I have a 2000 mc ss my battery has been draining overnight. Has been pulling the radio/amp fuse lately and the battery has not dying. Use a multimeter and read out a 1.50 amp drainage with the radio/amp fuse in. When i pull it out i get a 0.5/0.6 amp drainage. i was told that it would be the factory amp, but just recently replaced it with another factory amp. Do anyone know of the radio causing this problem?

 

somethings keeping something on, youre srue it was the amps circuit that was doing the drawing? you certainly sound like somebody who can troubleshoot this. i have some diagrams for some stuff in my car but i think its only lighting circuits i'll get ya a picture later.

 

Thanks for the reply, but yea i have been doing some trouble shooting myself. So here is what i have done,because i know its coming from either the radio or amp, i would leave the fuse in alone with the amp and do a meter test and it would come out around 0.5/0.6 amps draw. When i reverse it with the radio in and fuse i get around 1.5 amps draw. With both and the fuse i get about 1.7 amp draw. And that 1.7 amp draw i am not sure if that is a normal draw because of the radio memory and the security o the radio and the other functions of the radio.
