Greetings from Portugal

Bought a 2010 XT660Z alegedly with 14 k kmtrs on it 6 months ago and love it.

When I bought it there was evidence it had been previously been kitted out to cross most deserts in the northern hemisphere; panniers, top box, GPS bracket etc. and lots of black spagetti leading to unknown black boxes cable tied behind the headlight kit.

First atempt to drive it home 25mtrs from the dealer it died, all lights up like a Christmas tree then just packed up. Dealer replaced battery and regulator and it ran ok for a couple of k then started flashing error code 46 before refusing to start. All points to regulator and battery again but seems a bit weird given both bits are brand new.

Any logical input appreciated

It is not the regulator/rectifier unit that fails on the Tenere; it is the connector on the loom that causes the well documented problem of no charge, flat battery and dead bike.

Have a look in the connector on the loom and see if all the pins are intact and not corroded or melted. It is the earth pin in the corner of the block that is the one that normally melts and causes the problem.

Yamaha replaced the whole loom when rectifying (no pun intended) this issue, but for a bike out of warranty it is much more cost effective to replace the reg/rec unit with a secondhand one that has tails, rather than just a connector. This can then be spliced into the existing loom and the offending connector can be ditched.

Big thanks Pleiades. **** on with that diagnosis. Took the connector off and it looked shot to **** and full of gunk.

Cleaned it out as best I could and scraped up each of the individual small plug sockets one by one and managed to get it charging the battery again.

Obviously this isn't a permanent fix but a rubber boot from LR Industries sealed in place with a cable tie might keep it out of trouble for a while until I can come up with a "permanent" solution? Any point greasing up the connections, I have no idea how to do this or what grease to use so a pointer in terms of links would be good.

Cheers.

This is the stuff I use, it's generally rated as the mutts nuts when it comes to contact protection. However, any dielectric grease packed into the terminal block will do the job.

Just an addendum to the Regulator issue; went to see local Yamaha delaer in Portim�o yesterday and got him to run FI diag' doodah and check connections on regulator. His view is that it won't be long before female connector from loom is burned out so he rang Yam' Portugal and Italy and asked for a solution.

Upshot is they recommend replacement of the whole loom +/- 500 euros, yeah right, then on the QT they told him best solution is to carefully remove all wires from connector block and solder each one directly on to the 8 regulator pins, protecting each connection with heat shrink cable sheath. This would supposedly avoid any future corrosion issues, get rid of a crap connector, be totally waterproofed and could be undone in the unlikely event of regulator failure.

I'd be interested in views/input on this before I let Dr Frankenstein run amok with the soldering iron.
