You could have a faulty alternator. There is no reset procedure. What is your voltage reading?

Check charging system message comes up


If a check charging system message comes up then I would suggest you check your charging system... Meaning check to see if your alternator is putting out the right voltage and in most cases that would be about 13.5 volts.

Automobile battery and charging system



Most automobile batteries are lead acid which should have a standing voltage of about 12.6V fully charged at 70 degrees F. To test a battery first it must be fully charged. If fully charged a good battery will stay above 9.5V while cranking engine. Most part stores will charge and test batteries, starters and alternators. To be sure your alternator is properly charging start the engine and turn on the headlights and blower fan to add electrical load. Voltage should be over 13.2V at idle and under 15V with a known good battery. If not check the larger wire bolted to the back of the alternator for loose connection and continuity to the battery. If ok check fuses. If all are present and check good most likely the alternator is bad and needs replacement, although it is possible on many modern automobiles to have a powertrain control module (PCM) be the problem as they serve as the voltage regulator. Most late 90s and newer GM and Chrysler do. If all else fails have a professional check it to be sure. Hopefully this will answer the questions of many. Good luck ??.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

My chevy aveo 2006 model, after having problem with my alternator and replacing it with a new one, the engine lamp suddenly blinked. engine & other power sounds ok. What seem to be the problem


your engine lamp could have blinked for many reasons, as far as your alternator and battery system, make sure the battery is fully charged, when it is, you should get a reading of 12.4 volts, checking it with a volt meter doesn't necessarily mean thats charged fully as far as amps, you should have your battery LOAD tested to make sure it can fully charge and hold that charge, once its charged the alternator should keep it that way , if you test the posts with a meter while the motor is running you should get a reading of anywhere between 13.5 to 14.5 volts, when checking the battery , make sure all connections are clean and tight

I had a the battery light on what does it means


The battery light means your alternator is not charging, so if you continue to drive the vehicle your battery will eventually drain and the vehicle will stop.

You can test this by putting a volt meter across the battery posts. A fully charged battery should read 12.6 volts. Then start the engine and the voltage should increase to 13.5 to 15 volts. If you do not get this increase in voltage, then the alternator is not charging, which can be either the wiring to the alternator or the alternator itself being bad. Good luck :O)

I have a 2000 f 250 superduty I replaced battery and alternator but its still not charging


Check out your main wiring harness from the Alternators' heavy wiring. Some models had a green fuse a foot or two from the Alternator. It may be in a rubber cap like a Marine fitting and it may be blown.

If no success, the electric system is finicky. Although your battery may be new, a fully charged battery is putting out about 13.2 to 13.4 Volts. The Antitheft lockout will interfere with the charging and sometimes the cranking systems.

I have worked on trucks like yours and you need to fully charge the battery before connecting it to your truck. I have jump started similar trucks and they will charge with a jump attached, then stop charging several minutes after the jumper is off. You really need to watch the Volt gauge the first 30-40 miles after replacing the Battery to verify charging.

There is a remote chance that your Ignition switch is not providing current to the Alternator. The Alternator needs current going to the brushes inside. Check for power going to the Alternators plugin on the Alternators' casing with the Ignition switch ON. If it is dead, change the Ignition switch

Thanks for Using Fixya.

I drove it home and it was fine, i shut it off and within five mins i tried to start it and it would crank but wouldnt turn over, i tried a few more times and it nothing, but now my battery is going low...


Hello,

The first and most likely indication of a low battery would be a hard starting problem caused by slow cranking. If the battery seems weak or fails to crank your engine normally, it may be low. To find out, you need to check the battery's "state of charge."
A battery is nothing more than a chemical storage device for holding electrons until they're needed to crank the engine or run the lights or other electrical accessories on your vehicle. Checking the battery's state of charge will tell you how much juice the battery has available for such purposes.
If your battery is low, it needs to be recharged, not only to restore full power, but also to prevent possible damage to the battery. Ordinary automotive lead-acid storage batteries must be kept at or near full charge to keep the cell plates from becoming "sulfated" (a condition that occurs if the battery is run down and left in a discharged condition for more than a few days). As sulfate builds up, it reduces the battery's ability to hold a charge and supply voltage. Eventually the battery becomes useless and must be replaced.

