The most important component of an electrical system is the battery. The car starts and stops through the battery. Use the OBD2 Diagnostic tool to check the car and know the problem of car.

change the drive belt and have the voltage regulator in the back of the alternator checked out and also check for any draws on the car anywhere cause this can cause the alternator to over charge trying to keep the battery charged up

SOURCE: I have a toyota corolla and battery is fully charged no power

Sounds like a bad connection with one of the battery cables check the connection to both cables at both ends and I personally would make sure that i cleaned the main engine ground (where the negative wire from battery connects to engine). Good luck!

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 ??.

1996 GMC Yukon will not start after hearing intermittent clicking noise while running


Sounds like you lost the serpentine belt, which runs the alternator. When you heard the ticking sound, did you notice if the battery light came on, Check the belt and fully charge the battery. Do not jump a dead battery. Wear safety glasses when servicing a battery, an explosion and acid hazard exist

My volvo s60 wont turn over but theres power in the battrie


Anything less than 12.6 volts, at the battery---is a battery that needs to be charged

Not going above 12.4 when the engine is running ---would indicate
your alternator isn't working,is that what you were told

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.

The flashing lights seem to be a common issue when the battery charge is low. From your description the battery may need to removed, charged, and tested possibly replaced. If it does require replacement you may want to have the starting /charging system checked. If there is an Autozone,Advanced Auto,or O'reilly's available in your area they will typically check this system out for you at no charge.

How will your car run if the battery is not fully charged


If your alternator/electrical system is 100%, it will run normally and charge the battery as it runs. If the electrical system has a problem and the is not 13volts available as you drive, it can cause a loss of power, or stop all together, or missfire or burn up electrical componets. Low voltage is bad.

Several secondary electrical systems not working -- 1998 CLK


They can check the battery and the charging system for starters. Fully charged battery,clean cables. then do a load test on the battery. If it didn't pass the test replace it and check the charging system.
Charging system easy to check , Put voltmeter on battery terminals and monitor vehicle's voltage with and wthout accessories on. should be between 13.5 to 14.5v . Before condemning alternator inspect wiring behind alternator ...if corroded replace then retest.
If voltage is with range then the problem is in the power distribution compartment/ relay, or either is a ground all those items share.
