Alternator and battery replaced on a 2000 kia why is check engine light on whenit wasn't before?

Engine staled while driving and the battery light came on then went off and then your check engine light is on would it be my alternator or battery that needs to be replaced?

your Alternator

Will battery recharge after bad alernator is replaced?

An alternator is designed to keep a fully charged battery at peak level. It is not designed to charge a dead battery. Installing a new alternator on a car with a dead battery can in some cases ruin the new alternator. Fully charge the dead battery before starting the engine.

What should you do if battery was not charged before installing new alternator?

My advice is to charge the battery with a battery charger before starting the engine. You will be putting a heavy load on the alternator if you allow it to charge a dead battery. This could damage the alternator.

Replaced battery and the battery warning stays on?

check the alternator. Use a digital multimeter and with engine running you should have 13-14 volts at the battery. If less than 12.5 Alternator is not charging Also check the amperage the alternator is putting out.

Should your car start right after changing the alternator?

If the battery is fully charged and the starter is working properly it will turn over and start. The alternators sole purpose is to supply voltage to the vehicle and battery when the engine is running. When the engine is not running the alternator has nothing to do with starting the engine. If the alternator went bad and the battery was discharged then you will have to charge the battery before it will be able to start the engine. Do not jump start the engine with a dead battery if you can avoid it. This puts a strain on the alternator trying to recharge a dead battery and can damage the alternator, even a new one.

I have replaced the alternator starter and the solenoid on my 1991 Ford Ranger and when you disconnect the battery cable it kills the engine. What else can be wrong?

Never disconnect a battery while an engine is running!

How do you know if it is the alternator that needs to be replaced?

Check the voltage at the battery with engine running. It should read 13.5 to 15.5 volts. Any less and the alternator is suspect.

Does the motor charge the battery when you run the engine?

No, the alternator recharges the battery. Of course the alternator is turned by the engine.

Mazda mx3 1994 4 cylinder your battery light is coming on along with engine electrical light sometimes you replaced the battery and the battery light still comes on sometimes along with the engine ele?

Alternator

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 do you get the alternator to turn over?

The alternator is run by a belt connected to the engine. When the engine is running the alternator is turning. The alternator is what produces the electrical current that charges the battery & powers everything electrical while the engine is running. the battery is mainly to start the engine.

What is wrong if the battery light is on in a 1999 Ford Expedition and it has 11.5 volts at battery and you replaced the alternator and it dies if the battery cable is pulled while running?

Check out the battery cables. Make sure that they are connected good and not corroded or damaged. Also check the connections at the alternator. I had a 97 Expedition with a battery indicator, 12.4 volts at the battery with the engine off and 11.6v with the engine running. Replaced the alternator and then had 11.9 v with the engine running. Checked the alternator fuses on the firewall and found the 175a alternator output fuse blown. Replaced the fuse and voltage then read 14.3 with the engine running. Not sure if the fuse was blown before the alternator was replaced or not as I never thought a 175a fuse could blow without fireworks. 2 cents: Fuse..... Also check for defective replacement alternator, alternator rebuilt with incorrect regulator, damaged instrument panel cluster, or damaged or poorly connected wiring. Rocky_B Sounds like a dead battery cell. 1) Engine OFF - A servicable battery will show 12.5 volts at the terminals, anything less and you have dead or dying cells - Replace the battery. 2) Engine RUNNING - A good alternator should put out 14volts or more. 13-14volts=weak alternator, If voltage at the terminals is the same or lower after starting, your alternator might not be putting out anything or you have bad diode pairs in the voltage regulator. With most newer models the voltage regulator is attached to the alternator, so you replace both. If the voltage regulator is not attached to the alternator, you still want to replace both as voltage regulators tend to become mated to the old alternator's output over time. replacing just the alternator could cause the voltage regulator to fail.
