Charge the battery or if possible jump start the bike off a car. With the engine running put a meter across the battery terminals, set to 20V DC. You should see around 12.5V with the engine running, rising to around 14.5 V at 5000 RPM.

Green with the SOLID coupling..
Quote:
We've come to refer to the different types of alternator and drive by the parts label on the alternator itself. The 'early' type with the solid drive has a Green label while the later rubber coupling drive type has a Black label.
Note that you can't fit a Green label alternator into a rubber coupling or a Black label alternator into a solid coupling - while the physical dimensions of the unit are the same the shafts are different
i did start to consider saving the pics just for the SHED, so let me have a hunt through my Gdrive and if i can find any i'll try and insert into shed as per fastys pics..

hope some of that helps..
