Alternator not charging battery due to a bad fusable link?
disconnecting the battery for a few minutes usually does the trick.
Depends on how low the battery is but give it 10-15 minutes and it will be fully charged, assuming the alternator is working properly.
Yes.Normally, the alternator charges the battery as you drive, and if if doesn't work, the battery never gets charged causing the battery to discharge. A discharged battery will have a short life, and is more likely to freeze in cold weather which ruins the battery completely. Note that an alternator should always be tested hot (within 5 minutes after driving for at least 45 minutes) . A bad alternator with a bad voltage regulator or rectifier diode may test good when cold.In some cases, an alternator may be "bad" because a rectifier diode (internal part like a check valve for electricity) no longer functions. With a bad diode, the alternator can, from time to time, actively discharge the battery when you shut the car off depending on the (effectively random) position at which it stops.
Car batteries get re-charged by the alternator. If your battery recently went dead, "miles" is not what is measured to recharge the battery, "time" is used. I'd leave the car running for 15-30 minutes. Driving for this amount of time too is fine. If the battery goes dead again, probably a bad battery or bad alternator, or sometimes a bad alternator makes the battery go bad and they both need repaired. (typically a new alternator is $120 - $200)
If the remote car starter stopped working after a new battery was installed in the remote, the remote needs to be reprogrammed. If the remote starter stopped working after a new battery was installed in the vehicle, the computer might need to be reset by disconnecting the battery for a few minutes.
Most likely it will not be the alternator. It sounds as though the alternator is working very well. It will be a faulty battery or a battery drain due to something left on or shorted out. Usually a boot light or glovebox light or recently fitted stereo.
There is a good chance that your alternator has stopped working. It could also be just a loose wire from the alternator to the battery that is not letting the battery charge. Also it could be a bad battery. When a cell in a battery dies it will hold a charge for a short period of time but then rapidly die. Get the battery checked first. they the wires, then the alternator.
That will depend on the capacity of the battery and the amount of electrical loads. could be 15 minutes or a couple of hours.
Immediately disconnect cables but leave car running for at least fifteen minutes
a bad alternator or battery or both
The "battery" light indicates a problem with your charging system... So either your alternator or regulator, Battery, ground connection or fuse, check the error codes too
disconnect the battery for ten minutes
