Did you get this sorted?

I've been having starting issues for the past few months now. I've checked charging voltage which is 12.6 at idle so there is a charging issue. Would you suggest I change both reg/rec and stator?

I was hoping to get away with only changing 1 but your experience suggests otherwise.

Tom spurs, will do but have heard very mixed reviews about them.

There's a test you can do to see what your stator is up to. Unplug the, um, plug, with three wires going into the regulator rectifier. I think it's the bottom one of the two on the right hand side when looking from the rear of the bike. Start the bike and measure the voltage on each of the three wires in the plug. The earth of the multimeter goes to the frame, the positive into the plug. I'm having a moment of utter brain fade, but I think we're measuring A/C, no? Also, I can't recall what the voltage should be. It's something like 10v on each of the three pins (one pin for each of the three phases on the stator). I can't locate where I read about the test at the moment, but have a quick Google and it'll turn up. It might have been on Triumph Rat.net. Someone please rescue my tiny brain and fill in the gaps... You can also test for resistance or inspect the stator manually and look for burnt areas.

EDIT:

Mattr6 yes I sorted it....new reg/rec from roadstercycle.com in the US. An upgraded MOSFET FH020AA one....bit of an arse waiting for it but it's a genuine MOSFET reg/rec, not a fake you can get off fleabay. They got a vid on you tube on how to tell. They sell different adapters for each type of plug/wiring harness type too.
Didn't get stator from WCW, went with an RMStator from motoelectrical.co.uk this time round but got it  via their Ebay listing as it was cheaper.
Both working fine, great voltage, not had an issue since. Would recommend both.

I filmed replacing both and have put on you tube....search for my channel called Gypseys Whippet

Quality filming and editing  :001: :008:

When I got the first stator from WCW they recommended changing reg/rec at same time to be on safe side.....wish I'd have listened!

Gypsey Whippet, great videos. Just trying to decide whether to attempt it myself or stick it in to local shop. Can't see them charging anymore then 1hr labour for fitting new alternator.

Really cant afford to change both reg rec and alternator at the moment so will need to do some checking/testing first.

Bringing this back to the top again  :431:

No real progress, but I've had a good look at the rectifier and it has the number fh012ab on it. Is this a mosfet one? If so, do these go wrong or can I assume that it's a stator and/or wiring issue.

Cheers

Yes, and yes.

On the latest Street Triple they use the FH020. In fact, if you look on Fowler's website, I think you'll find that they would supply you with an FH020 now even if you ordered the standard reg rec for your bike. They are available secondhand on eBay for about 70. They are used on other bikes too. I believe it has a built in heat protection circuit now so it can't be burnt out by a failing stator.

Did you remove the left hand engine cover and have a visual check of your stator yet?  Did you test yours with a multimeter?

Thanks for the reply. The only test I have done is to test the battery when idling, 12.5ish volts so I have a charging issue.

The bikes off the road now for winter so hopefully I will be able to pop the casing off and check for any scorching.
