96 9000 aero (buzzing)

My ignition cassette makes a buzzing noise for a couple seconds when I turn off the engine. Then a single click and it stops. Is this normal. It runs great while running and has no other problems that I am aware of. Scott


Hello, Yes that is normal, it is a self cleaning for the spark plugs. Maybe someone else can answer for sure, but I think it happens when the engine has run for so many seconds under 3000 rpm. (Good deal)

Yes, they do that. The plugs do a series of discharges to clean themselves every time you switch off.

Yes, that is normal. It is cleaning the plugs.
