If you mean alternator is not charging battery
a device called a voltmeter is needed to diagnose this problem
Jump start vehicle , disconnect jumpers from other car , use a voltmeter on the battery terminals to measure (red lead on + or plus and black lead on - or gnd ) have a friend rev engine slighty if voltmeter rises it's reading to 13.8 and stays there no higher you just have a bad battery you'll need to replace it but if reading moves all about your regulator is bad that will need to be replaced (usually ruins battery as well) and lastly if reading stays low and does not move up but goes down your alternator is bad that will need to be replaced

Note : when dealing with batttery on car allways shield your eyes just in case there is a fault and battery explodes , acid in your eyes is no good

Sounds like a bad altenator. Usally accompanied by starting problems. To check the altenator, disconnect the battery while the vehichle is running, if the engine dies when you disconnect the battery, then you'll be looking at a bad altenator. If altenator checks good, then post back with a more detailed description of symptoms.

Tip

Starting and Charging
All starting systems are basically the same in operation for manufacturers. The starter takes power from the battery to crank the engine. Generally the large wire on the starter is from the battery and the small wire is from the ignition switch. The large wire will have battery voltage on it all the time, the small wire will only have voltage when the ignition key is turned into the start position.

The altenator on all vehicles is designed to provide power for all car electronics while the engine is running, there is a large wire (usually red) that comes from the battery, and two to three small ones that come from other circuts to regulate how much power comes out on the large red wire.

The only relationship between the altenator and starter, is the battery, it is important to remember that the starter takes power in the form of amperage from the battery, while the altenator send power in the form of amperage to the battery. Thus an altenator can never be the cause of a vehicle that will not start. These two systems only share the battery and other than that they are not connected.

What could cause an altenator not to get power
Alternators give charge not get a charge. Check that you have connected up the wires to the alternator correctly. Check drive belt for tension and condition. If it still will not charge have a qualified auto electrician check it over.

Replace the altenator. It has gone bad and every thing is running on the battery.

Charging system alt does not chareg in truck. Bench tested O.K.
Measure the voltage at the big wire on the altenator engine off, do you have power? Check in your distribution box under hood, find the two rows of fuses located inside the box on the outer edge, look at the outside row from front to rear the 4th fuse (# 11/ 20 AMP fuse), is for the altenator field, make sure this fuse is not blown, if it is good and you have battery power on the big wire at the altenator, then replace the altenator. Hope this helps, let me know.

Cars lights are going bright and dim . changed out battery today and alt tested fine.car ran fine again until tonight then back to losing power
mcdevito75 here, Sounds like the regulator inside the alternator, re test altenator with the headlights off, then on, any lower reading from the altenator with the headlights on, could mean a bad regulator, in the altenator, all 1 unit altenator gets changed.

Altenator is not charging the battery
sir , the altenator has 3 wires at the connector correct ? a white/red , a green/white and a black , the white/red wire is involved with a 10 amp fuse to do with the charging meter / gauge , the fuse located behind left side of dash .. the green/white wire is is involved with 2 fuses , a 10 amp ECU fuse and a 25 amp Main fuse located at left rear of engine compartment main box , and the black wire is involved with a main 80 amp fuse at the main box also . both of these 2 wires end up at the positive side of the battery , please verify all these fuses are good . if they are indeed good , then open wiring would be next step verify continuity on black and the white/green wires . i would post a link to diagram but autozone repair info site is down at this time . if ya need more help , please ask .

Checking the power steering fluid levels
the power steering resevoir is underneathe the altenatror or your vehicle. you have a gm 3800 series II engine the resevoir is located near the fire wall on the passengerside right under the altenator. the easiest way to check this is to remove the altenator. I say this because there is not much room to put your hands in that area because your coolant overflow tank is there as well. disconnect the ground to the battery first. then disconnect the power lead to altenator. remove serpentine belt. then remove the plug from the altenator. remove the bolts to the altenator and move the altenator aside there you will see the resevoir for the power steering. installation is in reverse order... please rate this......thanks
