Ok let see if anyone can figure this problem out for you you have a 1987 F250 with a 460 Im having a problem with it not charging the battery you have all the correct voltage at the battery posts batt?

i have the same problem, i have numerous accessories and a 400 watt sub and amplifier and the only thing i can say that could possibly help is a capacitor, ive also heard of finding a second alternator. my problem is so bad that at a complete stop, with my stereo bumpin my headlights strobe to the bass...lol, kinda cool but it has caused my truck to die multiple time at stop lights.

Battery light on on 2003 Ford Expedition?
Your battery is not being charged because of a problem with the charging system Whether its a problem with the alternator / voltage regulator , the serpentine belt etc . you should have the charging system checked
Your 1986 ford is over charging and blowing up your battery?
would it be my voltage regulator or a wiring problem
What is the problem when your change the alternator and its still not charging the battery?
Obviously check the battery. Anyway, if the alternator, battery, and wires connecting them are good the voltage regulator is next on the list.
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).
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.
Can you charge a 4.2 volt battery with a 4.6 volt charger?
Can You Charge...Yes. As a matter of fact, in order to charge a battery, the charging voltage HAS to be greater than the charged battery's voltage or no current will flow and charging cannot happen.Of course, the charging voltage cannot be excessive, or damage to the battery being charged will result.In your question, 4.6 volts is not excessive for a 4.2 volt battery.
What does AC-DC conversion and battery charging mean?
The voltage in your house is AC. It is in the form of a sine wave that goes positive and negative 60 times a second. To charge a battery you need DC so you do an AC to DC conversion and then apply the DC to the battery charging circuit that applies the correct charging current to the battery and checks on the state of the charge.
What is the maximum charging voltage for a 12-voltage gel cell battery?
15.5 volts maximum.
Why does the battery meter drop when turn on the fan or lights?
all vehicles will drop a certain amount of voltage when accessories are turned on, you need to determine how much voltage is being drawn by using a volt meter, also check charging system and battery condition, if battery is weak or charging system isn't providing enough voltage back to the battery, that can cause your problem and last but not least make sure your battery cables and battery posts are cleanThe battery's charge is low or something is drawing from it.
Can you charge a 12volt battery with a 6volt charger?
NO, a 12 volt battery cannot be charged with a 6 volt charger. To charge any battery, the charging voltage has to be, at least, slightly higher than higher than the voltage of the battery. Current flowing through the battery is what accomplishes the charging, and no current will flow at or below the voltage of the battery to be charged.
Please explain the charging circuit in automobile. 1. How does the charging light comes on when ignition switch is turned on 2. How charging light comes on when alternator is not or less charging?
When the ignition is turned on, battery voltage passes down the wire to the alternator to 'excite' the alternator when the engine starts. When the engine starts and the alternator generates a voltage, the light is extinguised by the charging voltage cancelling out the battery voltage coming down the wire. If and when the alternator completetly fails the the light will come back on as there is no sancelling voltage. if the alternator produces a voltage lower than the voltage from the ignition switch then the battery light will glow.
Is it suitable to apply voltage 12V 30mA to charge 4V 750mA battery?
No, the charging voltage needs to closely match the battery or BOOM!
