SOURCE: Battery and Alternator Good. Alternator not working. HELP!!!

djn, I believe you have some accessory that is on when the key is in the off position.
Check to make certain glove box light is not on when the glove box door is closed and the trunk light is not on.
If you have an aftermarket radio or any added accessories make sure they are not wired direct to battery voltage.
If all that checks out, disconnect the battery negative and connect a test light between the battery and battery cable. If the light is on you have a drain in the electrical system. Leave the light connected and begin removing 1 fuse at a time until the light goes out, that will tell you what component or circuit is draining the battery.
Last resort, you may have an alternator drawing the battery down.
Good luck and let me know.
Regards,

SOURCE: Daughter called me ..car wont

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

Put a crank position sensor on ,car finally started with a jump start took the cables off and died now all it does is click

NO CAR TOLD YEAR,MAKE OR MODEL NOR VIN#
BATTERY IS DEAD. WHY AND HOW WHO KNOWS?
WE CHARGE THEM USING A TOOL CALLED CHARGER

AND IF THAT FAILS TO MAKE OLD BATTERY CRANK ENGINE
THE BATTERY IS REPLACED. NOW.

EML IS CALLED CEL.SES AND MIL LAMP
IN ENGLISH IT IS CHECK ENGINE LAMP.
IT JUST STARTS SO THERE IS THE 1 KEY TEST DONE.
WHEN IT STARTS AGAIN
WE WHIP OUT THE OLD DMM,VOLT METER.
AND CHECK BATTERY LUGS FOR 13 TO 15VDC AT IDLE
BELOW 13VDC THE ALTERNATOR IS DEAD OR ITS FUSES BLOWN.

THERE ARE 6 CAUSES OF NO CRANKS.
FUSE] BLOWN
BATTERY DEAD (IT IS)
KEYSWITCH BAD (ST PIN)
PRNDL SWITCH BAD (AKA. PARK NEUTRAL SWITCH)
CRANK IN NEUTRAL NOW, DOES ENGINE START?
STARTER RELAY BAD

OR ANY WIRE ABOVE CONNECTED.

OR BAD BATTERY CABLES OR LUGS LOOSE OR RUSTY.
THE BATTERY WILL BE DEAD IF ALTERNATOR FAILS

MOST CARS IF ALT FAILS AND WE DRIVE 30 MINUTES AND ENGINE DIES, FOR DEAD BATTERY./ NIGHT TIME LESS.
AT IDLE THE DAYS CHARGE/BATTERY LAMP MUST NOT GLOW.

2004 Pontiac Montana -brand new battery, new alternator(not rebuilt). have to jump start and runs for a while then dies some times wont take charge. battery will die not running in a day. very intermi

First, you can't and shouldn't test an alternator by disconnecting the battery cable while the engine is running. You run the risk of cooking the alternator and the computer. Thats how we used to test generators back in the last century.
Is the check engine light on when the engine is running ? Is the battery charge warning light on ?
There should be a fuseable link between the alternator and the battery that could keep the alternator from charging the battery.
The ignition module would have no effect on the charging system.

Just clicks when ignition is turned

Check battery. If a jump starts the car and then it dies shortly after then your alternator is bad if it does not die or does not start from trying to jump start then it is your battery. Your battery may be dead if the alternator went bad because the alternator was not charging it like it should and the battery was running the vehicle. which sounds as if it may be the case. Hope I could help.

My car started dying and now hasnt enough charge to start

sound like bad battery cables.replace them.the positive battery cable is old and have a lot of resistance not allowing power to the alternator to charge battery.if battery cable good check alternator connector wires.make sure they are not damage also check alternator fuse and fuse link.turn off radio before removing battery wires so you wont lose radio code.

Pontiac Tempest shuts off once I turn on my headlights

Investigate the battery and the alternator.
The battery's only job is to start the car.
The alternator's job is to power the electrical supply for the car.

The battery can go bad at any time, and the alternator is probably is putting out only enough electricity to only keep the car running. And not enough to power charge the battery and power the headlights.
