Well spotted - didn't look close enough!

hi damomac, the regulator failure's a bit of a bummer, but not a hard one to sort out.

about 20,000 miles ago i replaced mine with a more suitable unit off a yamaha fazer 600, secondhand on ebay i gave �14 all in.

it has 5 wires; black, red & 3 whites. cut off the inferior connector and connect with corresponding colours, the whites [generator phases] are non specific to the regulator [any order]. now my connector probably is the weak link, perhaps in the future i will hard wire to the loom, soldering & heat shrinking to create a perfect join

because the 'new' reg has about 8'' of loom it's easy to point the wires down to stop any water ingress, secure the loom out of harms way. the reg needs a slight adjustment to align the holes, better to ream out the mounting plate and jobs done. now start the bike check the battery voltage should be above 13v with a voltmeter

Thanks for that Stoic Bloke and everyone else.

Spoke with mechanic and he confirmed it was regulator so he has one on order. I should have the bike back sometime next week and am really missing it.

Got the bike back and running great now with new regulator and DNA filters (thanks CaptMoto & Kev).

I started of using a balloon which soon perished so I have ended up using a part of a cycle inner tube which is still in one piece.

My bike is from 2009 and had the same at around 60.000km. Loom was replaced under warranty. Now that I am out of warranty I greased the connection to prevent corrosion.

My bike has been going great since the new regulator was fitted but I had a bit of a fustrating moment yesterday 1.5 hrs into a 4 hr journey. All was fine but suddenly the engine management light came on. Weather was nice and warm (seldom happens in Ireland :) ) so 1st thing to do was to get off the motorway.

Once I shut off the engine and read the code's, it stated 46 which the service manual refers to as

"Power Supply to the fuel injection system relay is not normal"

I shut off the ignition and put it back on, the light disappeared. As I didn't fancy getting stranded on a bank holiday weekend, I decided to return to base. All was fine on the way home, no more engine management lights but of course now the big question is, will it happen again.

The battery is the original (2008) and starts the bike every time I've tried to do so.

Any thoughts or experiences ?

hi for me, first check the battery, good connection? now check the voltage with the motor running, should be above 13v. was the connector or loom replaced? sounds like the terminal may have failed again

Negative terminal was ever so slightly loose although just noticed this once I got home, after the light staying off.

The original loom is still on this bike but the regulator was changed 2 months ago.

Must replace my multimeter and will check voltage once I get back home.

Thanks SB!

I just had this exact same problem 2 weeks ago. At 8000 Km (!) the engine orange light came on. After turning the engine off it wouldn't start again. It would only give a strange sound from the starter.
Went to the dealer and they replaced the entire wiring system and the rectifier (under warranty).
According to them, this happened because I have a Touratech Rectifier cover. I almost sent the guy to a place I know... :icon_rolleyes:
