Hey Guys. An easy way to see if something is draining the battery is to get a cheap multimeter (like the one Harbor Freight sometimes gives away) and measure whether any current (i.e. amps) are being drawn when everything is turned off. All you have to do is disconnect the cable from the battery and then make the connection from the battery to the cable using the multimeter leads. Make sure the multimeter function is set to 10A and make sure the red lead is connected to the "10ADC" input on the meter. You can then measure how much current (up to 10 amps) is being drawn directly on the meter. The only caution is to not turn on any major appliance while you've got things connected this way. But even if you forget and do so and you accidently draw more than 10 amps, it will normally just blow the internal fuse in the multimeter, which is easy enough to replace.
