SOURCE: new battery and alternator. Battery still won't hold charge

Check all your fuses if you had a system failure it could have blown a fuse. I am not sure on your vehicle where the fuse is in the car or under the hood it could also have a relay. You can check your alternator by checking the voltage at the back of the alternator where the big wire bolts on. You should have 14+ volts at the alternator.

SOURCE: battery not charging light comes on. new battery

I don't know what kink of car you have, but some will have a alternator fuse, also with a volt meter check voltage on big wire at back of alternator should have 13.5 + volt's, then check voltage at battery should have same voltage there also, do this with car running, if you do not have same voltage at battery less short between alternator and battery or bad fuse. There also some fuse links at starter on some car's.

1996 Aurora with intermittent charging issues. New alternator and battery.


Are you aware that this charging system is computer controlled ? There is also a temp sensor for the battery > Battery Thermistor
In addition to the voltage regulator the charging system also utilizes a battery thermistor, which measures battery temperature, in order to control system voltage. A procedure for replacement of the battery thermistor can be found in this section.

2012 Grand Caravan. How do I turn the battery light off after installing a new battery?


Test the alternator. The battery light is for the charging system. Once the charging system is working with the engine running, the light should go off. If your light stays on with engine running, the alternator may need service or replacement.

To test the charging system, just put a voltmeter on the battery with engine running. The voltmeter should register at least 13.5 volts- alternator is charging. If you only show battery voltage with engine running, like 12.2-12.8 volts, the alternator or charging system is not working. The battery light should be on to signify this.

Is the battery light on the dash board working? If the light does not work the alternator will not charge, it needs the power from the light to energise the rotor.

71 c10 not staying charged... new battery alternator fuses good and new voltage regulator


Maybe it wasn't running long enough to charge up the battery?
Stop trying to jump it, when you are having problems with it dying, take the battery off and have it charged. And/or buy a $20 voltmeter to see what the battery shows. If it says less than 12 volts, it is discharged, and needs charging. A good battery that is not run down should have at least 12.5 volts. A new battery that is charged should have very close to 13 volts, maybe 12.8 volts.
When you have the truck running, check the alternator for charging. You put the voltmeter right on the battery and check it again. This time, with truck running, battery should show at least 13.5 volts. That shows the alternator is working. A good alternator will put out about 13 or 14 volts-the regulator will keep it from going any higher to prevent problems, like a melting battery or electrical parts burning out.
I would say get the charging system working right, then address the problem of dying at stop lights. That could be a carburetor problem, if the alternator is working.

My van looses battery charge. Just put a new alternator, and a new battery in, and now the alternator is not charging the battery . What could the problem be?


Before the alternator was replaced it was important that the charging current was measured with an ammeter to confirm charging.It is possible that the rectifier/regulator to the alternator is faulty.This electronic control unit determines the charging current.Please check this unit in your car for failure.Check this link for tips.

May be bad alternator, or battery. Most auto parts stores can test batteries and alternators for free. Have both checked. If alternator is not charging, a new battery will start great a couple of times, then it's run down and you are back where you began.
