dart hei killing battery

u have a circut that is on, drawing current then. like del said, put a test light in between neg. batt. cable and the post. if it lights up, u have a draw on the battery. start pulling fuses until the light goes off. the circut that shuts the light down has the draw, now determine what part of the circut is pulling the power. of course this test is done w/the key in the off position.
