xt 660 z charging problem - .: XT660.com

Maybe this problem�s been on this fora before, in wich case I apologize for being lazy not searching enough.
I have a tenere z -09. Love the bike but been having some problems lately. The loading stops working, the yellow light starts blinking and when I stop the battery is drained. Yamaha havn�t yet found whats wrong!!??
The first time it happened I found that the kontakt from the regulator was a bit black inside. I cleaned it and loaded the battery and it worked for a cuple of weeks. Then it happened again. Left the bike with Yamaha.(don�t want to screw up the guaranti ) They changed the cables from the reg. including the kontakt. It�s all put together as one pice and you�re not supposed to take it apart.
After a couple of weeks it happened again. This time I was stranded on a highway Yamaha picked me up in yust a couple of hours (good so far) Now they are saying they can�t seem to find the problem, they have run computeranalys, but that they will try change ing the wiring in the generator. I was planing going north by the high mountains in Sweden and Norway next week. Don�know if I dare now. Not a soul for quite long stretches sometimes and for certain don�t want to be stranded there. Anyone has any idea? Sorry about the English.

Rednax, search on 'Regulator' you will find lots of information about what happens and how to resolve it. You are correct, the terminals in between the reg / rectifier and loom are not making a good connection, hence not charging. Show this information to your dealer or better still get them to have a look at this web site.

Hope this helps.

thankyou ! Getting to understand the problem now. Don�t know why the guys at Yamaha doesn�t seem to.

had my bike in Yamaha workshop for a week and a half now. A new bike with a fault covered by the guaranti !! Will probably get it back tomorrow. All plans for my vacation totally f-d up. They have changed the collector in the generator now...I now (after studying the different threads on this site) also realise what the yerking when I�m trying to go slow and even in the city is about. Thought it might be a fuel inj. adjustment thing, but it�s probably the rubber cushings back there...after 6000 km !! So what�s next ? I�m NOT feeling confident about taking this bike out on any real adventure. Maybe the good feeling will return when I�m on the bike again, ( I AM suffering from a case of bad bike abstinens and the time is 4:30 in the morning and I should really

) but I seriously doubt it . Don`t know what the knext problem will be.....It�s a real pity, such a sweet bike to ride. Also after this, I can�t say I love the Yamaha people here

Even though I�ve had quite a few deals. bought two bikes (one for my daughter) and sold them one at a really good price, not to mention everything else I�ve bought, they made me feel really bad uring this process. Well, it might be I�ll visit the BMW dealer tomorrow or KTM or...so f-ck them!

If your bike has been fixed correctly you should not have any further problems with the regulator.

These XT660's are very reliable, with us knowing 99% of the problems with them. Hopefully your faith will be restored once you get back on your bike, time will tell.

finally got my bike back today and of course feeling a bit better after a ride. Still pissed though for loosing a great bit of my vacation and not getting the time to do the trip I was planning. The fix that was made...well, the collector is changed and the contact from the reg. is now smeared in grease and wrapped in electric tape..don�t know if you can call the last a good fix

, but I guess they havn�t got anything better to offer allthough they really should imo. It can�t be that difficult or costly I think and it seems a lot of bikes have had the same problem..
Anyway, reading your tecnical advises on this site with great interest and looking with more optimism on the bike (for now) in hope that you are right. Thanks for your time.

rednax - sorry to hear that this issue has messed up your trip plans.

This connector is known to be troublesome and from new I stripped mine to make sure it was well connected and coated in top quality ACF50 and have not had a single issue in 2.5k miles. The cush drives seem to be made of soft cheese and fail early, so there's a known fix to wedge some old inner tube material in with each drive rubber. You should be able to get new cush drives under warranty, so keep those fresh as a spare set and make the repair.

Keep an eye on the connector as you travel if you're worried about it - it's easy to get to - and treat yourself to some sort of trip.

Good luck and keep the faith - not everything's perfect, but the Tenere's pretty close..

Glad you got it sorted mate.

Glad you got yours fixed.

I had the same problem just before my warranty ran out !

Yamaha replaced the loom and reg/rectifier and now all is well again.

I had taken all precautions listed silicone grease and inner tube but it just wasn't enough to prevent the fault.

I am loving my bike again now and I think you will too with every KM you ride with no problems.

have fun Ride On

took my bike for a very nice ride today. Visited some friends and then headed homewards pleased and happy..Then IT HAPPENED AGAIN!!!!! The yellow light came on, stopped the bike and yes the battery was empty. Yamaha has had TWO TIMES WITH SAME F-NG PROBLEM and now I�ve towed it to them for the third time !!! Yes I used a trailer, but in my fantasy the bloody bike was screathing all over the asphalt behind me! It just cnnot be possible that yamaha workshop has made a thorough, careful, solid examination of my bike looking for the problem, can it? And yes,the bike has been wet in heavy rain for a day. My latest exbike ( a-99 900 x diversion) was really wet for weeks sometimes but never ever complained about it and this one is supposed to be the adventurebike...? Strangely enough, because of the way it handles ****roads and heavy citytraffic, I still love the bike....
