To the OP i'm not trying hijacking the thread, although it sure looks like!
So today i got a few more piece on my puzzled head. A friend borrowed me his '06 990S voltage regulator so i could test on my bike.
Usually these test are followed by a big grin, cause we're almost sure what is the cause. Well...not this time! The voltage was slightly different
engine off: 12,8v
engine idling: 13,9v
pushing the revs: 13v ~ 13,2v
Put the regulator back on friends bike, started the engine, same results. WTFFFF????
Just to complicate a bit more, there was a brand new Dakar at the shop, tested the voltage and it showed:
engine off: 12,9v
at revs 14v
Shouldn't it be at 14,5 or something?
