Regulator/Rectifier
 

Hi Everyone, just thought you'd like to know, checked connections to the above today on my '08 Ten and they are fine. There is no sign of corrosion or overheating.
Regards;)

Mine is at the Yamaha dealer waiting for a new one! :tazdevil:

<mutters under breath>

Had you taken any preventative measures? Is it now new regulator and wiring loom? Is yours an '08 model? Done many miles?
Sorry for all the questions but I'm trying to understand what factors might contribute to the failure and whether I've got it to look forward too.
Cheers:001:

2009, just under 4000, I had put rubber round it and cable tied. Funny thing was it was on the very first dry roads day I commuted on it.

Still at the dealers so what they are going to end up doing to it I don't yet...

Orangejohn, you should be fine. The problem seems to arise when the connector is not pushed fully home and making good connections. You are so right to check it and make sure that the cavity is clean and no water in there. Probably fill with vasaline or similar and make sure that it is fully home. I had the original problem and since a new loom was fitted I have had no more problems.
Not to self, check the connection this weekend!:hello:

I've done 30000km's so far and no problem whatsoever. Indeed make sure it's connected firm and sprayed it with protection spray.

Can you give me a name of the protection spray?

i use ACF50 although expensive it does a great job.....good for covering the engine as well to protect it

Anything that is oily and sticky, (lard, fat, grease, chain lube), but the key point is to make sure it's properly connected - 2 clicks when you push it together.

17,000 miles through everything and mine looks all clean and shiney (inside) but is covered with marine grade grease on the outside.

Guys, can someone please measure the voltage on the battery when reving the engine at 5000RPM? Mine gets to 12.98V when most bikes would give at least 13.5V when charging. Thank you!

14.16v @ 2000

Same voltage right up to 5000


When watchind the meter, the voltage does drop a little (~0.1v) when you rev it but steadies out again when you hold the throttle steady.

Does this help ?

14.34v and steady at tick-over, 2000rpm and above. As with GULG mine dips by a fraction under rev increase but soon settles again to the same.

I've got mine back from the Dealer with a new rectifier - should they have replaced the loom too?

I would not expect them to if the connector block and terminals were in good order, but without seeing them its difficult to say.

Good luck

Thanks guys!
