One way to check a drain on the battery is to disconnect the ground cable interrupting the battery's circuit and then hook up a test light between the ground cable to a chassis ground.If the light lights up you have a hot to ground issue.You then go to the fuse box and narrow down which circuit is shorted out by pull fuses one at a time until the test light goes out.

Put the light or meter between the terminal (cable) end that you just removed and the BATTERY POST! If it lights or the meter moves, then a circuit is drawing.

If you connect the light between the cable end and the chassis, nothing will happen.
