IS THERE A "DRAW" IM MISSING.....PLEASE TELL ME WHAT U THINK. SINCERE THANKS ! CASEY, WASHINGTON STATE.

Answer
Get a good digital multi meter. Hook the Ammeter up in series with the negative post of the battery. With the ignition OFF and all accessories off, it should read no more than 50 mA or .050 Amps. If it's higher, start pulling fuses one at a time until the reading drops. That's where you'll find your drain.
