Sounds like it needs an alternator. If the alt. is working correctly it should charge at 13 - 15 volts. Your car is a 12 volt system. anything less than that is not charging, it's draining the new battery.

You need 13.8 to 14.5 volts for proper charge. I suggest that you pull the alternator and get it bench tested. There is a diode trio that controls the regulator, and when a diode fails, issues like what you describe, happen.

Charging system failed. Why is new alternator output ranging between 11 1/2 and 12 1/2 volts?


11 1/2 to 12 1/2 is not charging . That's less then battery state of charge , Battery stat of charge should be 12.6 volts , when charging with a volt meter you should see 13.1 to 14.1 volt at the battery posts . Is there a battery symbol lit on your instrument cluster ? Is there battery B+ voltage at the wires hooked to the alternator How to Test an Alternator

I have a 2002 GMC Envoy, Quite frequently my charging light will come on and state that I only have 10 volts coming out and then all the sudden jump to 14 and work perfectly fine


How many mile are on you vehicle ? Have you ever had Alternator replaced before ? You alternator maybe starting to fail , brushes or the voltage regulator .
Charging System Indicators
BATTERY The IPC illuminates the battery indicator when the following occurs:
?€¢
The PCM detects that the generator output is less than 11 volts or greater than 16 volts. The IPC receives a class 2 message from the PCM requesting illumination.


?€¢
The IPC determines that the system voltage is less than 11 volts or greater than 16 volts. The IPC receives a class 2 message from the body control module (BCM) indicating the system voltage.


?€¢
The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.


?€¢
The ignition is on, with the engine off.
BATTERY NOT CHARGING The IPC illuminates the battery not charging indicator in the driver information center when the following occurs:
?€¢
The PCM detects that the generator output is less than 11 volts or greater than 16 volts. The IPC receives a class 2 message from the PCM requesting illumination.


?€¢
The IPC determines that the system voltage is less than 11 volts or greater than 16 volts. The IPC receives a class 2 message from the body control module (BCM) indicating the system voltage


It would be a good idea to have it checked out , most auto parts stores will do this for free !

Why did my lights go down and battery volts drop?


First put your battery on a slow charge 6-8 hrs.then check the batteries voltage it should have at least 12-12.8 volts if it does'nt then you need a new battery.If has 12 volts after its charged and goes dead after its installed in the car then you need a new alternato.

I think I have an alternator problem? The charge needle on the dash guage is spiking to 16 volts off and on. I put a voltmeter to the battery and it is only charged to about 11 volts. With the engine...


Hello
The normal charge of alternator on idling is about 13 to 14 volts. 12 is acceptable but keep in mind it will need attention soon. The needle fluctuates due to the revs of the alternator - there is nothing to worry about. Just look that the charge is always above 12V on idle.

Have a 2004 saab aero 9-3. Recently battery died. It was shorted. But 6 years old. Replaced battery. Now often when trying to start, makes one loud click and won't start. Displays flicker and/or go black,...


I was having the same problem with my 2004 9-3. I assumed the starter was bad and replaced it. I then charged the battery and found it wouldn't fully charge. After charging for several hours when I removed the charger I only showed 11 volts at battery posts. The new battery tested 12.8 volts and the car started well. With the car idling I tested and showed 14.6 volts at the battery post which confirmed my alternator was charging.

I do believe I replaced the starter in error and that it was just a bad battery. When my battery was failing I had dim headlights and flashing displays that you described and the clicking noises also. When I put jumper cables on my saab and let the bad battery charge for several minutes the car would start right up and the headlights would brighten up and even though the battery was bad the idle voltage at the battery posts was increased to 14.6 volts coming from the alternator.

Remember to remove the jumper cables quickly once the car starts to avoid possible electrical problems.

I have had bad starters in other vehicles that would draw a huge load on the battery and jump starting them would sometimes give enough voltage to turn the engine over and start it.

Bench tests aren't always correct because the components aren't under a true load. I had a brand new alternator fresh out of the box last year that was bad and wouldn't put out good voltage even though it bench tested perfect. Go figure.

Check your battery voltage with the engine off. It should read over 12 volts if its charged.

87 toyota camry new battery wont keep charge, alternator checks okay, in dash bulb for charge and brake and lights stays illuminated?


Generally if charge light is on, alternator has a bad diode in it. This lets the charged battery lose its power by flowing in the reverse direction. It sounds as the alt., is either not connected right or is swtill bad
