Head lights problem

[nitronori]

Hi there,
suddenly I faced a black out on my XT1200Z:

a) tail light is working
b) turn key: small lights are not burning
c) turn on engine: head lights not burning
d) high beams: not burning (but blue lamp burns on dash)
e) parking lights: rear is burning front not burning

bulbs are ok
additional lights (not OEM) are working in conditions b-c-e if switched on

anyone can help?

Assuming that you checked the fuse already. . .


Seeing that you have a 2012 in Italy, I am not sure if you are aware that there was a recall to replace the set of wires (harness) which go to the headlights. What you are describing sounds like that harness may have melted.


You might start by pulling the rubber caps off of the backs of the headlights to see if the wires are good and the connectors are not brown. If OK, the other end of that harness is beneath the upper right side panel, next to the fuses. The next step would be with an electric meter, to check each wire for integrity and for short circuits to the frame.

yeah fuse is ok, already replaced with fan one with no result
harness are ok, but note that also parking lights are not burning, harness issue is only for headlight isn't it?
i also removed both right side fairings and nothing looks burned, do you have a picture where is visible component positioning (relay, connectors....)

thanks for help

If your fuse is ok, and the harness appears ok, it very well might be your negative output from the ecu not working. That said, if you turn on the bike (ignition only), then start the bike, you should hear a low beam relay click (see the blog post). This would verify that your ECU output is ok.

But, you say that none of your lights work. The harness shares the negative wire for all lights (park, main, shutter etc). There is no high beam light, as the bulb is H7 single filament. The shutter simply blocks half the light on low, and opens for high beam. If your negative wire is compromised, you don't have a complete circuit.

If I was a betting man, I would say it's your harness. If you follow the lighting harness back, it should be plugged into the main harness just above the relays.
it will either be bad around the headlight connections, or somewhere near the lighting harnesss/main harness connection.

let us know how it goes.

pull the connectors off the head lamp bulbs and see if the other lamps start working, if so you are shorting somewhere on the head light harness

hope to have some spare time in the weekend to check

thanks to everyone especially to Greg really complete explanation

No worries,
lots of use less info on my blog ::025::

Thanks everyone for kind help
Harness was Ok from outside but ground faston inside connector was loosen with sign of sparks
Tightened with small screwdriver and now working
Strange to have this kind of defect after 45'000 km but glad to have solved with 0 cost

Thanks for posting how you fixed this I had the same thing this morning so headed straight to the connector for the headlamp loom & found it to be as you described working fine now ::012::

I know this is an old post, but my headlights stopped working after 27k miles. I found both bulbs blown but they didn't light even after I replaced them. I basically unplugged the wiring harness an plugged it back in and the head lights worked! Unfortunately, after I buttoned the bike back up, they no longer work. Does the above mean you guys bent the pins within the connector to make contact? I think it does because I see nothing else I could do with a screw driver as mentioned.

We've had a couple of owners find the pins loosen the crimp on a wire. You may find a brown tinge to the white plastic if you look close and it may be invisible till you play with the wire a little and the circuit breaks (open). The other thing a few folks have found is that simply opening and re-closing connectors restores function as yours seemed to. This could be from a bit of surface oxidation (corrosion) developing on the pins.


Rock some of the wires at each connector to see if the crimp is an issue.


If not, pull the connector and re-seat it a few times. When you put it back together the last time, put a touch of dielectric grease on the pins.

What year is your Tenere ? Are you aware there is a recall for the 2012-2013 headlight wiring ?

It is a 2013. The dealer said he installed the new wiring harness prior to me picking up the bike but I am not certain how to verify that.

Probably the most accurate way is to just take your VIN to any Yamaha dealer and they can run it and see. Any dealer should be happy to do this.

Regarding the headlight harness, I got my bike used from a Yamaha main dealer, who confirmed the harness had been updated as he had done it himself (was talking to the mechanic in the workshop). He told me that they also stamped the frame numbers with I think an *, near the headstock as confirmation of being done. True or not, no idea! (mine does have an *)

 

[CowboyJim]

I called the dealer today and they confirmed that the harness replacement was recorded in their database just before I purchased the bike. Time to pull the plastic again and work my way through all the pins in the harness.

To see if the new harness is there, just simply look at the wires. The wires on the updated harness are much heavier wire. Heavier wire is a relative term, and AWG rating may not be familier to most, but the original was like a 24awg wire, where the updated is like a 18awg. If not familier with wire, just look at it. Does it have "normal or larger" than wiring you see all over the motorcycle? If yes, than feel confident the updated harness has been installed. Look at the wiring and see tiny wires 1/2 the normal size, no the harness has not been replaced. In any case I doubt many times while replacing bulbs the pins need to be tweeked in any way.

I thought I would follow up on this post in hopes that others don't make the same mistake that I did. It is easy to think that you have an ECU problem after reading some of these posts. In fact, I thought I had a bad ECU because I couldn't find any problems! It turned out that I was the problem. After replacing the headlight bulbs, everything worked fine. When I turned the ignition switch back on, the lights didn't work. Why? Because the good Yamaha engineers designed them that way. Once the motor is running, the lights will come on, no problem. So my issue was user error because I didn't realize that the lights won't come on just because the ignition switch is on. The motor must be running too.

Åh no....didn't think about that somebody did not know this..
Glad you found out your self ::008::
