Not enough ground wires
« on: June 02, 2011, 07:28:33 PM »
I feel like I'm taking crazy pills. I have two four socket connectors in the headlight bucket. I have to hook up to them:

Headlight
High beam
Left signal
Right signal
Speedo light
Tach light
2 x ground to headlight bucket
Clutch switch (I think)

Too many things. Have I hooked something up wrong? Is there a secret ground wire I'm missing?

I've hooked my headlight up to the bucket ground before, but I'm not sure if that is "correct".  That could free up some space for you though.

Couldn't see any other ground wires in there. I ended up imagineering a splitter cable, so ground, headlight, and tach are all hooked up.

Okay, first, the headlight only needs one ground for both low and high beam.  Then, the ground wires that go to each side of the H/L bucket ARE the turn signal grounds. The bucket ears are isolated from getting ground from the frame because the rubber grommets.

Not so many, when you look at it this way. ;D

Hm, I'll have to see what's going on in the bucket again. Not sure if I correctly stated all that is connecting to ground.

So, those green wires grounding the headlight bucket are the green wires shown as being connected to the turn signals in the wiring diagram? That confused the heck out of me when I saw it. I only have two wires (orange and orange/white, blue and blue/white) coming from each turn signal. Plugged it all together and it worked anyway.

One more somewhat related question. I noticed a brown/white wire with damaged insulation on it coming from the left hand switch. I meant to cover it in shrink tubing before I shoved it through the new handlebars, but I forgot. What would be the effect of a brown/white wire being connected to ground?
