Re: MORE Theory of operation (was Diode in Lock Module)

["Jim Reeve" <ultra@xxxx>]

Whoa Walt, I've thrown you into what appears to be an endless abyss of 
possiblilites on the operation of the central locking system! And I 
think you may be wrong with your "Lock Door" light theory. (Both of 
them). If you look at the diagram again, you will notice that the 
Lock Doors light recieves positive power (+12V) direct from the car. 
The ground for the light come from the circuit for the unlock sense. 
What this means is that there is a constant ground coming from lock 
switches into the light and then the module when unlocked. Same thing 
happens when locked, but then the light doesn't get a ground because 
the ground is not on the lock sense, therefore it shuts off when 
locked. This is why your lockzilla remote will not work if the doors 
become out of sync, the module is getting a ground for both the lock 
and unlock sense, so it CANNOT be activated again untill one of the 
grounds are terminated, (hense, manually moving one of the locks). 
I'm impressed by your electronics knoledge, but I would have thought 
you would have realized that. It is a pretty screwy system, but 
remember that this is central locking, and not tradtional locking, so 
it needs to be a little different. Good luck with any new theories, 
even though some of that stuff goes right over my head, I do find it 
quite interesting.
