Anyone have a Baja Light Kit on their WR400? I just picked up a 98 that needs some attention, but not too much attention...to the extent I took a small chance on the bike.

A bit of a birds nest under the seat, but definitely started out as a Baja Design kit. Has a rectifier (i believe) and a "holding shelf" for a ni-cad battery bolted in the air box.

Does anyone have a diagram of wiring for a 1998 WR400 Baja Design kit? I'm trying to make heads or tails of the various loose ends....

ANY HELP would be MUCH appreciated!

Chuck,
PM me. I bought a 2001 WR426 last year that came with an unopened Baja Designs kit. I spent a few days putting it together and not too difficult, but I didn't have to deal with a rats nest! If you PM me your email, I'll scan the original BD instructions and send em off to ya! I'm sure it will be a damn sight better than what you have now! I doubt much changed from 1998 to 2001 and the kit was purchased new in 2002 (yes, I have the receipts from 2002!). I'd put it on here but ADV won't allow posting of pics anymore without an outside photo acccount.

Thanks for the offer Marco, a PM has been sent. For reference purposes I have uploaded these pics on photobucket:

Ok....I believe these two wires, (1) brown and (1) green are from the original Baja kit. I think they are for signals which aren't at the moment on the bike. However, I'm not seeing any potential "open" grounds for them.

Ok, this next photo is a bit of a mess. The red wire running across my index finger comes directly from what I believe is a rectifier, then marries with the black (in-line) fuse which runs from what I believe is the original BD harness and then has the wire (open end/no connection..it is black but believe it should be red) that runs directly over my wedding ring? Clear as mud, right? The black wire that comes in to view directly at the tip of my middle finger also originates from the rectifier. It splits a few times and appears to be a ground for a few things.

As I have been typing this, and running a couple times back to the bike, I think I may have a plan. Each of the brown and green wires to an individual rear signal, each grounded to an open slot in the "two place" ground connections for my rear brake light....

I think the red and black wires described in the second picture will be run to the nicad or nihm battery....i "thunk".

Sorry for the rambling!

Hey Chuck,
The rectifier takes the two wires coming from the alternator (AC wires, no positive or negative) and comes out with a red (Positive) and a black (negative).
Now the guy wired the positive through a fuse, which is ok, don't mind the black color here, just keep in mind that that is the positive.
If you're not familiar with a multi-meter, I would download the schematics for that particular BD kit, that way you can match the colors of the wires coming out of the handlebar switch.
Basically, you have to take the red and black wires coming out of the rectifier, connect them to the battery and then with another set of red and black run the lights. Meaning split them into:
a) one wire to go to the switch to run the headlight and tail light;
b) one wire to the front brake switch;
c) one wire to the rear brake switch.
If you are installing the turn signals one wire will go to the handlebar switch that runs the signals.

Now, the second connector that is on the brake switches will have to be wired to the brake light, so these will be two wires merging into one.
Same scenario for the headlight, there will be one wire going to the low beam AND tail light, and another going to the high-beam and merge into the same wire that goes into the tail light.

Sorry, but this is not easy to do "remotely" I wish you could come up to my shop and I guarantee you that we could solve this in 30 minutes.
I live right in the middle of the Mitt, north of Mount Pleasant, let me know if you are coming up for any reason, I'd like to help.

...probably not.

Ok...so what have folks "strapped" on to their early model WR400s? Mine is a 98....or has someone actually had any success locating a rebuild kit? So far, lots of searching for a kit of replacement seals/o-rings/gaskets with no results.

Thoughts?

Thanks!
