Some cars have an external voltage regulator most alternators have internal voltage regulators if your headlights are dim at warm idle tap the gas and they get brighter the voltage regulator is most likely the problem

Would a weak battery be the cause of a hesitation when turning on ignition?
Could be. But it might be an alternator problem instead of a batery problem. You need a good alternator to keep the bttery recharged. I wouldn't run out and buy a battery without getting the alternator checked.
What cause a 98 Dodge Intrepid that you change the alternator and put a new batery but the batery light still showing and three days later after starting it its automatically died?
Check the electrical connections on the wires. Also, make sure that the new alternator is working. It is possible to get a new one that has problems. You might have to remove it and have it checked out. i have the same problem on my intrepid i changed the alt, batt, and still light on i check both alts and the first and second are good.
Why would battery light remain on after replacing the wires alternator and regulator and the battery is good on your 1989 Taurus?
Sometimes an alternator with a weak diode(s)can test out fine, but can still trigger the light. I believe the problem is in your alternator. Good luck.
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 does the battery light come on the battery and alternator have been checked and are good It's a 2000 dodge intrepid?
The battery light comes on when the alternator is either over or under charging. If the alternator tested good you have a wiring or computer problem. The engine computer is the voltage regulator.
Why would a good alternator not charge a battery?
If the alternator is good and the battery does not charge, then the battery may be bad. There could be problem with the electronics. You will need to take it to a place where they sell batteries. They have equipment to check out the battery and the wiring.
Whats wrong with a car that wont turn over but the starter alternator and battery is good?
The neutral safety switch could be bad or the ignition switch is bad .
93 Ford Aerostar alternator light is on you had the alternator check and it comes out good what else should you check?
There are times when the alternator will test out fine as far as amp output and voltage output but if your alternator has a weak diode(s) it may trigger the light to go on. I hate to say you should replace the alternator, but your charging system is pretty much self contained in your alternator so I believe the problem is in fact in your alternator. Good luck.
Whats the bad points of the three gorges?
IT IS NOT GOOD FOR THE ENVIROMANT and it causes pollution ad sewage problem.
Have a problem starting 1998 Chevy Silverado after running for a half an hour or so - Checked battery which is good - Checked alternator which is good - Can't find the problem?
Perhaps starter is weak. Have it tested for load and drag
If the battery and the starter and the alternator test good why is the power dying?
Either the alternator/regulator has situation dependant problems such as opens with heat or vibrational malfunctions or there is a problem with an internal charging control in the engine computer
PT Cruiser - you had a electrical diognatic test done and now your car is squealing what is that?
You might have a belt problem with the alternator, good luck!
