The first thing I would do is remove the alternater and take it to an auto parts store and have them check it. If the alternater is working good, then check the belts are routed and have the right tension. Either of these can keep the battery from charging. It's very common that a rebuilt alternater isn't working properly. If all these things are correct, check the live wire to the alternater is live. If it isn't alive you have problems in the wiring and I would take it to a mechanic.

Just cause its a new alternator does mean it should work. I would check the charge when running cause it could just be a bad alternator.

SOURCE: alternator not charging battery

You may need to have it tested to see if it's working the connections on the battery may not let the charge through or the battery itself may not take a charge if it's no good

SOURCE: My battery dies i replaced a brand new alternator but still dosen't charge tomthe battery

The battery most likely has dead cells and not charging due to the alternator .The alternator is doing what it should, your battery just can't hold the charge the alternator is putting out. Go have the battery tested at a local auto zone or advance auto store. Free to check

Battery light stays on and drains battery. Brand new battery, alternator and starter?


What is year--make--model?
If something wrong with wiring circuit, somewhere, replacing the part won't fix it.
Make sure charging system is working properly. To look up wiring diagram, I need vehicle info. The battery lite is on even with key out? Unplug alternator, see if light stays on, check the alternator wiring connector.

My brand new alternator wont stay charged


Check the charging relay if working. You can find it in the fuse box which is either in the engine compartment or under the dashboard on the drivers side legroom.

Battery won't stay charged, it is brand new battery, alternator has been checked and it is good, blown BTN 60 watt fuse, on 1994 Mazda Protege.


The 60amp fuse probably is in the circuit between the alternator and the battery. Which would be why the battery is not getting charged.
Someone would need to check for a short in the wiring between the alternator and the battery.

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.

Hi there.
You must have a drain some where.
Make sure the brake light are NOT staying on. if they are, it will drain the battery. this is due to faulty brake light switch.
I think the ESP light is related to the brake light switch.

The power loss light goes on as a result of the alternator being bad.
Are you getting 'lifetime' guaranteed rebuilt alternators to replace the old ones?
If not, then the quality of the parts may not be good enough to run in your application.

Are the connections clean and shiny when removed?
