Well, sadly, no luck on the low beam relay. I did a test light with the relay out of the socket and two of them lite up, two of them didn't, so I'm guessing that is good, since it would mean that two are live and two are ground. Also switched the relays around to no avail, troubleshooting if one was bad.
I actually ended up breaking the housing on one taking it out and got a domestic replacement. It was $16 at Advanced Auto. Here is a link to it. Even though it says it doesn't fit, it does...I guess I can't post the link since I'm new...so if you want to know, just message me.
Here is proof:
I did try to jump one of the blinker lights (with a 14 gage wire) and did get a temporary glimmer from the bulb but it faded and then both blinker bulbs wouldn't lite up until I turned the key on and off again.
I haven't yet cleaned off the kill switch and starter side of things. I'm actually curious if that would do anything, as according to the wiring diagram, the only thing they have in common with the headlight is the ground. My thought is that is simply terminates everything that way versus some kind of switch to turn off the headlight. Here is that section of the wiring diagram and does share a Gray ground:
I did my best to trace everything I could for the headlight and where it goes. Here is the wiring diagram and other than the dimmer switch, I'm just plain stuck on where else it could go. Like I said in a previous post, I did clean it. I ended up taking apart the small contact and giving it the wire brush, but I didn't test light it. It appears the wires are covered in some sort of epoxy to help with longevity. On top of which, when I closed it up, it doesn't shut properly...argh...
Here are my traces on a wiring diagram. I had to piece this together in paint because Acrobat is being a jerk. I'm happy to expand this further out:
It seems to go right to that lo beam relay and then to the dimmer, only making a detour to the dash light to tell you that the high beam is on.
Speaking of which, the high beam light on the dash is not coming on. I re-checked the dimmer switch and it's clean and has been taken to the wire brush. So, I'm wondering if it's the dimmer switch itself (although it looks perfectly fine) or it has something to do further with this mystery blue being disconnected somewhere.
At any rate, the mystery continues...I called a shop and left a message and we'll see if they'll take her in. So many places won't, even here near downtown Denver. I'm just afraid this might mean a major tear down and cutting into all this wiring wrap to find the bad lead...sigh.
Anyone know a good aftermarket headlight I could easily wire in in it's place? Honestly, and this is going to sound terrible, but to make it barely legal, I've just strapped a powerful headlamp on the front. It's just enough to see and be seen.
Okay, that's it for now...sun is going down. Tomorrow is another day.
