Noting, just install it and hook it up.
alternator charging too high need replacing per dealer

you need to replace the alternator
It may need replacing or it can be the alternator is overcharging the battery. Have the charging system checked out. The alternator should output from 13.5 to 15.5 volts with the engine running at idle.
An alternator does not need a gauge to work. It is used to monitor the output of the alternator.
at least 50 A
it doesn't hurt...but you'll also need a yellow top for deep cycle and a high output alternator to handle the load...
You need to replaced the starter or the alternator.
You can do this although,Why would you want to? If you need extra power from the alternator then you can buy an alternator that has a higher output. Some cars do not allow you to upgrade to a higher output alternator though (My Mazda Protege5) In this case things get a little more complicated..... You must customize a mount for the second alternator (I removed my AC pump and put alternator there) This way I did not need another belt etc. Just had to make a custom mounting bracket. Then you will need to wire it up, which would be specific to your application.
Battery may have a dead cell and need replacing.
No, the alternator is the charging device which runs off a belted pulley attached to the motor. The alternator charges the battery which is the source of the current required to get the engine turning over and in turn starting the engine.
Normal voltage will be in the 13.5 to 15 volt range engine running turning about 2,000 rpms. It shouldn't exceed 16 volts or it will boil your battery. If it does not run in this range then you need to replace the voltage regulator. These days that is usually done by replacing the whole alternator as a unit. It is usually the most cost effective method of repair.
