I've had similar problems on my '09 848 (as it seems many people here had)

After replacing two V/R's eventually it turned out my alternator was defective. It was generating way too much output (approximately 200% at 4000rpm) and fried my V/R's.

Replaced the alternator and installed a mosfet V/R and now everything is steady again:dance:

Long story short... Just measure the outputs before you blindly start spending your money replacing stuff. Measuring will take like 5 minutes and the removal of the left side fairing.
