Low beam just stopped working last night. Of course it was completely dark and I was 25 miles away from home. Just pointed the lights down and rode home with high beams on.
Background: I am running Dual Dominator headlight:
Each side has H4 bulb (both low and high beam). Original Dual Dominator wiring: it only had one three-prong inlet and each of the prongs has 2 wires connected to it. 1 wire goes to left light and 1 wire goes to right light.
I already had BD43's mod done, so I just used my right side 3-prong outlet (3 wires connected and worked on stock setup for both low and high beam). I ran it like this for over a year with no issues.
Now: Low beam does not work on either side. High beam works on both sides.
Here's what I've done so far: pulled both bulbs out and checked them. They're fine. Just in case, plugged another set of bulbs in.. same issue.
Here's where it gets interesting. With both bulbs out, I measured voltage on low beam setting. I'm getting a perfect reading.. 13.6 on both sides. As soon as I plug one bulb in (doesn't matter which side.. I tried both), voltage goes to zero!!
Another thing I noticed which seamed kind of weird to me.. not sure if it's supposed to work like that.. take a look at the picture below:
On low beam setting, 1+2 reads 13.6. 3+2 ALSO reads 13.6, 1+3 reads zero. Could that be normal??
On high beam setting, only 1+3 reads 13.6, all other combinations are zero.
Headlight fuse is fine (obviously). Any idea how I can fix this??
