You might want to post this in the right forum. Like Tech or something.

 

Yeah why did you post it here?

Probably an improper ground.

He said he changed the battery 5 times.

How do you know your alternator is perfectly fine? Check that again, or maybe your voltage regulator

 

Take out a voltmeter and get to work.

 

i check my alternator through microtech and send to battery shop to check as well they told me something is using the battery even when the engine is not running please help me any other possible reasons ? can it be my earth wire

 

If yur alternatr is fine and you know the battery(s) are are fine then as you said you most likely have somthing draining the power

To my knowledge the most common two things to drain power from a car will be an aftermarket amplifier or a car alarm with a backup battery that constantly charges itself.

hope that Helps.

 

how do u know wheter it is the amplifier? How to do a quick check?

 

Disconnect the amp and see if it still has the problem.

I would have said a bad ground of the alternator, but if you have an amp wired incorrectly, it will cause the same thing.
