Keeps quitting I am driving down the road and it keeps quitting, I put a new alternator on it. help

The alternator is the issue, the battery starts the vehicle, when running the alternator run some everything. If the battery is going dead when driving then it's the alternator dying, does the. Battery light come on?

Symptoms of a charging system problem. The charging system comprises the alternator, battery and associated wiring. If the alternator should fail to produce a sufficient or stable enough voltage for the car's electronic systems - due to a wiring short, faulty voltage regulator, or corroded electrical connector, for example - the car will run off the "reserve" in the battery for a short time until the battery is eventually depleted. (The battery itself could also contribute to the problem if it has a faulty cell or for some reason is causing the alternator to put out an excessively high voltage in an attempt to compensate.)

So a couple of quick checks: Measure the battery voltage with the car off. Yours sounds like it will be dead; the clicking while attempting to start is the starter relay not getting enough juice. Then the question becomes: Is the battery dead because of age (fails to hold a charge) or because the alternator isn't charging it? To answer this question, measure the voltage at the battery with the car running. (Jump it or substitute a known good 12V battery.) You should see 14+V. If you only see 12V or less, you're seeing only the current battery charge without any contribution from the alt.

Finally, don't assume because the alt isn't putting out anything the alt is at fault. The wiring harness and electrical connector to the back of the alt should be thoroughly examined. (The wiring connector is a known failure point on early models.) The wiring harness should obviously show no signs of burning, melting or chafing and the battery terminals should be corrosion free and tight. If the harness checks out, remove the alt and have it bench tested. Rebuilding usually gives better long term reliability than chain store bought reman units, I'm told.

Long story short, I suspect the voltage regulator in your alternator failed, the battery gave it's all trying to keep your car running, finally gave up and now you have a dead alt and a dead battery. Don't just install a new battery without doing the alternator voltage output tests.

If you're really lucky it could be as simple as loose or corroded battery terminals.

Have you checked the alternator, I work at a auto parts store and see this all the time, check the inline fuel filter, also have your checked the coil, mine went out and that was the last thing I checked but am back on the road.

The first thing to check is the battery, if the battery is dead try jump starting it with another car or use another battery, if it then starts you should have the alternator tested, most autoparts stores do this at no charge, it may be that the alternator is not keeping the battery charged.

It sounds like the vehicle has stopped charging the battery.Charge your new battery first and see if it starts,or put a volt meter across the 2 teminals and read the voltage ,if it is below 10.6 volts the powertrain control module and the transmission control module will nt funtion due to low voltage.The alternator has an external regulator located in the powertrain control module,which regulates the voltage at 13.6 volts.If this is the case you need to test the alternator.You can take it off and take it to an auto parts store(they will test it at no charge),or you can get a scanner and full field the unit.Start there and let me know because the underhood fuse panel(pdc)could also cause problems.thank you Ramundoo

These are all signs of a bad alternator. The car is running off of only the battery. The alternator charges the battery and keeps the car running. When the alternator quits charging the car will run fine until the battery dies. Then you can jump the battery and charge it, and the car will run fine until all of the electronics and lights run the battery down again.

You have a list of things to look for. If the battery is new, it should turn over the engine, if it is dead, why did it die? Is the alternator charging? Is the battery any good? Did you check the electrolytes? Just because it is new doesn't mean it is good. Then check the terminals, are they clean? A car will not on a dead battery, it will not with battery power only for very long. When you get done with the electrical stuff, move on to the fuel stuff. Is it fuel injected or throttle body? Either way, I would try some fuel additive to clean it up in there. If you get it running. Some of your sensors could be bad. Sometimes the carbon builds up in there and throws the car into a fit, it won't run good at all. Are the dash board lights going crazy? A sign of the alternator going bad.

I would check the cam and crank position sensor, these are definitely the symptoms of a bad crank sensor.

While you are driving, get up to roughly 40 MPH on a road with little or no traffic. Once at this speed, whip the steering wheel left and right as if you were making rapid lane changes. If you notice a change in the pitch or intensity of the sound, it is quite likely that you have a pending wheel bearing failure. The reason that the change will be noticed is because there is a rapid change in load placed on the bearings during lateral moves. Outside of the, the tires alone, can be quite noisy. I drive an old 1981 Mercedes 300TD wagon. I never realized how much road noise was coming from my tires until I replaced them with new ones!

Get someone to change your alternator just a cheap one from the wreckers. or if you don't want it to happen again get a reconditioned one. They are easy to change over.
