Problem is back again and bike returned to local dealer. He says the regulator and generator are working fine but once he moves or shakes the loom, it breaks the connection and charging stops.

I did inform him of a few looms being replaced by Yamaha so he contacted one of Yamaha UK's technicians. They denied their being any recalls or widespread replacements of looms on these bikes. My bike is 3 years old so out of warranty.

I'm currently searching threads on here to get an idea of how many looms have been replaced by Yamaha on these bikes.

Just as well the bike is in the garage as the weather is absolute crap here ! :)

hi if you want, get a fz or fazer600 regulator [ebays a great source] and give me a shout i'll fit it as i live up the road from you in killean. that should end your charging woes

Hi Bernard,

Thanks very much for the offer. I really do appreciate it. Bike is currently with R P M down the road from me and I have passed onto them details of your fix and others experiences with getting looms replaced. Let's see what they can do for me.

After a bit of searching on the site here I've noted that about 15 XT660Z owners have had looms replaced.

Glad to hear you're getting it sorted...

It's not so much the loom that is the problem, just the connector that goes onto the reg/rec - the problem is that connector is part of the whole loom, rather than on a sub section (that could be disconnected independently if you see what I mean), therefore it is much more of a job for the dealer to do, as they have to strip half the bike down to get the old loom off, just to replace one connector. Is it any wonder Yamaha are reticent to do this as a recall?!

As Bernard says, the 'sensible' modification would be to cut the original connector off, and either replace the stock reg/rec (and connector) with another type and joint it with your own connector block or bullets; or to solder the wires directly to the OEM reg/rec and put a decent connector between it and the rest of the loom.

Thanks Jenny.

Looks like we're gonna go with the Fazer regulator fix.

Will report back once I'm back on the road.

Thanks for help folks.

Got the Fazer regulator fitted and now everything seems perfect.

Thanks again people for the help.
