have the alternator checked. Answer
You can check the alternator yourself with a multi-meter/ voltmeter. Start your car and rev to about 1500 rpm, touch the meter positive lead to the b-lead on the alternator, and the meter negative lead to the alternator case, or any good ground. You should read 13 to 14 volts, anything less than about 12.5v, and you've probably got a bad set of diodes and need a new alternator.
alternator needs to be replaced. battery also might be a problem due to the alternator not charging it
Alternator is not charging. Have it tested and/or replaced.
Your belt is correctly tensioned?
94 Buick Lesabre replaced battery and alternator and the alternator is not charging the battery. Battery light is on and off. Is this fusable link. If so where is it located
I have replaced the alternator then a blinking light came on and says check charging system. The battery was then switched out, the light continues to blink I had the new alt checked and it is working fine. Any suggestions?
alternator. go to a parts store and have them test the charging system. must will do that for free
check the alternator. Use a digital multimeter and with engine running you should have 13-14 volts at the battery. If less than 12.5 Alternator is not charging Also check the amperage the alternator is putting out.
It means something is wrong with your charging system. Can be a loose of corroded battery cable, defective alternator or a battery with a dead short.
Could be a bad signal sent by the computer or the alternator is not charging to full capacity. Have someone check the charging amps on the alternator.
The battery light can come on due to a low charging voltage. Check the alternator for full output, and make sure that the alternator belt is not slipping.
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alt belt.
could be the alternator or starter sounds like the alternator if the battery is gone flat get the alternator tested at auto parts or garage jump charging the battery might get you out of trouble for a bit
This is not a battery problem. Your charging system, the alternator, is not putting out enough juice to charge the battery until you reach 4000 rpm. Have the alternator and charging system checked.
The alternator is over or under charging.The alternator is over or under charging.
One possible cause is a defective alternator, Have the charging system checked.
Charge and load test battery- it may be not able to take a charge and need to be replaced You may a have blown fuseable link preventing alternator from charging battery
you may have a bad battery or a bad voltage regulator
If the light remains on then the system still isn't charging as it should. Check the plug on the alternator and also that the wires to the alt have a good connection.
charging system not charging battery with new batttery, alternator and fuel pump. what will make that happen ?
Is it charging, if not have you checked wiring to alternator.
have the alternator and the battery checked
Apparently the alternator is bad or the battery is shot, take the car to autozone and get a free charging system check.
Have the charging system checked. Possibly loose or corroded wiring, a loose alternator belt, or a bad alternator.
The alternator is over charging. you need to have the charging sytem checked.
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.
