Graham, do you eat Haynes manauls for breakfast? notworthy

I had a quick look on the interweb and it wasn't clear, thank G, seems a strange part to repair , I assume its being replaced and MMC were trying to get to the cause of the problem.

Haynes, not often, I'd be getting things wrong more often than I do now...
Wheatabix? I think I'd rather eat the packet (or am I confusing this with Corn Flakes grin2 ).

John, stators do fail occasionally. If we were looking at a car engine, we'd just swap out the alternator. But on this engine, it's a bike engine, the 'alternator' is within the main engine cases (not crankcase, but under an outer cover normally).
Most bike engines that I've worked on have the rotor on a spur directly connected to the end of the crankshaft, so the rotor turns at engine speed. Sorry, not a great explanation - it's easier to draw on a piece of paper...

While not common, stators can fail - a winding in one of the coils may go open circuit or could go short circuit within a coil, thereby reducing the output from the alternator. If there is misalignment, the stator coils could be damaged by the rotor...

I guess what I'm trying to say is that the alternator (rotor and stator) are within the engine cases on most m/c engines, whereas on most car engines they are in a separate housing, belt driven from an accessory belt... Does that help? surrender smile

On the Three Wheeler I believe the alternator is behind the engine in the area of the Cush Drive Housing......so my dealer tells me.....he had a problem with his as well!

Ok, I've done a 'quick' search but just got photos of cogs, what is a cush drive? I am actually interested, not trying to find the one question Graham can't answer laugh2

No worries Mike!

J - might be, I've not had a chance to look at the engine yet... My comments were fairly general smile

A cush drive is v v commom on bikes - and the M3 has a massive one fitted behind the engine - what is does is to iron out the peaks and troughs of engine output/torque ...and makes for a smooth output of power...........Harleys had them fitted as standard ...the M3 may use a HD one..not sure!

Hope this helps...
