Remove the Negative (black) battery terminal while the vehicle is running and if the vehicle dies then it's the alternator, if it stays running then it's the battery. Although this method isn't guaranteed it's usually accurate. DO NOT REMOVE THE POSITIVE terminal (red) from the battery while it's running. It could cause a spark and make the battery explode. Another way is to drive to Autozone or Advanced Auto and ask them to test it… Read More
Disconnect the negative terminal of the battery Leave it disconnected for an hour. (The amount of time it takes to replace the battery). Reconnect the negative terminal of the battery. This works because a transient (voltage spike, noise) is generated when the terminal is reconnected. This is not necessary when the battery is replaced because the negative terminal is normally the last connected. However, when a car's battery dies in storage for example and is… Read More

Have you checked the alternator? Read More
The battery does not have sufficient voltage to start the car when it's cold. Have the battery checked out. If it still goes click click after running the car for a while, have the alternator checked also. A bad battery will not hold a charge and a bad alternator will not recharge the battery, (That is the reason to have the battery checked first). Make sure the connections at the battery are clean and tight. Read More
How do you disconnect power to the battery on a 99 Plymouth Breeze 2.4 so you can connect things to the terminals?
Power does not go to the battery, it comes from the battery, except when the car is running. At that time power does go to the battery from the alternator. Disconnect the + battery terminal. Read More

Dodge Durango 2000 8 cylinder battery not accepting charge will only run if connected to running vehicle alternator tested good any ideas?
Has the battery been tested, does the alternator on the Durango try to charge?... If the truck runs with the battery but the battery doesn't take or hold a charge, it has to be the battery being bad or extremely bad terminals so that the charge can't reach the battery. Age of the battery doesn't matter, a fairly new one can still go bad. Read More
Something is discharging the battery when it is not running. Have the electrical system checked. Read More
It may need replacing or it can be the alternator is overcharging the battery. Have the charging system checked out. The alternator should output from 13.5 to 15.5 volts with the engine running at idle. Read More

Sounds like the alternator isn't working at all. Have it checked. Good Luck!! Read More
The battery light indicates the system is not charging. Have the charging system checked. If the alternator is not charging, the engine will quit running and leave you stranded. Read More
Why are you disconnecting the battery with the engine running? Never mind, you've probably already figured this out by now, but there's a good chance your alternator is fried and your spark plugs are running on battery power. Get your alternator checked out. New ones aren't that expensive (approx. $50) and can be changed by anyone handy with tools. Read More
Have someone park their car nose to nose o along side the Audi. With their car running, attach the red clamp to the positive terminal of the Audi battery and the corresponding red clamp to the positive terminal of their carâ??s battery. Then attach the black clamp to the negative terminals on both vehicles. Read More
put a voltmeter on the battery and test voltage, then start the cycle and check again. A battery at rest should be at about 13 volts, with the engine running it will be at 14 or above. to be sure disconnect the positive battery terminal while running, if there is still good volts there, or the engine does not die it is ok. Read More
I recently installed a new stereo system into my car now my car sounds like my battery is weak is it my battery that I have to change or my alternator?
Check the battery with a vom meter while the engine is running. It should read about 14.5 volts and if so the alternator is working, than have the battery checked Now if the meter does not read 14.5 volts, have the battery, and the alternator checked. If they both check out okay, the problem is in the battery or the alternator circuit on the vehicle. Read More

the battery might be running down have it checked or check the hood yourself Read More
I would suspect a bad alternator and battery, have them both checked at the parts store. A car with a fully charged battery and a bad alternator will run until the battery is drained and then quit. Read More
I'd check your alternator. Disconnecting the positive terminal while the engine is running will tell you. If the engine dies when you disconnect the battery, it's your alternator. If it keeps running it's something else, like your battery. I had the same problem. Read More
I have a 1995 5 liter mustang that just shuts off while driving and then turns back on as you drive?

it should be your starter solenoid. Your positive terminal on your battery will have one wire running from the battery to a terminal on the solenoid. (there might also be a few more smaller wires leading to that terminal from under the engine) Another wire should be leading from the opposite terminal on the solenoid directly to your starter. There will also be one or two smaller terminals on the front (one labeled "s" and… Read More
What would dodge durango keep going dead and have too high of a voltage when put on a tester replaced the battery still drawing to high of voltage and battery dead?
With the engine running you should read 13.5 to 15.5 Volts DC at the battery posts. A reading much higher than this indicates the voltage regulator in the alternator is defective. Read More
There are a number of ways to test an alternator, 1,Set your voltmeter to DC most preferable set the meter to 20volts.2,with the engine running, disconnect one of the battery terminals from the battery head. 2,connect the voltmeter to the battery terminal wires and take your reading. Read More
unplug the negative battery terminal while the vehicle is still running.......if it dies, then more than likely the alternator is bad. if it still runs then the alternator is prolly still good That procedure can damage today's alternators. Better off using a voltmeter and test battery voltage at the battery before you start vehicle then again after it is running. A fully charged battery should read 12.68 Volts and if the charging system is healthy… Read More

93 xj6 and it have been in storage for about 18 months now I tried getting a boost starting it but only got clinking noise Any suggestions?
When a battery is slowly drained over a long period such as by a stereo memory or a clock,a type of corrosion accumilates between the battery post and the terminals that will diminish the voltage carrying ability of the wire, and your battery is probably bad as well. Before buying a new one have it checked for voltage and draw. Before reinstalling it clean the inside of the battery terminal connectors and the battery posts… Read More
If the gauge is showing less than 13 volts with the engine running, then the alternator is more than likely defective. Have the system checked at your local auto parts store. Read More

You have a dead battery and need a jump start. There is the right way and the wrong way to accomplish a jump start safely. Because of the potentially severe hazards due to improper use of jumper cables it must be done correctly. Auto batteries contain Sulphuric Acid which can blind you, or at the very least burn your skin. Also auto batteries vent off Hydrogen Gas which is highly explosive even from the slightest… Read More
Nothing, if the alternator is good the engine should keep running.On the other hand if the alternator is bad the engine will die/stall. In a modern car with sophisticated controllers (ECM, BCM, TCM, etc.), NEVER DISCONNECT the battery with engine running. These controllers have semiconductor chips that are sensitive to voltage spikes and transients which become pronounced when battery is disconnected.. Even the power diodes in the alternator can be stressed and eventually damaged. Read More
A battery is used to start a car. Once it is running, the alternator then supplies electrical energy to charge the battery as well as power the electrical systems in the car. Removing the battery while the car is running will not affect the running of the car. Read More
