KTM640 joining hi and low beams
« on: October 24, 2008, 07:07:05 pm »
Hi Guys

I found http://www.advrider.com/forums/showthread.php?t=94226&page=2 on the AdvRider forum and printed it. I went to my bike opened it and now I have a few question.

I have a brown and black wire coming out of the low beam and a brown and blue from my hi beam.

Here's my questions:
Do I put black on 87 and blue on 86.
What do I put on 30?
And where do I put 85?
Where do I put the relay unit?

Thanks
Greg

There are no short cuts to anywhere worth going!
Performance is paramount, niceties only exist if it doesn't affect performance.

Don't rush it, it's helmet time you need, not a destination. Take it easy.

You want to switch them through a relay to have both on at once ?

Be carefull not to fry your regulator/rectifier, it happened to my 640,apparantly the stock regulator cannot handle the amps.

Ok looks like stock you have voltage drop at the light. Had the same issue with my DRZ. Stock wiring seems to thin. So run new thicker cables directly from the battery with a fuse on the positive side. Positive goes from the battery through fuse to point 30 on your relay. Negative goes from battery neg to point 85 on relay. 87 and 86 on the relay goes to the lights positive respectively. Get a multimeter and see which one is positive, but only tee them out ie they must still be connected to the handlebar switch as well. Once you select high beam it will use the power from the battery to power the low beam. If you are not sure let someone assist, you don't want shorted wires and a burnt harness  :P

I would not run two bulbs together. Rather buy a better bulb like a Bosch super silver or the like and use thicker wire directly from the battery (with a relay) if you have voltage drop.

If you want really good lights for riding at night, fit a xenon light, or is it for daytime visibility?

It will be for day time viz. And I think it looks better with both on.

I recently did a Xenon/HID conversion to a 640, and had both being able to run at once, with a switch to use them as normal, but fitting the HID already drops the power consumption, making this type of mod more feasable, and less draw from the current electrical system.
It is a time consuming conversion though, the entire front subframe needs to come off to weld ballast brackets in place.
The bike I did is being prepped to do the Hero's and Legend's Rally next year, same as the Dakar, but not a race.
If you can keep your head in the midst of all this confusion, you don't understand the situation!

I did mine with 3 realys.

I will post a drawing for you before monday.

Basicly I took power from the battery to 2 relays (one hi and one for low), I used the wiring from the handle bar to switch the relay's.. I used the third relay to hold the low beam in when you flick to the hi beam, thus keeping both on.

forgot to add, I run a new power cable from the battery to the realys, and only use the existing wiring to switch the relays, while the lights get full power (12 instead of my measured 10.6v)
