My 96 xtz 660 yamaha tenere has electrical gremlins

#1 Unread post by corey77 »

Ill start from the top.Like every other morning I start my bike warm it up then ride to work a couple of k's away.
When I come home I park her in the shed and plug the battery saver charger
on and leave it at that>
Next morning I was running late for work so I rushed out put the key in the ignition all the dash lights came up like every other morning then hit the start switch, heard this little pop and everything went dead, being in a hurry I forgot to disconnect the saver charger thought 'there goes the main fuse" jumped on the pushie and went to work.
When I got home I checked the fuse and It was OK on sunday I stripped the bike down including the Tank to find any trouble wires then it got really weird
when I turn the ignition on only the neutral light comes on and thats it, when I hit the starter the light goes dead no horn no lights nothing then i found this mystery black wire that runs from the negative battery terminal when I disconnect it the neutral lidgh comes on and when it is connected the neutral light goes off the wire looks like it runs either to the radiator fan or somewhere up to the ignition.
Sorry I am so long winded but if I have to take it to the shop and I dont want to look like a wanker if it is something really simple
Bottom line is electrics is my weakest point and Im trying to learn them

Hm, it's difficult to make a recommendation without having a wiring digram handy. It seems to me like one or two things.

First, you may have blown a cell in the bettery (Rare but not unheard of.) You need to test the batteries voltage and make sure it is OK. The fact that your Neutral light only has enough power to fuction when other electrical appliances are diconnected leads me to believe that your battery may indeed be dead.

Another fault may be in the wiring in the starter circuit. If you have a premature ground (Perhaps the stater relay has failed) It would cause the pop you described and the situation would also be exacerbated by pressing the start button.

If you own a multimeter you can do some rudimentary tests - If not, I suggest letting an experienced technician handle the problem!

Thanks for your advice you were right the battery was only just on ten volts
and a new battery fixed the job, I always thought a battery would make a louder noise when it drops a cell but now I know, At least I got to check all my wiring and clean up any dodgy ones And I learnt a few things to

Hi,
Corey do you have a service manual for the XTZ? I am looking but having no luck.

Hey boxheadc
You must be having trouble finding a service manual as well. I can't find anyone who has brought out one either but I do have the owners manual that includes a wiring diagram I can send you a copy if you dont have one, It's come in handy a couple of times for me but it's no service manual
