Test for voltage. We Yanks understand it better.
At idle, with a fully charge battery, there should be at least 13.5 volts (DC) at
the battery terminals. That should go up to no more than 14.5 volts (DC) as you
bring up the revs. Seeing a very small drop when doing this is normal.
To test the stator/alternator, unplug the harness that comes from the stator/alternator
and goes to a three terminal plug under the seat. Check continuity between each terminal
and ground. There should be none. Check for continuity between each terminal. There
should be about .4 ohms or less.
Next, check voltage between the terminals while the engine is running. You are looking for
about 20 volts (AC) at idle and an increase of about 20 volts (AC) more per each 1000
rpm increase above that.
