i would start by testing the battery , i have seen cases where the battery was good enough to start the vehicle but was causing the alternator to do all the work resulting in premature failure. my f150 went through a brand new ford alternator in 2 months .
As long as the battery is fully charged it will start no matter the condition of the alternator. Eventually the battery will run down if the alternator is not keeping it charged.
Yes, the battery starts the engine, and as long as the battery is fully charged the engine will start. The battery will loose it's charge if the alternator is defective and not replenishing the charge of the battery but the alternator has nothing to do with starting the engine.
It will start if there is enough charge in the battery to turn the engine over. However if the alternator is weak then the battery will not be charged fully.
No, your battery supplies power to the starter. However if your alternator is defective then it will not supply power to the battery and the battery will soon be depleted.

did you unhook the battery before replacing the alternator
the battery job is to start the car so the alternator will kick in after the car is running
Yes it can as long as the battery is charged . The purpose of the alternator is to put the power used back into the battery

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.
the batteries only serve to start the car and the alternator. I'm not sure if it would be your alternator but it's not the battery.
usualy if the alternator is not defective then its the battery. you should start by cleaning the battery post. then you could check the terminal wire that runs from the battery post to the alternator. if thats not it you should check the ground on the alternator.
The answer is no . The battery starts you vehicle , the alternator charges the battery so if your alternator is bad your battery is not receiving a charge which will cause a "no start" condition.
=== === Some types of electrical shorts do cause the battery to discharge. But usually a bad alternator just does not charge the battery. Or does not put a large enough charge back into the battery. This causes the battery to discharge when you start and run the motor. The spark plugs and other things need electricity that would usually come from the alternator is now coming from your battery. If your bad alternator is not recharging the new battery, the battery will soon fail to start or run your vehicle. You need to have your alternator tested. It should be putting out at least 12 volts, usually around 13 to 15 volts.
Make certain the cables from the battery to the starter and the body are good...may be a starter check out your local library for a shop manual and the checks to make.. d
Rather than assume, why not check the alternator? If an alternator is not functioning properly, the battery can only remain fully charged if the alternator replaces the electrical energy that has been used. Test the system to determine if there is an electrical drain, but start with the alternator first.
That could be the alternator or the battery. Try jump starting your car with another car's battery. If it still does not start, it is probably the alternator. If it starts, your battery is dead.
Check for a bad fusable link at alternator
could be the alternator. could be the battery, the alternator charges the battery but does not stop the battery holding a charge.could also be a bad starter motor. take alternator off and have it tested. most places will test for free
As long as the battery is charged
Check your battery and alternator.
YesFirst if the starter is bad the car will not start, if it will not start it can not charge the battery.If the starter will not work it can mean there is an electrical problem that will also prevent the alternator from charging the batteryThe starter itself CAN NOT CAUSE CHARGING PROBLEMS!The extra load on the battery can ruin the battery and that can ruin the alternator. But before that NO.
Possibly a bad alternator. The Alternator charges the battery when the vehicle is running. If the battery is not being charged this could cause the vehicle not to start.
