Either car can he damaged if the cables are shorted out or reversed. If hooked up properly, damage is very unlikely.
Not if you jump it from the battery or electrical system of another car.
If you do it correctly, no, you will not harm your battery.
clean the battery terminals with baking soda and water. them jump it
your alternator
Damage to the alternatoron both can occur and permanent damage to the batterries also can occur. Always be sure of +positive to +positive and -negative to -negative if unsure do not attempt to jump vehical it can be a costly mistake It can "fry" the alternator, the computers, wiring, fuses, and the battery.
There is a possibility that you burned up a diode plate in your alternator and the battery cannot get re-charged. Check the battery, if it's low you might want to somehow get the vehicle to an auto parts retailer where they can test the electrical system and let you know what's wrong.
Yes, but this is not a good idea as it puts a heavy load on the donor car alternator and may damage it. Use a battery charger to charge the battery.
It sounds like you have a break in the wire which connects your alternator to your battery, get it checked out.
you can but it wont stay running if the battery is dead
Yes, you can charge your jump box by leaving it connected to a running vehicle's battery. The alternator in the running vehicle will provide power to the jump box, allowing it to charge. However, it's important to ensure that the jump box is compatible and can safely handle being charged this way. Always follow the manufacturer's instructions to avoid damage or safety hazards.
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 would expect that the battery is dead; however, instead of jump starting the car, it is far easier on your car's charging system to place a battery charger on it for about 6 hours then start the car. Otherwise, the alternator tries to charge the dead battery at a wide open rate and it can damage your alternator. Mark
