What is wrong if you get on the gas and your battery gauge goes down?
Sounds like the alternator is going bad, Need to check charging system with a volt meter.
When bad battery cause dc car voltage ok. cause ac volt on car running show what ac volt is ok?
Vehicles run DC. 13.5 - 14+ volts at battery is o/k. Shows alternator is charging but won't tell you amp output. If the battery is bad you will wear out the alternator as it trys to keep a bad battery charged (it will work itself to death)
How do you detect a bad battery on a laptop?
Usually your computer doesn't start or you can see it wherever the battery charging icon if the battery is charging or not.
Your battery goes dead over night its charging 14 3 volts?
A charging voltage of 14.3 volts for a typical lead-acid 12 volt battery is reasonable. The "normal" voltage is 13.8, but anything in a range of 13.5 to 14.5 is OK, depending on temperature. If the battery is going dead over night after having been charged, the either the battery is bad or there is some load on the battery. To check for load, place an ammeter in series with one of the leads. There should be no or little current flow.
How do you know if your alternator is bad on 2001 Chevrolet Tahoe lt?
You need to check the charging system with a volt meter. It should have 13.9 to 14.2 volts at the battery with engine running.
Why isn't your Mazda truck alternator not charging your battery?
bad alternator, bad voltage regulator, bad battery, bad connections.
What causes a truck not turn over Battery is 5 months old?
The most common reason for a vehicle not to turn over is a bad alternator. If the alternator is not charging the battery the engine will not start, regardless of the battery age.
What causes the batter light on a 1996 Plymouth Breeze to stay on?
When the battery light is on all the time then the computer has detected a problem with the charging system. It is either over or under charging. The prblem could be either battery or the alternator\generator. An undercharge condition can also simply be caused by loose\bad battery cables or alternator connections. You should have the code read or have Auto zone or a auto parts store check the battery and alternator for you. Then it can be better narrowed down. If you can and know how to use a digital volt meter you can just check the charge at the battery with the engine running. If the voltage goes over 15.5 volt then the alternator is overcharging and also frying the battery. Replace both. If the voltage drops under 13 volts then the alternator isn't charging properly. I hope this helps you.
Could a bad coil keep the alternator from charging the battery?
Yes, because a bad coil will not allow the engine to run. But if the engine is running then the coil has nothing to do with the alternator charging the battery.
Why wouldn't a riding lawn mower charge the battery?
Possibilities: 1) You have a bad battery. 2) You have a bad ignition switch. 3) You have a broken or unplugged wire to the charging system. 4) You have a bad charging stator.
Would the voltage regulater keep from charging your battery?
The voltage regulator regulates the output of the alternator or generator, depending on what you have. today it is mostly alternators that are regulated to 14.4 volts, but you are fine if it is putting out 13.25-14.9 volts lower than 12.5 volts will not charge a 12 volt battery and over 15 volts will boil or explode the battery. 6 volt systems will usually charge 6.5-7 volts. if the charging system is putting out that voltage, and the battery is still going down first check for bad connections, and charge the battery, if that still does not fix it have the battery checked, most parts stores offer some form of a test for a battery and can lead you closer to the problem if the battery is not the problem.
Is charging an iPod a lot bad for it?
Each ipod's battery will last for a certain number of charges. Charging your ipod touch alot isn't bad, but will cause you to need to replace its battery sooner.
