Do you have to jump car after replacing alternator?
Replacing the alternator does not create a jump-start opportunity. If you need to jump-start the car, the alternator work is not the cause.
How to jump start a car with a bad alternator?
You will need another car with a good battery. Connect the positive (red) cable of the jumper cables to the positive terminal of your car. The other red cable on the opposite end of the jumper cables should go to the positive terminal of the other car with the good battery.
Why does my car not start with a new battery and alternator?
With a new starter, battery, and alternator (assuming you have not drained the battery attempting to start it), the starter should attempt to crank over the engine. If the starter does not make any noise when the key it turned to crank over the engine, you have an issue with the fuses, or the circuit.
When is it time to replace your alternator?
Your alternator needs to know when each one of those things is plugged in and turned on, so that it can increase power. More importantly, just like with your breathing, your alternator needs to know when to put out less power.
Why is my alternator going over 14.8 volts?

Why does my car not start when I jump the alternator?
If jump starting gets your engine started and running, but the car will not start again once you turn it off, the battery is probably the problem. In this case, the alternator is doing its job of keeping the battery going once it has been jumped, but the battery can’t hold a charge when the alternator is shuts off.
Where do you put the jumper cable on a bad alternator?
The other red cable on the opposite end of the jumper cables should go to the positive terminal of the other car with the good battery. The negative (black) cable should go to the negative terminal of the good battery. Place the negative cable of the car with the bad alternator on the engine.
When to replace battery, alternator, or starter?
When you check these three, always start with the battery. It’s most often the part that failed, and it’s also the cheapest part to replace. A car battery should last about four to five years. It is not made to hold a charge for that long, so it gets recharged by the car’s alternator while you drive.
What to do if your alternator goes bad?
If the engine dies, that indicates that the alternator is malfunctioning. This is because much of the car’s electrical power comes from the alternator while the car is running. Take the car immediately to an auto parts store.
