with ignition switch off, and negative battery cable disconnected at battery, touching it to negative battery post causes sparks; also interior lights are not on at that time.

    What you need is a test light, or even better an amperage meter to see how much of a draw is on the system. Do you have either of these tools?

    Bret is right. Disconnect the battery negative battery connection with an amp meter placed in series between the battery cable and battery terminal, close all the doors, take the keys out of the ignition, remove the fuses one at a time and see when the draw goes away. When the draw goes away you have found the circuit that has the parasitic draw and need to look at each item in those circuits to locate and solve the specific problem.