The charge level depends on the concentration of acid inside the battery. The stronger the concentration of acid in the water, the higher the specific gravity of the solution, and the higher the state of charge.
On batteries with removable caps, state of charge can be checked with a "hydrometer." Some hydrometers have a calibrated float to measure the specific gravity of the acid solution while others simply have a number of colored balls. On the kind with a calibrated float, a hydrometer reading of 1.265 (corrected for temperature) indicates a fully charged battery, 1.230 indicates a 75% charge, 1.200 indicates a 50% charge, 1.170 indicates a 25% charge, and 1.140 or less indicates a discharged battery. On the kind that use floating balls, the number of balls that float tells you the approximate level of charge. All balls floating would indicate a fully charged battery, no balls floating would indicate a dead or fully discharged battery.
Some sealed-top batteries have a built-in hydrometer to indicate charge. The charge indicator only reads one cell, but usually shows the average charge for all battery cells. A green dot means the battery is 75% or more charged and is okay for use or further testing. No dot (a dark indicator) means the battery is low and should be recharged before it is returned to service or tested further. A clear or yellow indicator means the level of electrolyte inside has dropped too low, and the battery should be replaced.

On sealed-top batteries that do not have a built-in charge indicator, the state of charge can be determined by checking the battery's base or open circuit voltage with a digital voltmeter or multimeter. This is done by touching the meter leads to the positive and negative battery terminals while the ignition key is off.
A reading of 12.66 volts indicates a fully charged battery; 12.45 volts is 75% charged, 12.24 volts is 50% charged, and 12.06 volts is 25% charged.

In recharging the battery do not attempt to recharge a battery with low (or frozen) electrolyte! Doing so risks blowing up the battery if the hydrogen gas inside is ignited by a spark.
Your charging system should be capable of recharging the battery if it is not fully discharged. Thirty minutes or so of normal driving should be enough.
If your battery is completely dead or extremely low, it should be recharged with a fast or slow charger. This will reduce the risk of overtaxing and damaging your vehicle's charging system. One or both battery cables should be disconnected from the battery prior to charging it with a charger. This will eliminate any risk of damage to your vehicle's electrical system or its onboard electronics.

Take care and good luck

NB: Your alternator might not also be charging the battery while the car is on, so try to check the alternator.

Alternators are pretty rugged, but can succumb to excessive heat and overwork. They can also be damaged by sudden voltage overloads (as when someone attempts to jump start a dead battery and crosses up the jumper connections or if someone disconnects a battery cable from the battery while the engine is running).
Sometimes alternators can partially fail. In the back of every alternator is a "diode trio" that converts the alternators AC (alternating current) output to DC (direct current). If one or more of these diodes fail, the alternator's amperage output will be reduced. It may continue to produce some current, but not enough to keep the battery fully charged -- especially at idle or low speed.
Most service facilities have test equipment that can identify these kind of problems. So if you suspect a weak alternator, you should have it tested to see if it needs replacing.
Most service facilities do not repair or rebuild alternators because it's too time consuming and requires special parts. Most will replace your old unit with a new or remanufactured unit. Your old alternator is usually traded in or exchanged for a credit (so it can be remanufactured and sold to someone else).

We own a 1997 ford f 150 and the charging system is not operating properly. we have replaced the alternator and tested everything in between. please give me some ideas


If you put a rebuilt alternator on the truck - be 100% sure the battery is fully charged before you reinstall it into the truck and this is a MUST. Ford has a problem with their alternators being able to build a low battery. Once the battery is up it is ok. Ask about this at FORD when you call with your VIN #. Take your VIN # down and call the local dealer. Ask about RECALLS for Ignitions and also any other problems.
I have a FORD and had this problem until I charged the battery fully. Also I had my wires soldered rather than just twisted and taped.
There was a RECALL on some of these and a SERVICE BULLETIN on others. Please be sure ALL connections are tight and that the battery is charged and then the Alternator will work properly.

Battery Light is On


The alternator is not charging the battery. Could be alternator, voltage regulator (which is usually in the alternator) , dirty/loose connections. First I would inspect all relevant electrical connections, clean & tighten. If no change -- replace alternator.

But be sure to fully charge the battery before you run the new alternator (follow alternator installation instructions).
