Charging system testing- weak starter? just clicking? Is it the battery?

Great post, thx Thumper

I`m now sitting with a suspected charging issue...
Been noticing that for the last couple of weeks the starter is weak in the mornings and the headlights are "flickering" when the bike is running.. Yesterday afternoon; ignition light very weak, no power to turn over the motor at all. Luckily got her kick started and manage to get home.

This morning I slapped the multi meter on, voltage fluctuating between 13,8 and 14.2 volts, almost like a sine wave. Suspecting its the voltage regulator....
