"Check Charge System" Message displayed battery voltage decreasing
Okay, so I'm guessing this message means my alternator has decided to die, as the battery is only a year old. As I was driving home, the battery voltage kept getting lower and, now, after turning the car off, it won't start back up. I called and I can get a rebuilt one for a decent price, but have never replaced one before. It looks like it won't be too hard...are there any things of note I should make sure to attend to when pulling this out and putting a new one in? I would hate to break a finger nail :-P Actually, because of all the integrated computer ****, I just want to make sure that there aren't any other relays or misc gadgets that are going to be affected

What do you mean won't stay charged ? Battery dies while driving , dies over night ? Is the battery symbol lit on the dash , check charging system message on driver info center ? If it drains over night there is a parasitic draw on the electrical system ! If while driving the battery goes dead it's not charging , with a new alternator the problem is in the electrical circuitry . Blown fusible link or fuse . This charging system is controlled by the PCM - engine computer , the heavier gage wire on the back of the alternator should have battery voltage , if not blown fusible link near the battery . The connector with three wires ,one should have B+ voltage , the other two come from the PCM .
check quick connect plug on alternator .see if conection or wiring is good. also checkthe fuse, they tend to blow when you instll your new alternator if you create an arc.last check your belt and tensioner. with key out of ignition! see if you can spin alternator blades with belt on. if so tensioner is bad
If you know for a fact the battery and alternator are good, the problem would be in the wiring between the two. You should have battery voltage at the alternator with the engine off. Check for voltage at the alternator and the starter cables. There are fuseable links that look like regular wires but have fuse wire inside.
Hello...A red battery light or image usually means there is a problem with your charging system..either your alterator is either not operating or emitting low voltage usually because of diode failure...alternators generate Alternator Current(AC) which is the same of household current...but the vehicle can not use this...It doesn't even register...The alternator has diodes which convert AC current to DC(Direct Current) which the vehicle can use....If the alternator is not doing it's job...The vehicle will pull current from the battery while the vehicle is operating..which is not good.The alternator should be able to run the vehicle...all the accessories...and charge the battery all at the same time...Drive it into an auto parts store and have them test your charging system before you get stranded...and most of the time...the car will die at night because of the headlights.....Let me know what happens...I hope this was helpful.....PEACE.....
first check battery for Am and voltage . replace the battry if it's use for more than one year. fix new battery and folow up by drive your's car two kilometer then check battery cable if it;s hot means overcharging . you can check with use head light accilerate if lights more white or more high . voltage regulator must be replace for the alternator .
" service charging system ", means you have an issue with your battery, your alternator, or your voltage regulator. Something is causing your battery not to charge properly. You should have it checked as soon as possible. This could keep your vehicle from starting next time.
The first thing to do is have the battery tested and then the charging system checked, this will show you if its overcharging,if it is overcharging then take a look at the wiring going to alternator,and also a bad battery can also cause a problem so first find out if message center is displaying the correct message, this will show if center is okay then move on to battery testing then alternator test, there may be a problem with the wiring or a defective alternator.
