A few months ago I did the DRL & Twilight bypass, per BackInBlack's schematics ( http://www.backinblackgp.com/DRL_TS_Kill.htm). Thanks again BnB. The DRL bypass worked fine, but the Twilight bypass failed. No matter what I did, the twilight kept the lights on, unless the e-brake was applied or the key was off. I put the wiring back to the way it was and moved on.
I e-mailed BnB and he thought maybe the resistor was wrong, but I triple-checked and it was 1/4 watt, 470 ohm, as instructed.
So, today I finally had some time to pull things apart and see what was going on. My resistor was giving me goofy readings, so I put in a new one that tested fine. I hooked up the wiring to my rocker switch, and the same thing happened; with the rocker switch in the "on" position, the twilight worked normally. But when I moved the switch to the "bypass" position, the twilight stayed on all the time, unless the e-brake was applied or the key was off, just as it did the first time I attempted this mod.
Any thoughts?
The part that confuses me is that I couldn't get a resistance reading from the twilight sensor when I tested it. How is that possible? I tested my rocker switch and it is giving me good readings, so the resistor is doing its job.
I'm thinking that the problem is that I don't get a resistance reading from the twilight sensor, and when in the "bypass" position, my rocker switch is feeding the DRL module 470 ohm, which it doesn't like, so it keeps the lights on all the time. But why?
Help!
