CDI does not want to turn off continously buzzing, humming

Hi fellow pelican members,

My CDI does not want to turn off even if the ignition & engine has been shut off. the CDi continously hums /buzz. The only way to turn it off is to detach the negative cable of the Battery. When the negatve cable is reattached to the negative pole of the battery the CDI does not buzz/hum. Only when the ignition is switched on and the engine is started. When I shut down the engine there continous buzzing /humming of the CDI.
The car is an 89 911 turbo coupe USA car.


Thanks in advice guys,
