What would cause your battery to drain if you give just a little gas and then let off keep giving it gas and it stays charged when the battery alternator fuel pump plugs wires ignition coils all ok?

short to ground, massive parasitic load. either of these would do it.

How alternator works when the ignition key is on?
With just the key on, the alternator does nothing. With the engine running, a belt drives a pulley on the alternator. Giving the simplest explanation, that pulley is connected to a rod which turns magnets inside a field of copper wiring. That produces electricity. That electricity is alternating current. So it then goes through a diode which converts it to direct current. Then it goes through the voltage regulator, which ensures that your car's battery doesn't get cooked from overcharging. The alternator keeps the battery charged, and that supplies electrical power to vehicle systems.
How do truck battery and alternator work in giving electri power to home?
No battery is 12v alternator charges the battery your hous is 120ac voltage. Would be very in efficient to use a battery and inverter to provide power to a home.
How do batteries to produce hydrogen gas?
similar to separating the oxygen and hydrogen in water. When the battery fully charged it is made up of 64% water and 36% sulfuric acid and when the battery is in "charging" state by the alternator or charging source the electricity basically separates the water molecules (hydrogen from oxygen) giving of the hydrogen as bubbles.....sKD
Why would your car die shortly after giving someone else a jump start?
There is a possibility that you burned up a diode plate in your alternator and the battery cannot get re-charged. Check the battery, if it's low you might want to somehow get the vehicle to an auto parts retailer where they can test the electrical system and let you know what's wrong.
Why would the battery in a VW Jetta not be getting any charge if it has been replaced but you still have the same problem?
You need to check if the ALTERNATOR is giving the correct output so as to charge the battery. By having a volt meter across the batery terminals one can then rev the engine and the voltage accross the battery should be about 13.8 volt indicating that the Alternator is charging the battery. If this 12 volt bateery voltage does not increase, this indicates a charging problem (mostly with the alternator either the brushes or one of the diodes in the alternator).
Could the problem be your alternator or the battery when the check gauge engine light comes on while the battery gauge keeps moving.?
that depends on what your voltage gages says while the car is running. while the alternator is spinning, it should generate 13 to 18 volts. if that's the case, your alternator is fine. If not, you need to replace it. it won't charge the battery, giving you about 20 minutes of drive time, but the more you drive the battery like that, the more you will stress it out. if you stress the battery too much, it may go bad on you too. you can get the battery and alternator tested at most auto parts stores. many stores will even test your parts for free.
A few days ago my 93 caravan refused to start only giving a brief buzz when the key was turned and refusing to crank?
Probably a low battery (either bad battery or alternator isn't recharging the battery) or a corroded batery terminal.
How come headligths dim down when pressing window button?
Your headlights dim because when you press the window switch the charge in your battery is now being used up by more things. Mostly your car should not do this while running because the alternator in your car is giving the battery a constant charge. You might want to check your battery or the alternator. Most auto parts stores can check your alternator for free if you take it off and bring it to them.
What is wrong with your car it only clicks a lot when trying to start but does start with a jump?
clean the battery terminals with baking soda and water. them jump it
Why might a 1984 Nissan Quest battery be discharging if not driven for two or more days in the winter?
You might have loose connections or low cells on your battery. Check the cells on the battery and if they are low fill them with distilled water only. Also make sure your alternator is giving the battery a good charge.
What would cause a good battery to not stay charged on a 1999 Ford Escort ZX2?
have the following checked: do a battery test to verify that the battery is good. do an alternator test, depending on the vehicle, it should show 14+ volts output, and have normal diode ripple. make sure the starter selenoid is good, sometimes a faulty selenoid will draw power. there may be a parasitic draw on the battery, have an auto electric shop trace the problem. == answer== check battery. if battery is poor replace also check starter. little known fact in fords that a bad starter will bleed and drain a battery giving bad indication that the battery is not good
If an 88 Accord DX has a new battery but will not hold a charge do the battery cables need replacing?
A bad alternator will run down the battery. Maybe. Lets check the simple stuff first.How do you know that it IS charging in the first place? Get a voltmeter (VOM) and measure the voltage of the battery when the car is off. It should be more than 11.5 Volts. (Or it is really discharged battery). The start the car and measure the voltage again. It sould be at least 13.5 Volts up to about 14.5 volts. If not then the alternator is not giving enough voltage to charge. If it is, then it could still be a diode in the alternator that is bad. You cold have some accessory or light that stays ON somwhere draining the battery. It could be a bad battery. It could be a bad set of battery cables.
