This mod went poorly for me. I discovered that my headlight wasn't working as I headed home at dusk. I pulled into Meijer and grabbed some wire strippers and tape to reconnect everything to get me home safely. Now I'm in the position of what next. Do I reattempt by splicing or do I go for the blue wire solution? I'm leaning towards splicing because it saves another snip.

This is my connector before mod. I cut y/r and b/r, connected them off the plug and capped the ends. I'm willing and able to go in any direction but am not confident in the best path forward.

Also, my 10 pin connector is super easy to remove. Just a little thumb pressure on the tab and it pulls right out. I saw that some were struggling and thought I'd share my technique.

What do you mean by poorly?

Just do the headlight relay bypass mod. It was already mentioned in this thread 1-2 pages in...

I'm an amateur and didn't verify headlight function before going out. Now my game plan has changed and I'm looking for guidance.

Is that better than splicing like plee911 did?

If you splice like plee911, you're making the headlight relay work again (you snipped a necessary wire by following the original post's instructions).

Most of the people in this thread would advise you to do the blue wire mod to bypass that relay, but it isn't needed. It would be one way to bring your headlight back to life, but it would change its behavior to be on all the time instead of coming on when you start the engine.

"Better" is sort of arbitrary in this case. Do what you're most comfortable with. You can accomplish the blue wire mod without cutting anything, so it is a reversible process if you choose to do it that way.

 

[Thorn]

Just checked the schematic, and Jb87 is absolutely right. On a stock bike, splicing black and yellow/red together without reconnecting to pin 13 of the junction box robs the headlight relay of it's path to neutral for the primary/coil. Doing the blue wire mod (bypassing the headlight relay, thus removing pin 13 from the headlight circuitry) would be an alternative to reconnecting to pin 13.

So either do the blue wire mod or connect your black and yellow/red splice to pin 13.

These are your two current options, having missed the boat to 'just jumper the two wires together' without cutting anything in half, like michiganteddybear says he did. Just like splicing, that provides the relay with it's needed path to ground via pin 13.

I appreciate this. My comfort level with electrical work is low. The headlight failure seemed to be hit and miss and I suppose I was hoping for a miss. I have now successfully completed both the two wire mod and the headlight bypass. All is well. I'm going to back to wrenching. It's safer there.

Getting as much as possible away from the Junction Box is best, in my view. The start relay and headlight relay are two known culprits.

1) At the Junction Box, find the 10-pin connector (smaller of the two)

2) Locate the yellow/red stripe and black/red stripe wires (Kawi also used all black instead of black/red)

3) Remove the two wires from the 10-pin plug

4) Splice the two wires together securely and insulate properly.........That's it!! OK that's not confusing,remove these two wires from 10 plug JB (Took me a few minutes...Junction Box!!) Splice these two "loose" wires TOGETHER...DONE!!So you do NOT cut wires then splice the two cut wires on the "plug" side together,coming out of the JB(??)....or do you splice the "longer" loose cut wires heading "out back" together??I know these questions are Moronic,guess it would make sense to splice the two coming out the JB.BUT...LOL if you remove the wires from the JB,then splice...its like connecting two "loose" wires,same as cutting them and NOT going through the JB.

 

[vulkan]

Don't get me wrong...I'm all for "the easy hot start"!!

 

[Spockster]

No. The two cut wires on the JB plug don't get spliced together. Just insulate the ends. You are splicing the two wires in the harness together.

OK thanks....hope my headlight functions!!

 

[glenn]

I have the same problem after I did the the wire snip on r&r
did you find out how to fix it?

Be sure you're working on the 10-pin connector.

Thorn suggested the Blue Wire Mod in the other thread... Did that work for you?

 

[Ron Ryman]

Just for clarification I did the 2 wire mod as directed by spockster . have any affects on the headlight operation? I did this on my 2001 750 no black wire cut. Im working on another issue and bike is not running yet. please advise.

Done correctly, it should not affect the headlight operation.

Edit: Maybe it does affect the headlight relay, see the next few posts. If it needs the Blue Wire mod, that's what I would do. It's just trouble lurking if you leave the three JB relays in operation.

Thanks I thought So
Very excellent explanation! Word cannot express my gratitude Dr Spockster and staff

Change "done correctly" to "splicing the black into the yellow/red, but leave the yellow/red connected to the JB" and I'll agree. Every schematic I've seen indicates that the removal of the yellow/red wire from the JB removes the ground path for the primary coil of the headlight relay, requiring the blue-wire mod to be done to get your headlight back.

 

[Ron Ryman]

I did this yellow /black. red /black cut from J.B.and joined togather. If I do not want to do the blue wire mod ? Do I want to connect these 2 wires back to the cut yellow /black ?? I left enough of both attached to the plug to join them???
