Is the engine turning over, or does the starter just make a clicking noise when you try to start it? You say you just had the battery and alternator replaced. Was this done at a shop somewhere? If so, your best bet is to have them take care of their mess. They should do so at no cost to you, if they are any kind of professionals.

SOURCE: my battery light is on

Sounds like your voltage regulator is acting up, and at times will not let alternator voltage reach the circuit. At this point car stars drawing on battery alone (triggering battery light) and working until it is out of juice. Before you buy a new voltage regulator, make sure that its contact points on the alternator, and the plug from it to the vehicle circuit is clean, shiny and making good contact. These parts, due to their location tend to collect dirt and moisture, leading to an intermittent performance before they stop working completely.

SOURCE: 2001 Merc. Sable headlight replacement

There are two 10 millimeter bolts that must be removed. Place these in your pocket or a convenient place so they will not be mispalced or lost. Also you need to pull upwards and remove an aluminun locking tab(coated in black plastic). After this is done carefully slide assembly foward. Press down on the wiring harness clip to remove it from the headlight bulb assembly, Turn the locking ring on the bulb to the right and remove so you can remove the bulb. Twist bulb out. When replacing new bulb do not touch the glass portion of the bulb. If you do so clean off with alcohol. Oil from your fingers left on the bulb will cause the bulb to overheat and fail prematurely. Replace bulb and secure with locking ring. You may also want to change the yellow parking/signal light bulbs at the same time. Clip wiring harness back on and slide headlightassembly back into place. Slide aluminum locking tab back into place. Now hand thread 10mm bolts back into place, Then tighten, do not over tighten. Now do the other side. First time might take you about 10 minutes per side. After that you could do it in a couple of minutes. Info on performing this maintenence can be foud in the owners guide or by downloading the guide from the following link

Hope this info helped.

SOURCE: 2001 Saturn SC2 Electrical issue

I had the same problem in a 1997 SC2.  Turns out that finicky/broken door lock/unlock switches were causing an intermittent short.
I removed the 20A fuses to these locks in the switch panel under the radio.  Problem fixed.

I have a 2004 kia sorento, just replaced the alternator and the camshaft position sensor. Now wont start but battery strong. What is my problem?

When you replaced these parts, did you disconnect the negative battery cable from the battery? Does the engine turn over but won't start, or does it not even turn over? When ou turn the ignition key to "Start", can you hear a click or an noise? Do you have electrical power to lights, horn, radio, etc.? Sorry for all the questions, but more information is needed. please.

Have a load test done on the battery for a failing cell. Check the condition and tension of the drive belt.. Head lights suggest a failing battery.

What is alternator how can i fix it

The alternator is what charges the battery, which supplies energy for the electrical systems of the vehicle, such as lights and the radio.It is driven by the belt which is driven by the engine. Before replacing the alternator make sure it is the cause of whatever problems you may be having. A sign that the alternator is bad may include the car shutting off while driving and won't start back up (but will start up with a jump).
You can test the charging volts of the alternator to the battery while running also.

Alternator indicator light is on

This warning light comes on when the charging system is NOT producing enough current or voltage to meet your vehicle's electrical needs. The cause may be a failed alternator or generator, a bad battery, a failed voltage regulator (if separate from the alternator), loose or corroded battery cables, or a broken or slipping drive belt. Turn the engine off and check the belt that turns the alternator. Caution: DO NOT get your fingers, clothing or tools near the belt(s) or pulleys while the engine is running.
If the belt appears to be intact and is turning the alternator, start the engine, and turn on the headlights. If the lights are dim, it verifies the charging system is not working -- probably due to a failed alternator, battery or other electrical fault.

Ey sounds like you have a bad alternator so you should test to see if the alternator is still good or bad by let the engine running then pop the hood opened and disconnected the ground cable off from the battery terminal so when you do that and if the engine dies then you have bad alternator but if the engine still running after disconnect then your alternator is still good

Lost all power/electrical when went to restart car, battery fine

I had an old Accord which occasionally wouldn't crank or start, took out the Main Electrics Relay situated up under the dash near the steering wheel, resoldered all the solder joints on started like a rocketship on steroids. Seems the solder joints "evaporate" and "dry out", fresh solder conducts full power.
