So I put in the new EL 13 electronic flasher, it works well and actually got my rears to blink, however I have discovered a short or loose connection somewhere. If I jostle the wiring right by the switch I can get them to work, but it wont stay on.
Anyone who was on the old board knows I have had problems with the turn signals for like 2 years now. I just want to rewire the whole turn signal circuit.
I need your guys help to do this. There are several things I don't know where and what I should connect.
First what guage wire (16?) should I use? Where do I connect them to the switch (I dont connect all 4 to the switch, so how do i do this)? Where to the indicator light? I than run wire to both front turn signals right?
When do I run them to the flasher...and when do I run the to the battery or wherever they get the power from?
I am definitely not too familar with how things are wired on the XS, as you can tell.

No one can give me some insight on how they wired the turn signals. I am looking for a simple way to do so just so that they all work and hopefully will still be able to use the indicator light in the pilot box.

Hi, Jongordo8, I'll take a stab at this.
I rewired everything, so I can only offer concepts since the notion of wire colors is out the window for me. I used 14 guage wire everywhere, but don't think that's critical, 16 or 12 would work just as well as others.
What you should have is battery voltage probably split from a fuse block, headed into the flasher module. From there you come off the other terminal on the flasher module and head to the handlebar switch(L/R activator). This is where you'll have to consult a shop manual to determine what color handlebar wires do what.
From the handlebar switch, you'll split into a pair of "hot" leads to each side(2xLeft/2xRight). I have a 3 terminal EL-13 and run the third terminal to the indicator box so it flashes in time with the signals.
The signals themselves pickup ground through their mounting lugs.
Hope that helps, I know it's not very precise, but like I said, I ditched the factory harness right away. About half of it is unnecessary junk(IMHO).
Good luck, Pol

so it is pretty simple...when I started thinking about it I kind of got scared off cause I thought of all the places it could be run. Now do you still have the pilot box indicator working or no?

Yes, you could either split out of one of the leads that power the front signals such that either one blinking would also blink the indicator box, or you could do what I did(cleaner) and assuming you have a 3 terminal EL-13, run a wire from that third terminal directly to the indicator box.
Either should achieve the same result, the indicator box blinking in time with the turn signals.
Best, Pol

ok I have been exploring my options on what I want to do as far as wiring is concerned...after looking at this diagram: www.650motorcycles.com/ReadyKilo.htmlI think I want to just ditch the stock harness and rewire it following the diagram, however having an 81 I have electronic ignition (stock). What differences need to be made so that it will work? Also am I understanding this correctly that the only fuse with this setup is a simple 20 amp fuse running right off the positive from the battery? Will be fine to do, as the current stock setup has several fuses including a seperate fuse for the turn signals and lighting? thanks in advance.

If everything works until you move the wires to the switch, you have found an open (not a short). I bet if you just took the switch apart and cleaned the contacts with emory paper (wet/dry sandpaper) dipped in denatured alcohol you'ld possibly be ok. If there is really an open in the wiring it would probably be at a connector. When you move the wires do the lights stop working on either side (right side and left) or does it only stop one side. If both stop, then the problem is on the wire coming from the flasher (in your picture the short red wire). If the right side always works but the left cuts out then the problem is in the Brown wire of your picture. I really believe that you will find the switch is at fault, and moving the wires is only moving the switch contacts they are soldiered to.
