Speed Triple T509 Alternator

Hi all,

I've got an unwell alternator! I know the collection of parts on a motorbike are not really called that but as its all packaged as a single unit on the T509 I think its just about OK.

How do I know its the alternator? ride the bike with lights on and it drains the battery, then won't start. I've made sure the battery is OK by monitoring it from fully charged and it holds a consistent charge for days, I've performed a leak test and that was fine and finally I completed an output test. The battery sits at around 13v with the ignition off and dips very slightly with ignition on. Rev the bike to 5,000rpm and the battery has around 5-6 volts. Doh!
I removed the brush holder and brushes and they are plenty long enough (10mm) and clean and I have cleaned the slip's too.

So my question is, have i missed out something? or do I just try my luck and buy something old and dirty from eBay or is there a secret stash of these units (or components) that I haven't found?

 

Thanks for the replies fellas, useful information... But on the T509 the stator and reg/rec are all packages as a single unit. Triumph never made the components available separately hence me calling it an alternator.
If the reg/rec is gone you might as well replace the whole thing.
What I was really after is advice from someone with the same engine who's had a similar issue.
Anyway I found a tested replacement alternator on eBay for a bargain.
Thanks again.
Here's a picture to show how it's all packaged together.

 

My picture upload clearly failed. Google T509 alternator or T595.

 

Yes I realise it's all together in one unit did anyone bother to read this? I've mentioned it myself a few times... I've also mentioned I've got a new reg/rec and stator...aka an alternator unit coming. Thanks all for your opinion on egg sucking techniques. It's been a trip!
