,
i will aprecviate your ranking and good luck

Is it the alternator?


Sounds like a charging system problem. The engine runs off of the alternator but if it is not charging the battery properly the battery will be drained until I engine will no longer run. You need to get the vehicle to a repair shop to have the battery and charging system check for defects

Have someone check the charging system on the truck. The light comes on when the alternator is not charging the battery.
Could be a wiring problem between the alternator and the battery.

it sounds like you have blown fuse to the Alternator.. I don't know what car you are talking about but they charging systems vary.. But if alternator isn't getting all the power it needs it won't charge. this should be checked.

good luck

Battery warning light is on, on dashboard panel.


hi the problem is the charging circuit is not working ,sometimes its worth a look under the bonnet to check if the alternator belt is still on and in one peice if it is slipping badly it wont turn the alternater at the correct speed to charge the battery .
if you can check the voltage of the battery when the engine is off should be about 12.5-13.5 volts
start the engine and check again should be about the same if it is dropping then I would suspect
the alternator is faulty
If the only symptom is the light coming on and there are no other signs of a problem like engine dying or lights going dim then you could have one phase of your alternator down that is putting the light on this can go on for a long time like this without any other problem but will eventually fail so
needs to be checked out

Why would the battery light come on but be really dim? it comes on when the rpm's go up


You may have an alternator that is getting ready to go out. Have you noticed a whinning sound that increases / decreases with engine speed? A diode going out in your alternator will sometimes produce a whine and will reduce the voltage produced, eventually not keeping your battery charged.

Take car to an auto parts store for alternator check. Many stores will perform this test for free.

Good luck!

I need to know why my check gage light came on and now my battery gage is low and my truck won't stay idoled and it dies and will act like the battery is dead which will eventually kill my battery but then...


You need t have your charging system checked. Low voltage can affect the engines sensors that monitor engine performance. If the battery isn't being charged while you are driving, it will eventually be drained and the engine will die and yu will lose power steering and brakes. If this happens in traffic or at high speed, you could be in big trouble. Have your alternator checked or replaced. Wouldn't hurt to have the battery checked at the same time.

My alternator went out so i replaced and its working fine but my battery still keeps dying its not takin the charge from the alternator and when i charge the battery it will start and drive some distance...


Sounds to me like your alternator is still defective. You don't need a good battery to run a car. Start car and remove (carefully...do not allow it to touch any metal), negative battery cable. If car dies it is the alternator. If it runs then the battery is bad. Hope this helps.

If I have helped you resolve your problem, please
consider giving me a good rating. Thank you.

Battery light indicator went on initially, and power to vehicle eventually died out; with engine sputtering.


If your battery light indicator went on it indicates that the battery is not charging because of either a dying battery or alternator or both!
With the red battery indicator on, the battery will eventually drain out (especially if the alternator is faulty) to the point where it will not provide the required power to the car electrical system ... thus causing it to 'sputter' and eventually die out - a sure sign it that you cannot restart the motor due to a weak of flat battery!
Hope it helps you understand the possible problem!
