It sounds like the starter is bad. The clicking you hear is the solenoid trying to kick-over the starter.
If the vehicle starts but, won't stay running, it could be the alternator, or the wireing to (from) the battery or alternator (most likely the ground wire). Or it could be the dreaded MASS AIRFLOW SENSOR!!!!
Your alternator is probably rebuilt and not really new. I have had this problem several times and I have bought a new battery and alternator. The alternator keeps your battery charged and powers your electrical system, so even when driving you can lose all power in the car from the alternator draining your battery. Take the battery and alternator to an auto store and they will test both for free. Ask them about the difference in a rebuilt alternator and a brand new one. This is a very common problem.
Test the battery with a digital voltmeter. You should get a reading of 12.6 V if the battery is fully charged. If the battery is fully charged then you know the alternator is functioning properly and your problem is more than likely a defective starter.
I seriously doubt that it's the alternator that's doing the clicking. Most likely it's the starter. Check the battery, a discharged battery can cause that problem. Have the battery charged then start the vehicle and drive it to a shop that can check the charging system. Many auto parts retailers will test the charging system for you.
The problem is probably the alternator. If the alternator fails to keep the battery charged the battery will keep the car running until it can no longer supply voltage to essential systems and the car will stall.
There is no problem...the problem was the alternator. You have fixed the problem.
you may have a bad battery or a bad voltage regulator
check if your battery is low than usual ..might be alternator problem
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
change the battery every time I've had that it's been the battery the likely problem is not the battery but the solenoid that is attached to the starter motor
Something is draining the battery. Check all lights. Glove box, trunk, etc. Also check the power window switch.
Battery, starter, starter relay solonoid, or a charging problem i.e. alternator or voltage regulator causing battery to discharge. Or bad battery cable connection or dirty or loose battery cable connections can cause this problem. Need to investigate & narrow it down.
You have a short - it's hard to be more exact than that, but if you disconnect the battery and charge it outside of the car and it stays charged, you have a short. If it does not stay charged, you need a new battery.
