If the above good advice doesn't work. Start by disconnecting your battery. Hook a test light(looks like an ice pick with a lamp in the handle)or ampmeter between the bat. cable and battery. Either side will do. Start pulling fuses and watch the light. When it goes out you found the bad circuit. If the light does not go out then you have a current drain in a non fused circuit. You must lift these wires off their lugs and such to test.
