Possibly a bad connection between the alternator and battrie. use a volt meter. put one lead on the possitive post of the battrie and one lead on the alternator b+ terminal. run the engine, put the fan on and lights on. the meter should not read above .02v roughly. if it does theres a problem with the cable or connections. do the same on the ground circuit. or use jupper cables between the alternator and battrie.

Your Chevy s10 battery light came on but it gits 12 amps of power is this enough or should you look at replacing alternator?
That's not 12 amps,that's 12 volts,which means the system isn't charging Measure the voltage across the battery terminals,if its charging properly,it will be between 13.8 and 14.7 volts,anything less and its not charging. Suspect then a faulty alternator or wiring problem. and have the battery properly recharged and tested too,a low battery will not give you a correct charging reading and a faulty alternator can take its toll on a battery.
Why does the battery light go on in a 1997 Ford Taurus station wagon when a rebuilt alternator has recently been installed and the battery was replaced less than a year ago?
Could be a bad signal sent by the computer or the alternator is not charging to full capacity. Have someone check the charging amps on the alternator.
Can a faulty computer cause low cold cranking amps in your 1999 dodge avenger?
The computer controls the alternator. If the charging system is malfunctioning, that could be the cause of the weak battery.The computer controls the alternator. If the charging system is malfunctioning, that could be the cause of the weak battery.
How do you check your charging system on a 95 aurora?
I take usually it to O'Reilly or Autozone and they do it for free. If my car won't move, I have a battery/alternator tester (which only shows if the alternator is putting out a good amount of voltage/amps).
When charging a battery at say 2 amps is it a cumulative charge over time or will the battery only receive a 2 amp charge?
Charging a battery at 2 amps means it will receive a constant current of 2 amps over time. The charge is not cumulative, as the battery will only receive a 2 amp charge until it reaches full capacity or charging stops.
You have a 1991 ford explorer my battery idiot light just came on and the amps gauge is showing 10 amps the car starts and ruNsbut the ac doesnt work is this related what do you do?
the ac could be related and if the battery light is on it means that your alternator is not charging properly which in turn could stop your ac from working due to lack of power I would change my alternator and see if that fixes your problem.
Battery is fine but cold cranking amps are low and car hesitates when cranking?
check battery and alternator
Why is my alternator wire to battery melted in half at the alternator?
There must be too much amperage going through the wire. Either it's the wrong gauge wire (unlikely), or there is a problem where the charging system is putting out too many volts/amps. Check it with a multimeter.
Why when you start your 1995 neon the battery light is on after a little bit it goes off and then comes on again?
Drive to your nearest Auto Parts store and have them check your charging system. sounds like your alternator may be going bad. Check to make sure it is charging right. The alternator needs to put out atleast 14 amps to suffice for the engine to run properly. Might have a bad alternator.
HOW MANY AMPS WILL A AUTO ALTERNATOR INVERT TO 120 VOLTS AC?
The inverter isn't run off the alternator... it's run off the battery. The alternator simply recharges the battery.
Can a battery with to many cold cranking amps burn up an alternator in a 2001 vw bug?
"Big" Battery Damage Alternator?No, it should not damage the alternator. If this has happened it's probable that the problem is somewhere in the wiring circuit connected to the battery and alternator.
How does an alternator produce different amps?
It depends on the load and the voltage. In an automobile, a battery will typically have a voltage of about 12 Volts. If the engine is not running and you turn on the lights, the lights will start drawing current from the battery and the voltage will drop by a volt or so, depending on how strong a charge the battery has. An alternator will produce in the neighborhood of 15 Volts. If it is trying to push current into a system with a fully charged battery, it will only be able to push a few amps. If the voltage in the battery drops, the alternator will be able to push more amps. A completely dead battery will draw the most current (amps).
