batt drains seemingly at random til car is dead, dead, dead. Can

light showed no parasitic draw with multiple tests over time.
So: I did it differently this time. I hooked the V/O meter up to
check for batt drain and sure enough you could watch it falling off
from 12.5v down to the high 10's low 11's...until I pulled the fuse
for the interior lighting circuit when it stabilized. Further
discovered that if the driver's door is closed (circuit supposedly
open) I get the voltage leak-off. If door is open everythink is OK.
Passenger door switch does not cause same behaviour. Chased wires and
saw that drivers door switch wire(just one) only runs to the passenger
door switch. That is to say that this wire appears to only have 2
points, A and B, and goes nowhere else in the car. This circuit only
seems to connect the two door switches. If true, how the hell does
this circuit operate? I thought I was so close. Help guys! Thanks.
