Alternator voltage output needs to be tested while under electrical load, turn headlights on - bright, turn heater/AC on high and let engine run awhile .. Using a volt meter for testing > what is the alternator output voltage at the battery terminals? .. Based on your discription it sure seem like the alternator isn't doing it's job .. Intermittent failures are certainly possible... May pass test this time but not the next!

So basically altinator MAY. Be going out is what your getting at ? It probably is I haven't changed it and it's an 02 that's a hell of a alternator if it's NOT. Otw out

I am saying alternators, just like any other part, can fail intermittently under various load conditions and driving environment, like in town with stop and go traffic plus stopping at multiple locations as you stated previously - A weak alternator doesn't charge the battery properly and the battery becomes discharged .. Now, what is the # 1 reason a vehicle needs a jump start? .. Did you see the part I posted about using a volt meter to 'test' alternator output voltage? .. I hope you get it figured out!

Pushrod is right, the charging system needs to be thoroughly tested. We could also use some more information about what is going on when the car fails to start. What accessories are working, or not? Does the clock on the dash reset when this happens? Do your dash warning lights come on like they would normally but the car fails to crank over? Do you hear any sounds when you try to start the car?
All of these questions can point to a particular failure, other than the alternator or battery. We would be happy to take a look at it for you if you would like to call and schedule it in,

When ever I turn the key it just a regular click like the battery died but ain't no way this a fresh new battery after a boost it cranks right up the clock resets and no dash lights except low wash cuz I'm low on windshield fluid I just wondering why it continues to do this early this am I took off the Hotwire n tested the Altinator that wasn't it nor the started I tightened my terminals n it has been cranking right up but I still want know what's going on
What makes me doubt the alternator being bad is that the car will keep running and restart several times. If the alternator wasn’t doing something to charge the battery when you removed the jumper the car would soon die. This is why we need to test, and need more information.
When you say it makes just one click when you try to start it makes me think the starter may be your problem. We see this all the time time on lots of different cars. The test for this is to have someone hold the key to the start position when the car is not starting properly and you lightly tap the starter with a small hammer or wrench. If the car starts when you do this the starter is bad.
