Hello EV friends,

I bought and installed a new SVMC072045 Mini controller and it makes a continuous high sound like a bad transformer when turned on. As I also have got a absolutely noiseless SVMC072150 I'm not sure if that's normal or can be solved ? It's not a big problem but a bit annoying. It's connected to a 14s battery and the ignition and I disconnected all the other connections without any results. I made the hall test successful and everything works fine.

Does anyone know that or have an idea what i could try to solve that ?

Thanks for your help.
Best regards Sparfuchs
