Topic: Signal light, headlight, tail light all flash together - Wiring confusion

[albertaboy]

Hey All

Bike is a K5 750. Re-pop main harness from Parts n More, used one season, I had no issues then. I have just replaced my handle bar controls with Z1 Parts re pops. I have a new flasher from my local auto store.  I've kept my battery on the tender.

Here's the problem
Whether I switch to my left, or right signal light, my headlight, and tail light flash with it.  Then, when turn my head light switch on, all four signal lights come on a stay on but don't flash. With that switch turned to on,  the headlight and tail light, light like they should. High beam also works like it should.

I read somebody had trouble with a Yamiya repop handlebar control but I can't find that post anymore. I suspect Z1parts and yamiya sell the same control(?)  If I recall correctly, the control was miss wired (?), or a short(?)

If this is a ground problem or a miss wiring problem, I don't know where to start. I've checked all the connections in the headlight bucket- the colors match all appear correct.  How does one verify the handle bar control is wired correctly?  Any suggestions?

In the pursuit of solving my own problems but not understanding electrical concepts or how to test for this problem,  I thought I could test this by unplugging my new right hand control and plug my old one in.  I got the same results.  Here's something I find odd- with the kill switch turned off, the bike will start (runs rough) with both the new and old control. Both kill the running engine.  Any ideas??  Thanks.

Well, how did you screw that up!?!?! I'm rescinding my BOTM nomination.


Actually, that harness has a known issue. I think Tews had same problem and MatMooradian (iirc) pointed him to a thread for resolution. It's not your fault afterall. (Electrical pin intended  )

Do you have a wiring diagram? Do you have a test light or multi-meter? Your probably gonna need both to effectively troubleshoot.

Did you switch both controls? I'm suspicous of the left one.

From Tews: I have ep36 flasher. Alberta needs to get the spare green ground wire and hook it up. That will fix it.


Hope that is helpful

Hey, 
I ran out an grabbed the last EP36 at my local auto store and hooked all three wires, Grey black and that spare green to it.  Nothing. Actually functioning less now, in that before the signals would flash with the headlight switch turned off. Now with the ep36, no flashing.  What can this point to now? Bad flasher?

hi/lo beam and turn signals are both in left control right?  It sounds like a cross feed there.

This might help...

I'll have a look at that, thanks Don.

Cool, Thanks for this too. I didn't realize that harness was an Emgo. Big question for me is why mine stopped working- but that's why I find wiring so mysterious. lol. I also have the wiring diagram (has been a big help so far), test light and a multimeter- still learning to how make it work for me and understand the results when it does.

Much appreciated Gentlemen. I'll go from here. Thanks.

Now you have no signals with the ep36? Is it hooked up correctly? Funny cause today my bike loss complete power. I have the yamiya controls. Before with the issue I hooked up the dyna ignition incorrectly. I fixed that. I do not recall at the moment but do you have to ground the turn signals in the headlight bucket?

[BPellerine]

check your plugs at the left hand control there is 2 that are similar and will plug in one will be normal and one will give you the symtoms you describe try reversing them did the same thing myself.hope it works.bill

That's correct-no blinking now. What is correct? Grey black green go on in a specific order? I did try three different combo thinking there may be an order but no luck.  I'll know more tomorrow hopefully I can find a couple hours... I'm back on night shifts at work and no longer of the land of the living.

Cool I'll check that too. Thanks.

Here is a pic of my set up.... zoom in. You can seen where each wire should go.

[calj737]

Not to be a Tattle-tale, Tews, but isn't this the bike that just caught fire due to electrical?
 











Only kidding- hoping AB reads this while kind of sleepy. Ought to snap him awake pretty quick.

[Tews19]

Lol! but the flasher is set up correct. Alberta hook that bad boy up this way. If the bike starts on fire, well, um, sorry.........

Haha... No fires... um  yet. No liability upon you Tews Ok. Here's what I've done. I went back to my other two prong flasher and got the signals flashing again. Then, I read in BrandEn's link above where HondaMan recommended connecting the brown headlight wire with a spare black that was just dangling loose in the h/d bucket.  Bam!! Everything works except for one thing.... I cant turn the headlight off. It's on full time now. I think I've invented something like a modern safety feature... cough cough... actually Im worried something is going to heat up and melt later on. lol. 

Tews, I went back to the ep36 so I could plug that spare ground(?) in. Except the h/l on off switch, everything is working.

This is a step in the right direction at least.

I am left with a brown with blue strip wire ( in the bucket that) with no home. It appears to come from the left control harness but I do not see it's match in the wiring diagram. The closest to brown with blue looks like the oil pressure light except, that light works as it should.  Anyways I taped it up for now. 

Anyways... I'm sleep deprived and shouldn't be working on the bike.

Thanks for everybody's help, suggestions, sense of humor so far.... I appreciate it.

Don,
I didn't get that far with trying the jump from the brown head light to the black first. That solved most problems except the headlight switch, which is right hand on my K5.  I'm still not finished with this though. Thanks for you help.

I had a look at that. I did in in fact have a, left hand control, brown with blue strip wire plugged into the solid brown. Now I've connected the solid brown to a spare solid black as I described a post or two back and I'll have a closer look when I get more sleep on board.   Cheers.
