I have a python 700 along with some after market door locks that randomly unlock immediatly after a lock event in my 2004 Dodge Ram. Basically, I have sit in the parking lot and unlock and lock my car with the alarm until the locks will stay locked. When it happens it's about a 1 sec pause between when I locked and the doors unlock again. The alarm stays armed the entire time.
The locks use a ground pulse to trigger a lock and unlock. I hooked a leg of a normally open relay to ground and the other end to the door lock auxiliary input... And there is a fuse sitting in series between the python relay and the door locks.
Does this sounds like noise or something else? Should I put a capacitor or something else in there? It seems like it worked for a while, (3 or 4 months) before I started having problems.
thanks in advance.
If you have 5 wire motors in both doors, disconnect the ground on the passenger side. 5 wire motors have incorporated micro-switches that trigger the controlling relay and because after-market installs are never as precise as the factory original* one side thinks its locked and the other thinks its stil unlocked hence sending conflicting signals via the switch wires to the relay.
*Actually not particularly true have seen same problem after some years on BMW, Ford, Peugeot/Citroen, and Opel/Vauxhall (EuroGM).
