viper 5904, viper 530t

Actually it is in the default mode, which according to the manual, is referred to as "Validity", not momentary.  Though that is exactly what it is, momentary.  However the momentary output seems to be a bit too long.

Hi I'm also having the same issue with the 5904 and 530t three separate 5904's all with 530t's all have the same issue sometimes the window cracks sometimes it rolls all the way down have tested the aux outputs in validity mode and the output validity is between 1 to 3 seconds this does not change depending on how long I press the button on the Lcd remote (haven't tried the one way remote yet) spoke to directed and they suggested using a timed output of 1 second but this will void the roll down function all help would be appreciatedI Love This Industry!!

Just a thought to both of the above, ground the vent/down wire, first 4 1 second, then again to make sure the 530t itself is working properly.

Yep tested the 530t to see if it was venting correctly have emailed directed in the states to try to get some help on thisI Love This Industry!!

So I played around with this for a good deal of time.  It seems the newer Viper alarm is sending a signal that is over 1 second long.  And the window control unit wants to see 1 second or less, since this input pulse is not good it gives inconsistent results.  My final workaround was to install a time delay relay on the output pulse of the alarm so i could control or fine tune the output pulse duration.  It has been working with that 100% for 8 months now.

Or turned it into a timed output for 1 second duration.

I tried every output channel and configuration on the Viper alarm and not one would produce a consistent output time.

Figured I'd bump this up instead of a new topic :) For the record I'm having the same issues with the 5904/530t combo, that is, sometimes a momentary AUX push triggers the vent, pause, fully wind down procedure instead if vent only. But I can deal with that. My issue is that auto roll up works fine. Auto vent/wind down via AUX channel works fines (except for one window occasionally). Auto (one touch) up works perfectly fine. Auto (one touch) down works fine on every window except the drivers.. The drivers window has auto up/down built into the switch so you can only interface with the wires after the module. When trying to wind the drivers window down, it stops every 2-3". One touch or hold, it keeps stopping. AUX auto down - it does not stop. Anyone have any thoughts on this? Increasing the resistance settings simply make it stop more often, but then it still winds down fine with the AUX activation...

Hmmm... Something else noteworthy... This does not occur when the alternator is not providing power, ice when the engine is off and the battery is the sole energy source (@ ~11.8v) the down works fine. Once the engine is turned on and the alternator runs (@ ~13.8v +) the drivers window experiences problems.... Any thoughts?
