twilight Sentinal URGENT URGENT
Has anyone done the 4.7 Ohm 1/2 watt resistor mod to the twilight Sentinal per QuicksilverC5 post :confused: That was a great DIY post but I am having problems with the $%*@ lights still come on in garage :mad :mad Did per instructions but mine is a 2000 maybe different for that year :confused: Any help :rolleyes: Would be greatly appreciated :D :D :D :cheers:

Re: twilight Sentinal URGENT URGENT (WHY2KRAG)
You could check to see that the resistor is the appropriate power. Check the resistance of the sensor with an ohmmeter and record the value. You'll have to do it in daylight obviously as you'll want to mimic the resistance value of daylight.
I hope this helps. But I thought it was a 10K resistor................

CRUZMISL thanks for the input :D :D I will go and get some resistors from 4.7 to 12K and keep pluggin in :cheers: boys and their toys :cool:

Re: twilight Sentinal URGENT URGENT (Blue Thunder)
The original post was dated or rather a response to Jason Squires from QuicksilverC5 dated 01 may 2001 Title of post re: Twilight Sentinal standard on my Canadian ordered C5- How to turn it off? (Jason Squires) 5:48 PM 8/10/2001 in that reply QuicksilverC5 gave a detailed instruction as to how to do the job correctly. I followed to the letter and nodda nothin worked. :eek: Dave

Re: twilight Sentinal URGENT URGENT (WHY2KRAG)
Did you try the other resistors? How about measuring the resistance of the sensor itself? You did remember to remove the sensor and put the resistor in it's place?(sorry but had to ask)

Sorry to hear that you are having problems. DEFINITELY worked for me.
I'm not sure why (you're having problems) unless:
a) *maybe* years less than 2001 are different/need a different resistor value? (Though I doubt it/would be surprised).
b) are you sure you did the mods to the RIGHT 'sensor' (the one on the LEFT HAND SIDE of the defroster grill)?
c) maybe you have a bad (shorted?) resistor?
As I understand things, the sensor is simply a variable resistor whose value INCREASES the stronger the LIGHT shining on it SO if you can sub in an appropriate (high enough) value resisistor, it's "got to work".
IN FACT: I would think that UNPLUGGING the sensor (infinite resistance) should work, though MAYBE some computer somewhere would get upset and start throwing up some DIC codes/warnings.
Question: I find it hard to believe that you didn't notice ANY difference in the behaviour of your headlights. You've menioned that they still come 'on' in the garage BUT do they GO DOWN in sunlight????
If you've don't see ANY difference, then I think you must have (likely) done something 'really wrong' as otherwise your lights would either want to be always up OR down.
Again - sure you did the right sensor? (LHS of grill)?

Re: twilight Sentinal URGENT URGENT (WHY2KRAG)
I RE-READ your post - you need a 4.7 KOHM (4700 ohms) resistor (1/2 w).
The low value you quoted, if correct, would have essentially NO effect and would explain your problem, although I would think that as I stated in my prior reply, that your headlights should have wound up staying up EVEN outdoors in sunlight. (If you tried that).

Re: twilight Sentinal URGENT URGENT (QuicksilverC5)
I was going to attempt the sensor change out but i was able to find the correct resistor...im heading out of town tomorrow so if i find one, ill do the installation and report back the result. Stay toon! :troll

Re: twilight Sentinal URGENT URGENT (BobG)
I seem to remember reading that Canadian cars do not have the option of turning this off with the DIC.

Re: twilight Sentinal URGENT URGENT (lawdog2k)
I did not see the original post but from what I have read in this one I assume you are trying to put a resistor in place of the sensor to prevent twilight sentinal from turnig on the lights. If that is the case you should also be able to put a 0-5 ohm pot inseries with the sensor then adjust the pot so the lights do not come on untill it is actually dark as opposed to dusk.

Re: twilight Sentinal URGENT URGENT (SoCal C5)
It works just great GREAT GREAT :D GREAT :D GREAT :D :D :D :D :D :D :D No more of those frog eyes comming on while wearing sunglasses :smash: :smash: :smash: I always hated twilight time and pulling the car out of the garage NOT anymore :D :D :D Thanks sooooooooooooooo much to QuicksilverC5 :cheers:
