Europa-List: 914 Turbo switch on sequence ?

[R.C.Harrison <ptag.dev@tiscali.co.uk>]

Hi! You Rotax Turbo 914 buffs/operators.
My new turbo system effectively completes its testing sequence on switch
on but...whilst the motor is stopped there is still some electrical
activity like intermittent buzzing with the engine off .
Is this normal is it safe to allow it to continue?
Would appreciate a speedy response to this message.
