2003 bmw x5 4.4 battery light stays on

Brother Mark, changing the battery with a new one being done won't make the light go out, as you noticed. Light is still on so you changed the alternator. Good, but the battery light is STILL on. This only means that the charging circuit from the alternator is not working in the voltage regulator or the wiring is not connected properly to the alternator/regulator. A new battery will show over 13 to 13.5 volts not connected. An old battery will still show 12 volts and still be weak or bad. After connected and engine running, the system will show at least 14 volts because alternator/regulator is working properly, using a voltmeter/load tester connected to the battery. If after replacing the battery and alternator it is still reading 12 to 13.5 volts, it is not working and the light will stay lit on the dash. You may have purchased a faulty alternator if the system tests out this way. Have your system checked with a volt meter or load tester bit be sure all the connections are proper and clean.

2000 chevy silverado. alternator problems. start truck and meter shows about 11 to 12 amps for a few minutes then goes up over 14. Did this for several days. today started and went right to 14 amps then...

amps or volts
11 to 12 amps indicates nothing but if it is volts then it indicates that the alternator is not charging the battery
Battery voltage is 12 -13.5 volts and when charging is 14.5-14.8 volts dc
the rest of your statement indicates that the alternator or voltage regulator is faulty and you should have the charging system checked by an accredited auto electrician

Battery keeps going dead. Have had 3 new altanators & 1 new battery. 5 mechanics has worked on it over the last 12 mos.has cost quit a bit of $. but still same thing. Seems to go down when setting over...

Try disconnecting the battery after you park the car in the evening. If there is a short, then the battery should still be good in the morning. if not, the battery is no good. Most common sources of shorts are the alternator ,or the starter. Good luck You take a voltmeter and take a reading across the battery posts. There should be no power on in the vehicle at all...everything turned off and key in the off position. A normal reading may between 12 and 14 volts. Record this reading in a notebook. Now..go pull a fuse in the fuse box. Just one..and go back and take another reading at the voltmeter. Was there any change? No? Pull another fuse. Now you have two fuses out. Take another reading. At some point...that reading will change. It will show an increased reading. You have just found which circuit is causing the drain. With the drain removed the available battery voltage will go up. just follow the affected curcuit, until you find the drain. if alternator curcuit is ok!! then you should have at least 14.2-14.7 volts at battery when running with everything off. good-day ! and good-luck!

2003 chevrolet truck volt gauge reads high

Very common problem with chevey over time the gauge goes bad, but first take it to auto-zone and have the voltage checked if it's 14.5 volts if it is the altanator is most likely ok. You can buy a new gage at any dealer $15.00 and remove the four front bezle ring or beauty ring 4 screws two on top two on bottom. Then pull the plastic cover and pull the volt gage out and push in the new one in it's plase and your done.

Tried to start my 2006 Titan KC and it appeared to "suddenly" have a dead battery. The gauges all went berzerk for about 5 seconds and then appeared to reset with clicking and buzzing under the dash. I...

the battery is only for getting the car started, when it is started the car runs off the altanator, if you were able to jump it and drive home but could not start is again the the battery might have a dead cell. and if you put a volt meter on it it will still read 12.6, but i bet if you put that same volt meter on the battery and turn the lights on it will go below 10 volts, if it does that the battery is no good.

When I start my 2009 Chevy Silverado it shows 15 1/2 volts. Within a few minutes it goes to 12 1/2 volts. Is this normal?

This is normal, My '04 GMC, goes to around 16 at first start-up then drops to 131/2 after it runs a while.

Will not charge

you will get some funny answers from some of these "experts " The symptoms suggest to me with out much doubt that the regulator is not doing its job correctly ,consistently.Iwould take it to an AUTO ELECTRICIAN and get it tested in situ.... there is only 4 things it can be , wireing ---battery---alternator-----regulator and of those the reg. is the only one that chops and changes. it will cost little for a sparky to check the reg ,. AND I WOULD LIKE TO KNOW THE OUTCOME

2006 Chevy Silverado alternator intermittent charging

Perfectly normal.
Starting with the 2005 model year, light duty full size pickups and utilities are equipped with a new Regulated Voltage Control (RVC) system. This system reduces the targeted output of the generator to 12.6-13.1 volts when in "Fuel Economy Mode" to improve fuel economy. The generator may exit "Fuel Economy Mode" if additional voltage is required. This will cause the voltmeter to fluctuate between 12 and 14 volts as opposed to non-regulated systems that usually maintain a more consistent reading of 14 volts. This fluctuation with the RVC system is normal system operation and NO repairs should be attempted.
