Sounds like alternater. take negative battery cable off while running. if the engine quits, its a bad alternater. when running there should be at least 13.6 to 14.2 at battery if alternater is ok! when off at battery, it shoud be at least 12.6 or better. Good-Day!

2012 Grand Caravan. How do I turn the battery light off after installing a new battery?


Test the alternator. The battery light is for the charging system. Once the charging system is working with the engine running, the light should go off. If your light stays on with engine running, the alternator may need service or replacement.

To test the charging system, just put a voltmeter on the battery with engine running. The voltmeter should register at least 13.5 volts- alternator is charging. If you only show battery voltage with engine running, like 12.2-12.8 volts, the alternator or charging system is not working. The battery light should be on to signify this.

Charged battery light stays on


11v is too low, should be over 13v, check the battery for low water if it's not a sealed one, refill if necessary to bottom of the fill ring, then charge battery. If you have a battery hydrometer tester, all the cells should then test about the same, if not and one or more cells show weak, the battery is shot. If you have no equipment, most chain auto parts stores will test it for you free, if you jump start it, and can get it there, they will also check the charging system, (alternator, belts, etc.)

You can get the battery load tested at just about any parts store. I would have this done. If it checks out good, get the charging system tested, and if that is good, you could possibly have a draw draining your battery when it's not running.

Subaru legacy power lose when switched off. new battery charge rate 14 volt+


The charge rate of 14 volt shows that your alternator is responding as it should and is doing its best to recharge the battery. Even with a fully charged battery if you switch on the power hungry electrical items (main headlights, rear window demist heater etc) you should see the alternator respond by pushing out 14+ volts. A low battery will show about 12.2 volts when disconnected. OK you need to find what is draining your battery when the car is switched off. With the car off disconnect the negative terminal and measure the current flowing between the disconnected cable and the negative terminal, it should very very low, just enough to keep the clock running. If you do have residual current flow, remove and return each fuse one at a time and note each time the current reading. Quite quickly you will be able to isolate the circuit that is causing the drain. Often it is a lighting circuit for an interior light that you cannot see....such as a glove box light not going off when the lid closes or the trunk light staying on. These work by a contact switch being opened by coming into contact with a bracket when shut. If for some reason the bracket gets bent or is dislodged then the light stays on.

My 1994 Nissan Pickup was showing the battery light on and then I was drivving to work with the lights on and it started chugging and then died and would not start. Battery dead


The alternator is not charging,need to replace it,and charge the battery up with a slow charge,,,2 amp,over night a then some,slow charging gets the charge all the way up,and creates a deep charge that will stay,and prolong the battery life.
