just installed buell dual headlights.

took apart my wiring harness and removed all unnecessary wires (at least those i think are useless now).

have an SVS
used to have 2 dual fillament bulbs with 3 wires each (one ground, one low, one high).. i think.

new buell lights have 2 monofilament bulbs with 2 wires each. one should light for low and both for high.

i just cut off the wires going to my old headlight #2
took the 3 wires going to my old headlight #1 and sent the ground to each of the new buell bulbs, then the low beam hot lead to new bulb #1 and the high beam hot lead to new bulb #2.

the i plugged it all in.

low beam works great. one light lights up. when i switch to high beam, i blow the fuse for the high beam circuit and both bulbs go dark.

this is not ideal.

any help??

This may not be what you want ,
but I just spliced the high beam wires to both headlights so they are always on

No real help here other than to confirm your wiring logic is correct.

It sounds like the high (yellow) is shorted to ground somewhere; disconnect it at the bulb and see if the fuse still pops. If not, break out the multimeter. You should see around 2.4 ohms on the (+) side of the bulb. If you're blowing the fuse you'll probably see zero (fuse is rated for 180W max).


Hope that helps...

Good news I think I found your problem!  I believe the Jigsaw in the bottom of the pic you posted had something to do with this issue ;D ;D ;D
Sorry no more help than nc_650, but what did you need the saw for???

ah ha .. this makes a lot of sense.
i think i was an idiot and left my 'customized' wiring harness rather uninsulated and in a giant knot.
i will wrap in tape and retry.

thanks.

had to make a couple brackets out of alumiium stock. i use the jig because i'm lazy and won'y use a hand saw.

i was able to use my new dremmel. that was exciting. it involved steel and sparks! ;D ;D

If you're gonna clean up the wiring anyway, consider heat shrink tubing. It's cheap and easy to work with and will buy a little more weather protection than electrical tape (e-tape also gets pretty nasty as it ages!)

Hey, Mike, if you need to use a multimeter today before I see you, I think mine is in my red toolbox. If not, there's a possibility it's on the disaster that is my desk somewhere, but I'm fairly sure it's in the box.

yellow650- it looks awesome. once its all said and done, let us know how the lighting is.
and somepics showing the bracket design/attachment as well.

if we had karma, you'd be getting an applaud from me right now.

turns out it was shorting in the wiring harness. fixed that.

but now i realize how the stock lighting works. at low beam just the low fillaments in the 2 bulbs are on. at high beam just the high beam fillaments in the 2 bulbs are on.

so.... now when i switch to high beams the left Buell light turns on and the right turns off. kinda sucks.

we came up with a few ideas. one is to connect the two circuit loops (the ones going to left bulb and to right bulb) with a diode. this should make one bulb light up on low and 2 bulbs light up on high.

any one have any experience with diodes? do they make them to handle ~15amps?
