You may have fried a diode in alt. With key off pull battery cablr get a spark? if so something is drawing power. Now remove red batt cable from back of alt. does spark go away from batt cable? If so alt is problem. If this all fails you need to have a battery drain test done to determine source of drain.

i did what you ask me to do i disconnected the red cable of the battery then took the cable of the alternator off and the red cable of the battery still gave a spark so i know now that it isnt the alternator do you know if maybe one of the fuses burned out.

You need to have a battery drain test down to pin point circuirt that is at falt. You have about a mile of wire in car and hundreds of components this test will find the problem. Otherwise your fighting windmills
