Hi. First time post. I've practically given up despite being so close.
I've tried building a relay series to control DRLs on a vehicle that did not come with them factory.
This circuit turns off the appropriate DRL when the turn signal comes on, and turns off both with hazard or headlights.
The problem I am having is that when I turn the signal on in either direction, it's fine. If I flip the signal to the other direction, both left and right turn signals will run. If I turn the signal off and flip it back on in the same direction it will work properly. Again, switch to the other direction and both sides will run.
It makes no damn sense and has probably already confuse me anyone reading this. I may have to make a video.
I know it's definitely my DRL circuit because when I disconnect it the signals work fine.
Note: the combination flasher on this vehicle uses N.O. relay operation, so the turn signal stalk actually removes power to activate the turn signal circuit. There is some resistance in the signal stalk causing a 9v instead of the expected 12v, but that only affects the relay sensitivity and I have switched to 9v relays for this purpose. I am using the "sense" wires direct from the signal stalk and not post-flasher otherwise the DRLs would just flash opposite the turn signals.
Right now I just don't understand where this weird feedback is coming from that causes both turn signals to run unless I select the same signal direction twice. Like, if I do a tap-then-lock on the signal stalk .. no problem.
Any ideas.. Any additional information needed to help me with this?
