Help! Slow Battery Discharge

Disconnect ground terminal of battery. Connect one lead of the meter to the negative terminal on battery, other lead to the ground cable itself. Make sure the red lead on the meter is plugged into the AMP terminal and black lead to black terminal. Turn the dial to the AMP/20A on the meter. That will be your AMP draw. DO NOT ATTEMPT TO START THE CAR, YOU WILL BLOW YOUR METER !!!
