A bit of an update.
I have two door locks available to test (one I removed following a “machine gun” experience and another that I aim to fit as I can’t get superlock working with the one in the car.
So with the connectors lightly gripped in a workbench I tested for continuity between pins with the door locks available open then closed and locked/unlocked.
What I could not confirm with repeatability was the presence of continuity between the pins associated the micro switch that comes into play when using the key (or the same switch that would be activated when the quadrant is moved electrically).
When testing I felt that sometimes there was continuity and sometimes not.
So perhaps that switch is used to indicate one part of the sequence and if it’s continuity switches on/off that would presumably confuse 5AS and create the “machine gun” condition.
Just a thought even if I can’t see a simple solution
