Mike,
A simple way to check for excessive key off draw is to go to Radio Shack and buy a 1 ohm 10 watt resistor. Disconnect the negative lead and put the resistor in series. Read across the resistor with a high impedance digital volt meter. If you read a voltage drop of more than .05 volts, you have an excessive key off current drain.
