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.

Should you disconnect your battery if you know the alternator has gone bad?
Only disconnect it when ready to replace the alternator. The primary function of the battery is to store electricity needed to start the car. Secondarily, it stores electricity for use powering the electrical items on the car when the engine is off. If the alternator is not producing sufficient power to run the engine, the battery takes over. Once the battery is drained of its power, the engine will stop. You can jump-start a car whose alternator is faulty but battery is connected, and the car may run for a short time before the battery dies. If there is no battery, the car will start but not stay running once the jump device or cables are disconnected.
