Hello all. I have kamd 43p (kad43) volvo penta the super charger works within the correct rev range, BUT when I turn the engine off the supercharger engages momentarily. Earlier this year i ended up changing the control box and magnet clutch on the same engine. All was good. When servicing recently i noticed the problem. Any ideas thoughts would be appreicated

Morning, it only does it on one engine, the other turns off without the supercharger momentarily spinning up.
