1998 infiniti V6 when i start the engine up the battry light go out but the alternator is not not charging what all i need to check to fix the problem?
Loose beltunless there’s oil on the alternator or the terminal between the alternator and the battery is not tight
Inside the Alternator there is a little box with brushes in it, (little square pieces of carbon with wires attached). Check them for wear, if too short they need replacing....very inexpensive to do.

Hi, I can't tell you exactly what is wrong because there is too much involved at this point, what with 2 shops working with it, but I can give you some advise on what else to check. On the alternators and the wiring that supports them a small volt charge is taken off one of the slip rings, where the brushes ride, for the purpose of turning out the light. As I remember, this is a yellow wire that runs back to the dash.
To the alternator, it would be one of the wires that plug into the side of the alternator case.

well if the alternator is not putting out at least 13 volts when it running most likly its bad i would take it some place and have it checked again
You need to replace the battery to start with. you cannot test the charging system with the battery the way it is or you will get a false reading. Once you replace the battery, you can then test your charging system to see if the alternator is causing the problem. If its charging more than 14.8 -15 volts, its too much and you will need to replace the alternator.

Couple of things to check, first this may be nothing more than a belt that has loosened or stretched after the install.There should only be about a quarter of an inch stretch in the belt between pulleys. Caution - only check with engine stopped!!! The alternator causes a strong resistance when it is producing electric power, so slippage is to be checked first. Second, if the battery light comes on and off; it maybe acting in error. Get a multi-meter and check the battery voltage with car and ignition shut off. With the meter set on 12volt bat, place the black probe on the negative side of battery or ground and the red probe on the positive side of battery. If you get a reading of 12.66 v the battery is being charged and is full. If you get 12.45 you have a 50% charged battery. If less the alternator wiring needs further checking into as there maybe issues with wiring or the alternator itself. Hope this helps.

It could mean the alternator has gone bad already... with the car off, the battery leads should read 11-12V.. with the car on, the battery should read 13-14V.. if it's lower then it's not charging your battery and if it's higher, it's damaging your battery....
