Removing RLU on XJ1100j vs XS1100

[luckygpass]

Hi,

I was going to do the Mod to eleminate the RLU on my XJ and when pulling up the article and going over my electrical system I realized the article is XS1100 specific. The setup on my XJ RLU is different than what you show for the XS. Besides being located behind the battery, I have more wires in the connectors.

Has anyone performed this modification on their XJ1100j?
I searched forums with no luck using 'Removing XJ110j RLU'.

RLU?

DUH! Sorry, reserve lighting unit.

Just curious, why remove it?

Here is one reason; .

RLU = Reserve Lighting Unit; (Originally posted by TopCat)
"IT's only function is to send a reduced voltage to the high beam WHEN The low beam burns out, and to light the dashboard indicator light to let you know the bulb is burned out! So...you can do without it! "

...meaning; Since by nature it is an additional field for various electrical problems to manifest, it's benefit to the motorcycle's operator seems to be outweighed by it's detriment to the motorcycle's caretaker. Hence, surgery and bypass operation.

My question is if the same system and fix apply to the XJ as they do to the XS.

Hey Lucky,

Hopefully JERRY our XJ guru will chime in, but here goes!

I've reviewed the wiring diagram, along with Sid's RLU bypass and the description mentioned in the tech tips. Interestingly enough, the Blaine Hoopes info talks about the RLU on a Voyager which also had a computer monitor and such!

Anyways, the Blue/Black wire which is power should be jumped to the BLUE/WHITE wire which goes to the headlight hi/low switch!

There is a yellow wire that goes to the hi beam indicator, and you should jumper it with the yellow/green wire at the RLU plug.

The hi beam indicator has another wire, green that you'll need to find at the gauge cluster, where the wires come from the bulbs in the gauges, and cut it, and jump it to ground!

The other wires at the RLU are extra sensor wires, and the ones to the headlight that would provide lower power to the highbeam filament IF the low beam was burned out, but they shouldn't be needed.

But I am not an Electrical GURU, so hopefully either Jerry, or Randy, Geezer, or someone else who can read the wiring diagram can confirm or adjust/correct what I've said!
T>C.

Thanks TopCat,

Here is a confusing question;
Do I Jump the blue/black wire to the blue/white wire at the connector - headlight side? Or blue/black RLU side to the blue/white headlight side? Or will I be removing the RLU? I did not think so because you say to jump the yellow wire - headlight side of connector to yellow/green wire at the RLU plug.
Or do you mean jumper it at the RLU plug - Headlight side, removing RLU and it's plug - RLU side altogether?

Need Help with RLU removal/bypass on XJ1100j

I am trying to get a history of anyone doing this to an XJ1100j.

TopCat reviewed and gave a solution but would like reconfirming or additional input from you XJ1100j Guru's, etc. out there.

meanwhil, Thanks to All, once again.

Hey Gary,

Most of the jumping splices are intended at the RLU plug. I can't tell whether Blaine Hoopes mentioned removing the unit or just leaving it plugged in except for the mentioned wire jumps? The only other place to jump is the green wire at the gauges for the hi beam indicator light, needing to cut it and jump it to a local ground.

Hopefully Jerry or someone will chime in soon. T.C.

I think he jumppered the wires rather than cutting them like my tech tip sez. I really didn't mind removing the unit forever, so cutting was OK for me.

Hey Skids,

On the XS, I agree that it's okay to just remove the unit, but with the XJ and it's fancy computer monitor and such, was wondering if it might help to not give any extra problems with the sensors to leave the rest of the wires connected to it/plugged in aside from the aforementioned wires to cut/splice/jump vs. completely removing the unit.

Oh. I got lazy and didn't read the whole thread. By bad! I gotta start doing that.

[luckygpass]

So let me get this clear.

RLU modification;
Leave the unit plugged in. Cut & splice to jumper the wires as determined to bypass the main RLU function.
Make jumpers on bike side of RLU component's connector and jumper green wire coming from dimmer switch to headlight to ground at instrument cluster or in headlight bucket.

Has anyone done either version of this mod on an XJ with positive results. If so, which version?

Has anyone done it both ways, removing completely and jumping appropiate wires, or leaving in place, jumping appropiate wire?

I'm still not clear and would like to verify before I start hacking.
