95 Z with LS1 - battery draining I'm posting this about my brother's car. He has a 95 Z28 with a 2000 LS1 in it which runs great and doesn't really have any issues. However if he doesn't drive it for a few days the battery will be completely drained and can't even be jumped off. There's nothing that we can tell that is staying on to drain the battery that we can tell of....Any ideas??

I will tell you a secret for checking for a draw, just don't tell anyone! 
You take a simple 12v test light. Disconnect the negative battery cable. Connect the alligator clip from the light to the removed negative battery cable. Then hook the probe end of the light to the negative battery post. Basically the test light goes inline from the cable to the battery. Make sure the doors are shut and the ignition is off, and RAP is not on. If there is a draw, the light will be illuminated. Then you start pulling fuses until the light goes out. You have then narrowed it down to that circuit. That will make it much easier to figure out the actual problem. Be aware that if you have to check the fusebox in the car, when you open the doors, that will create a draw as well, so pull the dome light fuse, and check that circuit first. Good luck.
