Alternator problem or it's just because it's a dead battry ?

Question

I have a ford taurus 1996 GL, i parked my car with the battery connected for 4 months, when tryed to start the engine, well the battery was dead. So a friend help me out to start the engine. The car started first try no problem. I tought a 30 minutes run will recharge the battry, but not enought to start it back.

When i drive the car, at around 5000 rpm, the light inside the car lower, and at 6000 rpm, the engine cut for a second. For sure the battery don't want to be charged correctly. Maybe it's dead, and i need a new one.

Well, Here is my question

But regarding the engine cut at 6000rpm, do you think it's an alternator problem ? or it's just that the battry is dead.

Any opinion ?

Answer 1

if you are just letting the car run and not driving it the battery will not charge you need to drive it to get a charge on the 96 if you start the car wiyh the car running take the positive cable off the battery if the car stalls out it is your alt if it stays running it is your battery or you can take a screw driver with the car running touch it to the round shaft on the back of the alt. if it sticks like a magnet your alt. is good i dont know where the dirt track guy got his info from but the stock alt will hold just as much rpm as any alt. will it is the amps that make the difference not the rpm's and the reason it cuts at 600you have what they call a rev limiter it is a saftey feature that keeps your engine from blowing

Answer 2

Your engine probably has a built-in governor that keeps you from over-revving and causing serious damage to the engine. Don't understand why you would be driving the car at 5,000 RPM however. That's WAY high. As for your battery, check the cells and make sure they have enough water -- if they don't, get some distilled water and pour it in (any other kind of water could ruin your battery). If the battery is OK, you should be able to jump-start the car and the battery will hold a charge after 45-60 minutes worth of driving -- it'll take a little longer since the car sat so long. If that doesn't do the trick, you'll need a new battery.

Answer 3

First of all, you should have removed the battery and charged it instead of using the alternator. This forces the alternator to put out the maximum amount of amps.This shortens the life of the alternator, and can also burn it out. Your alternator runs the vehicles electrical system, and maintains the battery. The battery does only three things. It is your power source when starting the car, it supplies emergency power for when the draw exceeds the output of the alternator,( or when then alternator fails,) and it stabilizes the voltage at near 12 volts. Either your alternator has died, or the battery has died. Take the battery out and have it tested. It might only need to be charged for everything to get back to normal. If it has joined that great voltage spike in the sky, then replace it. Then have the alternator checked, just in case. A fully charged battery has to have at least 12.5 volt minimum, (each cells actual full charge is around 1.2 volts, so 12.5 is 90 to 95% charge.) An alternator has to put out between 13.2 volts and 16.2 volts just to run the electrical system and maintain your battery. Anything over 16.2 and it's overcharging, and anything below, the alternator isn't putting out enough. Do not, under any circumstances, ever dissconnect the battery while the engine is running. This creates a voltage spike and can burn out the alternator, computer, and most of the wiring. One of my employees nieghbors did that after he warned them not too and caused over $1600.00 damage to the electrical systemof their vehicle.That only works on pre computerised vehicles.

Sounds to me like you've were given a parasitic draw someplace on your electric powered gadget. First close off all the vehicle's lighting fixtures and upload-ons then close all the doors. With the battery contained in the vehicle, first get rid of the adverse battery terminal. Now, making use of a multimeter set to the DC volts scale placed one probe on the adverse terminal of the battery and the different probe to floor. study the meter. in case you study better than about 1 / 4 of a volt, you've a draw someplace. Troubleshoot the draw by ability of having someone get rid of fuses one after the different till you note the meter voltage drop. once you note the voltage drop, you’ve discovered the circuit in which you've a attainable drain. thoroughly study that circuit, section by ability of section, till you locate the rationalization behind the voltage drop. Isolate and fix the precedence. If this does no longer restoration the precedence, take better take care of a few days and note that each man or woman the lighting fixtures are off till now you walk faraway from the vehicle for the nighttime. it may be something so easy as a door that hasn't closed completely, causing an interior gentle to stay on in one day or maybe a foul turn on an lower than hood or trunk gentle. Any of those are better than sufficient to do the interest. i have carried out it myself, better than once. many times, an complete battery can charge will guard it. Even a bounce start up and operating the vehicle for an hour or so could construct your battery up sufficient to get you going again see you later as your alternator is doing its interest. There are diverse techniques that receives you the answer you want, it truly is in easy words between the techniques to finish the same difficulty.

Answer 5

Sounds like the alternator may be starting to go and the battery is pretty much junk. A battery that get run down to nothing will never hold a decent charge afterwards. It is not healthy to be running a stock alternator at those RPMs.

Answer 6

hi,
the problem u asked for (6000rpm miss)is mainly related wit carburation. u said ur car was parked for abt 4 months. but as its running its fine but do get it checked.ur cars altornator seems to be fine check the battery voltage on a multimeter(if u have one) it should not be below 7.62v if it is its dead. if it is showing above 8-9-10V short both the terminals and again check if the original voltage returns in abt 30-40 sec its ok. just charge it.also check the altornator out put at the terminals that are connected to the battery if the give a output of 10-13 v ur altornator is ok.

Answer 7

My guess is the battary is not holding a charge. The easiest way to test teh altinator is to start teh car turn on the lights and stereo then disconnect the battery if the altinator is workign the car will stay on. If you have a multimeter check the charge across the battery terminal while the car is under heavy electrical load you shoudl be reading about 12 to 14 volts.

Answer 8

Battery is dead. The car would not run if the alternator and battery are bad. If you have a dead battery draw to long on your alternator you will overload it and it will need replacing also. Get a battery ASAP.

Answer 9

When a battery sits in a discharged state for any length of time, it can build up a slug from the chemical breakdown which can cause a short in the battery. If your alt. is putting out 13.8-14.2 volts while the car is running then you probably don't have a alt. problem unless you have an excessive amount of bearing noise/slop from that alt.
