You have replaced your starter alternator battery and battery cables on your Saturn why is it still losing power?
Voltage Regulator?
How do you know when you need an alternator?
A new battery or one that tested good is in the vehicle and the car is still losing power. the alternator is what charges the battery while the vehicle is operating.
If you have a good alternator in your car why would it still lose power?
Bad battery, Parasitic drain.
Can a car still run if the alternator is dead?
Sorry to say,but no. The alternator is the device that replaces the power that has been used from your battery.Without the alternator, the battery will get drained and not be able to recharge.
Battery has been replaced and alternator is good why does truck still loose power?
Try the cables from your battery and alt. Sometimes these can corrode.
What could cause engine to try shutting down while driving and battery going dead overnight if battery and alternator have been replaced?
Sounds like the engine is using the battery as the source of power instead of using the alternator. The main job of the battery is to give power to the starter that "starts" the engine. Once the engine is started the alternator kicks in to maintain power throughout the vehicle, as well as keeping the battery strong. But if the alternator isn't working, the engine will get it's power from the battery. And without the alternator keeping the battery strong, the battery will die. Note: between the alternator and the battery, there is a voltage regulator, this make sure that the battery only gets the power it needs. Oh, one more note, here's a way to tell if the alternator is working properly. (Start the engine, while it is running remove one of the battery cable for just a few seconds.)if the engine stops, then you have an alternator problem still. Check your wires. Or replace the unit. for more answers. email tjjjlong@aol.com A constant 12 volt drain on the electrical system, even when the car is off
How can a new battery still go flat with new alternator installed?
If you install a new battery & new alternator and the battery runs down overnight then you have something pulling power from the battery. Look for any light on the vehicle that is on or a relay that is stuck.
You replaced your alternator but your car still lost power?
Have the battery checked out. It may have a dead cell and not holding a charge,
Why is a car battery being drained in an 1985 Fiero. A rebuilt alternator has just been installed but the battery is still contueing to be drained?
dead cell in the battery or something is on that is pulling power from the battery.

If the alternator is good then the battery is bad.
Your 1993 Pontiac transport will not charge battery an battery good and battery hand reading nothing with engine running an already had alternator check an replace pcm but there is still no charge?
Does the Alternator have a power supply back from the battery to excite the alternator? I had the same problem and despite trying several alternators found that a fuse had blown on the circuit bring power back from the battery. Or the bushes in the alternator could be worn out or the diode pack could be shot. Put a volt meter onto the small wire on the alternator and across to the vehicle body you should have battery voltage on this terminal.
When you drive your 2000 elantra you notice that smoke comes out of the battery top vent you changed the battery and this is still going on does anyone know what could be the problem?
The alternator is probably over-charging the battery. Replace the alternator if the voltage at the battery terminals is over 15V when the engine is running.
