[DML] Lock Module (was common electrical leak)

["daveswingle2" <dswingle@xxxx>]

NOTE - reference to parts INSIDE the lock module. 

A failure mode (not sure how common) of the lock module (in addition 
to the relays welding themselves together and burning up the 
solenoids) are the 1000uF electrolytic capacitors inside the module. 
If either of these fail short the locks actually still work pretty 
well, but the steady-state current draw of the module goes up enough 
to draw the battery down in a day or so, but NOT enough to blow any 
fuses. 

Disconnecting the large red wire won't help, you would have to unplug 
the multi-conductor plug to avoid this issue.
